The best substrates for cichlids

Choosing the correct substrate for your tank is important as it aids biological filtration, enhances the habitat for your cichlids, is beneficial to live plants and on top of this, adds to the beauty of your fish tank. In this article we jump into the lively debate and explore which is the best substrate for cichlid aquarium.

Cichlids are a popular choice with aquarium owners. There are more than 1,000 species of cichlids and they are found in most parts of the world.

It is the species found in the African lakes being considered the most beautiful. Cichlids can be just a few centimeters in size or up to 90cm.

They are popular, not just because of their looks, most of them are easy-going fish that are easy to keep and fun to watch.

They are low maintenance and – if kept in the right conditions- are long-living.

Natural vs. Artificial Substrates

The first question to answer is what is substrate? Substrate is aquarium gravel, sand or any other material poured in a layer on the tank’s bottom.

Substrate fulfils several roles with the important one being that beneficial bacteria live on the substrate and there the bacteria break down leftover food, fish waste and any plant debris and this helps to keep the water clean and the balance of good and bad bacteria in check.

Experimenting with different types of materials helps determine the best substrate for cichlid aquarium.

These are usually classified as ‘inert’ and ‘active’ and this refers to whether they change the chemistry of the water in the tank so that it supports plant life.

The changes that are made are usually positive because the natural substrate contains micronutrients. Some are designed to reduce the pH of a tank whilst others leech ammonia into the water which is beneficial for the plants.

Active substrates with aragonite help prevent pH swings in fish tanks, whilst one with peat will soften the tank water and one with vermiculate releases magnesium and potassium into the water which are both nutritional to plants.

Pebbles:

cichlid substrateThe largest form of natural nitrates can also be made using artificial materials. Pebbles come in every size and color imaginable, and the natural ones are made of rock or quartz.

Pebbles look good but when they are in layers at the bottom of the tank there are large gaps between them, and these can easily trap leftover foods and fish waste which in time can build up and produce nitrates and these are toxic to cichlid (and other fish).

Live plants do not root very easily in pebbles either.

Gravel:

In reality, gravel is just really small-pebbles. Gravel is available in a variety of natural (and artificial) materials and each piece of gravel usually measures between 2-4mm.

The big advantage of choosing gravel is that the gaps between the gravel are small so it is much harder for food or fish waste to get trapped.

Food waste tends to just settle on top of the gravel so that it can be easily cleaned up using a tank vacuum.

Sand:

Natural sand is another popular type of substrate and comes in a variety of different types- just as it does on different beaches.

The grains of sand are available in different sizes from really fine to coarse and a selection of natural shades.

Aquarium Sand is a popular choice because it helps create the most natural environment for fish like the cichlid that has sand in its native home.

Sand is nice and easy to clean too as there is nowhere for uneaten food or animal waste to go except lie on top of the sand for easy removal.

Variations on sand substrates include crushed coral and crushed shells.

Aquarium soil:

This is specially formulated soil that means that it does not easily mix with tank water to become a muddy mess!

It is popular with those planting many plants in their aquarium as it is rich in nutrients which is good for the plants.

For those not wanting to plant many plants, other substrates are more suitable.

Having said that, some experts have a bottom substrate of soil so that their tank plants thrive and top this with a layer of natural sand.

Artificial substrate

There is a wide variety of artificial substrate available on the market, made from all different materials that does not affect the quality of the tank water.

Artificial pebbles, gravels, sands and soils can all be bought. Artificial pebbles for example, can be bought made from glass, beads and plastic.

Ceramic beads in a rainbow of colors are also available. Like all-natural substrate, those like the artificial beads and pebbles still form gaps where spare food and fish waste can easily accumulate.

And bare bottoms!

Some aquarium fans are adamant that there is no need to have a substrate and do not have any in their tank –this is usually referred to as a ‘bare bottom tank’.

This approach is not possible if you have fish like cichlid that like to dig in the substrate or others who scavenge for food.

The Best Substrate for Cichlids Aquarium

What is the best substrate for cichlid aquarium If you have cichlids, it is important to understand their natural living conditions. Most of the African cichlids come from the African rift lakes.

The waters in these lakes have very high mineral content and a high pH level ranging from 7.7 – 9.3. The water is harder and slightly more alkaline.

If you do not mimic these conditions in your fish tank, your cichlids will lose their color, be unable to breed and be more prone to infection.

Aquarium Ivory Coast sand is a great choice of substrate if you have a fish tank with African cichlids. This is because this substrate contains various natural minerals that are found in their natural habitat and helps keep the tank water crystal clear.

The Ivory Coast black sand is an alternative which can make a dramatic contrast with your brightly colored fish. It is more like a fine gravel than sand but contains a water-purifying bacteria that helps to detox the water.

Many fish experts recommend using coral sand, crushed coral or crushed oyster shell too. These help to balance the pH of the tank water. They prefer hard and slightly alkaline water, and this will also enhance the colors of your fish.

Considerations When Choosing Substrate

There are four important points to consider when choosing a substrate for your cichlid’s tank:

  • Size of particles

It is important to remember that uneaten food and fish waste and get trapped in the gaps between large particles/ pebbles and this will negatively impact the water quality of your tank as they decompose as the toxins build up.

It is important to consider what your cichlid wants too – they usually like to dig in sand.

  • Color

There are just so many different colors to choose from and whilst some are bright and whacky, others are totally naturally and enhance the beauty of the fish.

Darker colors can have the effect of making tanks and aquariums look smaller whilst light natural shades enhance their size. Some substrate looks dirty quickly, so this is another consideration.

  • Impact on the tank water

The African Cichlid is one of many fish species that needs certain water parameters – in this case a higher pH.

One way to achieve this is to add a substrate to the tank that will buffer the water.

Coral is a really good choice for cichlids as it does this successfully and coral sand combines the benefits of the coral on the pH and sand which is the cichlids’ favorite substrate.

  • Effect on the fish

What you choose as substrate will definitely impact your fish. Substrate with sharp edges can hurt fish.

Light-colored substrate can frighten fish– especially if teamed with bright lights.

To ensure you make a good choice, research the natural habitat and behavior of your cichlid and try to recreate it.

It is important to remember that you do not need to use just one type of substrate. If you need to use crushed coral for your tank but your cichlid much prefers sand, either invest in some coral sand – if you can find it- or mix crushed coral with sand for maximum benefit.

Some cichlid experts recommend using coral sand with aragonite. This is because aragonite is crystallized calcium carbonate which increases the hardness of water and its pH- both these are beneficial for healthy happy cichlids.

Tips for Maintaining and Using Substrate

When choosing a substrate for your cichlids, sand is considered the best. This is because cichlids love to dig in the sand and move it around.

They do scavenge for food in the wild and do make nests in the sand for their eggs. When you are putting aquarium sand or coral sand into your tank, it is best to have the layer at a depth of 2.5 – 5 cm (1-2 inches).

When you are in the pet shop wondering how much to buy, the guide is one pound (450g) per gallon of water.

Regular maintenance of the best substrate for cichlid aquarium is crucial for sustaining a balanced ecosystem.

It is important to keep the tank environment well and to remove any food and fish waste from the tank promptly and not let it start to decompose.

You should regularly change the water in your tank once or twice a week – the frequency depends on how many fish and the size of tank.

Once a month, you need to clean all the algae from the tank walls using a sponge, clean the sand by stirring in water to release all the dirt particles and check and clean the filter and pump.

  • It is a good idea to test your tank water weekly for nitrate levels and the pH. If your fish seem stressed test the water straight away to pinpoint the problem.

Final Thoughts – best substrate for cichlid aquarium

Selecting the best substrate for cichlid aquarium can significantly impact the health and behavior of the fish.

Choosing natural sand or coral sand for your fish tank will really enhance the environment for your cichlid as it will mimic their natural environment.

Keep the sand clean and healthy for your fish and regularly check the hardness of the water and its pH to ensure these are both within the ideal parameters for your cichlid.

Your fish will definitely enjoy having a substrate of sand or coral sand in their tank and you will have the fun of watching them digging in the sand and maybe even building a nest.

best spectrum for aquarium plants with discus fish

This article is all about lighting for plant growth. We’ll focus on understanding the best spectrum for aquarium plants.

Live plants add beauty in an aquarium, but they not only look good they help maintain a balanced ecosystem in the tank and have many benefits for your fish including providing oxygen, food and cover which lowers their stress levels.

To keep your plants healthy, they will need clean water, nutrients and plenty of full spectrum light to promote photosynthesis and plant growth.

Understanding Light Spectrum for Aquarium Plants

 

Different plants need more intense light to thrive, and a stronger light source is needed for taller fish tanks.

Aquatic plants thrive best under full spectrum light with a color temperature (known as a Kelvin rating) of 6,500- 8,000k.

It is essential that you choose a light source that has been designed to be beneficial to tank plants -such as high output T5 fluorescent and LED lighting.

The ‘light spectrum’ refers to the visible range of light and this is measured in nanometers according to the wavelength of the light energy – as seen by the naked eye.

This usually ranges between 400- 800 nanometers, with ultraviolet light towards the low end of the spectrum and infrared at the top end.

Visible Light SpectrumThe visible spectrum of light is often accompanied a color scale, measured in color temperature using degrees.

Kelvin Black is at the lowest temperature of zero degrees and this progresses to red, then yellow, green, blue and then violet at the warmest temperature. Sunlight is full spectrum.

It is important to understand these basics of the light spectrum when choose the lighting for your tank as there are many different types of lighting to choose from.

Light bulbs are labelled such as ‘actinic’ and ‘daylight’ and they each produce a different light for different tanks with different fish and plants.

For example, actinic bulbs produce lighting from the blue end of the spectrum, and this is ideal for saltwater reef tanks as it can penetrate deep water.

Full spectrum lights are often referred to as ‘daylight’ bulbs as they are produced from all wavelengths and are very similar to the light produced naturally in daylight.

This type of lighting is good for both freshwater and saltwater aquariums.

‘Colour enhancing’ bulbs produce light from the warmer end of the spectrum and are also ideal for both freshwater and saltwater tanks.

The different light wavelengths affect plants differently. For example, the power of red light is lost rapidly in water while blue light has penetrated the water more strongly and is more effective for photosynthesis and stimulating pigmentation in some plants.

Red light is effective for stimulating plant growth but needs to be stronger. Green is also good for aquatic plants.

Choosing the Best Spectrum for Aquarium Plants

Monitoring Plant ResponseRed and blue parts of the color spectrum have advantages although they are often lacking in light bulbs.

The first is that they will accentuate the color of the plants in your tank. However, it is important that the light bulb you choose also has green/orange/yellow spectrum too to give a balanced effect – although these colors will have less impact on your tank plants.

Stronger red/ blue lighting will also stimulate pigmentation in certain plants. Especially those with red leaves and out of the two, the blue spectrum of light is more important.

The plants will grow healthier too and be fuller in shape with more leaves.

Although the coloration of your plants is affected by the nutrients you give your tank plants, lighting plays a key role too.

It is said that having more blue in your light spectrum will mean there will be more algae in the tank, but this has not been proved.

When buying your aquatic plants, it is a good idea to ask for guidance about their light requirements.

T5 lighting, the strongest and ideal if you want a densely planted tank and you can plant the most light-needy plants in the center of the tank where the light is strongest.

The ‘rule of thumb’ is that you will need 1-2 watts per liter of water, but this calculation will need to be adjusted according to the type of fish you have and the depth of your tank.

For example, light from a fluorescent tube usually only penetrates the water to a depth of 60cm which may not be enough if you have a deep tank.

  • It is important to remember that most species of aquarium fish come from the tropics where there is an equal amount of day and night so they will need to have 12 hours of light. It is best to maintain the day/night cycle. Leaving your aquarium lights on will encourage the growth of algae.

Best Spectrum for Aquarium Plants for Different Stages of Plant Growth

Best spectrum for aquarium plants and optimal healthCertain light spectrums trigger the growth of different characteristics in aquarium plants – at different stages.

For plants to optimally absorb the chlorophyll in the process of photosynthesis both blue and red light are the most efficient, but at certain stages the strength of each can make a difference.

Early growth and seedling stage

The blue light spectrum (400-500 nm) is essential for both seedlings and young plants as the light encourages them to establish a healthy root and stem structure during vegetative stages as they establish a healthy root and stem structure.

Vegetative growth stage

Blue light spectrums are credited with encouraging the vegetative growth stage and the structural growth of plants.

Flowering and fruiting stage

The best spectrum for aquarium plants light spectrum for this stage is the red (600-700nm) as is the one best absorbed by chlorophyll pigments.

Red will promote flowering and fruiting as well as helping stems to develop and leaves to grow.

It is red light that plays a key role in the plant’s maturity and its size.

  • There is, however, no single light spectrum that will guarantee a larger crop.

Types of Aquaria Light and Their Spectrum

A. Full Spectrum Lights

discus-tankThese tank lights are often nicknamed ‘daylight bulbs’ because the light they emit mimics natural daylight.

This type of bulb emits light at all visible wavelengths, so they are considered good all-purpose lights to choose for an aquarium.

LED lighting is relatively new in the aquatic world and proving very successful.

An LED light can last five years, making it economical – especially as running costs are low too.

LED lights can be used really creatively too, and a bonus is that they do not generate much heat.

C. T5 and T8 Fluorescent Lights

These are the most common types of aquarium lighting.

Both can be used to help your tank plants develop, but the T5 is more powerful so is recommended for best spectrum for aquarium plants. Especially if you are cultivating your tank plants densely.

If you have plants that demand a high level of lighting, two T5 fluorescent tubes could be good.

D. Metal Halide Lights

Metal halide lights have long been popular for their energy efficiency although the Performance of LED lights is far better.

Having said that, a new 400-watt metal halide light will last up to 20,000 hours.

Metal halide lighting is intense, so they are a good choice for deep aquariums or if you need wide coverage.

This type of lighting does generate more heating and require more maintenance. Radium metal halide bulbs are purpose-built for growing corals in your tank.

LED lighting is fast becoming the popular way to achieve the best light spectrum for your tank, but there are some good tips to help you achieve the optimum lighting.

Proper Placement of Lights

Research this a little, based on the type of fish and plants you have as their requirements will differ, but cool running and energy-efficient LED lighting suits many tanks and can provide the best spectrum for aquarium plants.

Using Timers for Consistency

It is important to be consistent with the timings for your aquarium lighting and a timer definitely makes life easier.

You want to have a good day/night balance for your tank with a maximum of 8 hours of light on full power and up to four hours at a lower strength- this will resemble natural sunshine as the midday sun is very different to early morning and evening sun.

If you set your timer for longer than this, you could damage your plants or encourage algae.

Adjusting Light Intensity and Duration

Understanding the best spectrum for aquarium plants

The best way to measure light intensity is using PAR (Photosynthetically Active Radiation) numbers which are provided by tank light manufacturers to inform customers so that they can buy the light most suitable for their aquarium.

A PAR value of 75-100 μmols offers light for plants needing low light intensity, 125 ~150 μmols, for plants requiring medium light intensity and 200 μmols plus is for use with high light demanding plants.

The main consideration will be the depth of your fish tank as this will affect the amount of light penetrating to the bottom of your fish tank.

Generally, it is recommended to start off with low light in your aquarium as this is suitable for most aquatic plants.

Monitoring Plant Response

Your fish tank will have an ever-changing eco-system that will need to be monitored to ensure that you have got the lighting right.

When you have a new aquarium with young plants, less light will be needed than when the tank and its plants have matured.

If you have to make adjustments, always note down the light settings so that you can see what adjustments are working.

If you have the lighting very bright and the algae seems to be flourishing, it is best to turn the light intensity down.

When you start lighting your aquarium choose a light intensity of 20-40% brightness and slowly increase the intensity if there is no algae bloom. If algae does develop, you will need to lower the lighting again.

  • If you have any persistent problems, ask at your local aquatic center for advice.

Real-life Examples and Case Studies of the Best Spectrum for Aquarium Plants

The amount of light in your aquarium is crucial if you are growing aquatic plants because without the right amount of light in the correct color spectrum they will fail to thrive and simply die.

You must tailor-make the lighting in your tank fit the environment you are creating, and this depends on the type of fish and plants you choose, and these choices are usually made depending on how much time you can dedicate to caring for your aquarium.

It is well worth seeking advice on your choices to avoid disappointment. All plants have different light needs but generally, the more light a plant requires, the harder that plant will be to grow successfully.

A much-quoted case study focuses on the beautiful Glossostigma Elantinoides.

When it is healthy and thriving, this gorgeous aquatic plant covers the floor of the fish tank like green velvet grass.

To achieve this is far from easy as this plant is really tricky to grow. It requires intense lighting and because of this, there is usually a battle with increased algae levels.

If the algae is kept in check, to keep the plant looking good takes time to keep well-fertilized and pruned and
another requirement is more frequent water changes.

Not surprisingly, many enthusiasts ditch their ideas of being successful and plump for easy-care plants instead.

Final Thoughts – Best Spectrum for Aquarium Plants

The success of your aquarium plants will depend on the lighting you choose and getting the best spectrum for aquarium plants.

It is essential to research the best spectrum for aquarium plants well as ideas will differ depending on your tank size and the types of fish and plants you have.

Your goal is to get the perfect balance in your aquarium between light, CO² levels and fertilizer.

When you achieve this, your fish will have a healthy environment and your tank plants will be flourishing and making keeping your tank well-maintained surprisingly easy.

[Complete Guide] Best Fish for 5 Gallon Tank (With Pictures)

A five-gallon aquarium or cube is the smallest size that can acceptably keep fish. If smaller than that, then it translates into trouble in maintaining stable parameters. Even the littlest fish do require extra room to move and explore. This volume will limit your choices in fish but can still set up a vibrant and entertaining tank. Let’s go through Best Fish for 5 Gallon Tank.

Stocking a 5-gallon tank.

Any tank with a water capacity below 10 gallons is called a nano tank. The aquarist can use a 5-gallon storage tank to store small fish and invertebrate species. With its small size and capacity, it can be easy to overstock. This article enlightens you with the suitable fish species and inverts that can be kept in a 5- gallon tank and include the best stocking ratio and proper maintenance guidelines.

What freshwater fish should I put in a 5-gallon tank?

What freshwater fish should I put in a 5-gallon nano tank? With this limit on water’s volume, every centimeter counts. Most people have preferred to keep small creatures such as invertebrates and small fish with minimal food waste. Toxic waste builds up faster in smaller volumes of water, mainly if you are a new fish-keeper. I never assumed that five-gallon tanks would be as easy to keep.

Why have a 5-gallon tank

A 5-gallon tank nano tank is the better option for those who do not get much space. A smaller aquarium forces you to make more critical decisions and a righteous maintenance schedule. Most schooling fish are not ideal for a 5-gallon aquarium because they feel more anxious when alone. Small schools usually are what you can safely keep.

Overview of a 5-gallon tank

We could have 20, 55, or 100 gallons of water to fill, but the lack of bigger fish doesn’t mean we have a beautiful system. Nano tanks can equally look unique and full of life with the right fish and plants.

Why a 5-gallon tank?

5-gallon tanks should be the smallest you can get for success at fish keeping. The environment and water quality in highly unstable in those nanosystems. In this guide, we introduce the best fish for a 5-gallon tank. In a small place, an aquarium is a perfect decoration centerpiece.

Tropical freshwater 5-gallon tank basics

Keeping a nano 5-gallon tank is usually a challenge, but it will look like an underwater fairy tale land. Don’t be fooled by the fact that a smaller aquarium would require less work and maintenance than a large one. The numbers of the fish that can be kept in a 5-gallon container depend upon the species of fish you’re want to keep. We will be able to explain the proper design of a 5-gallon fish tank later on.

5 Gallon Nano Tank

There are a surprising amount of options available in regards to the best fish for a 5-gallon tank. While you can keep most of these fish in a 5-gallon tank, we usually recommend, if possible, a bigger tank. Fish like Guppies, Endler, and Killies can survive in little space thanks to their tiny size and habits. They are one of the easiest species for fishkeepers; they are not very demanding.

5 Gallon Tank Stocking Ideas And Combinations

We will show you several other species of fish for a 5 gallon. A bigger tank is easier to manage and allows you to keep a wider choice of fish. We decided to look at some of the best fish to help you get the best combo and the stocking ideas.

How do I stock a five-gallon fish tank?

If you are thinking about building a five-gallon aquarium, it’s simple to get confused by the overwhelming amount of information available on the internet. Keep reading to learn more about preserving one of these nano tanks!

What to consider when stocking a 5-gallon tank

A nano tank can reduce the number of your options of fish. Only some species are likely to prosper and do well in one of these small tanks. Certain varieties of reef fish can thrive in the small nano aquariums. Small tanks are attractively built, which can be kept at even a work table, and are often much cheaper to maintain than larger models.

How do you keep a fish in a 5-gallon tank?

Having and keeping your nano aquarium can be tricky. You should know how big your fish will get when fully grown. It would be best if you didn’t mix a peaceful fish with aggressive species. You can combine many species we list as above because their bioload is relatively tiny. You should find out which fish you want to keep. No overstock is advised.

How to stock a 5-gallon tank?

More life in your tank, more quickly it becomes dirty, needs more maintenance, and water changes. Slowly populate the tank, looking closely at your water parameters and your fish and system; small water tanks quickly become toxic. Live plants are welcome when they do not remove swimming space from fish.

How many fish can you fit in a 5-gallon tank?

How many fish you could keep in this size tank depends on the type of fish you intend to use. There are plenty of choices to choose from, but this article limits it to just some species that will prosper in the tank.

Set up of 5-gallon fish tanks

A 5-gallon tank is an ideal choice if you have limited space or want to start a small budget project. A giant aquarium is always recommended as even smaller critters need room for swimming and exploring. As counterintuitive as it sounds, nano tanks are cleaner and less dirty than bigger tanks. The waste your fish will inevitably create is a biological imbalance that becomes harmful and deteriorates the water quality within your nano tank. Design the tank with enough decorations to help fish hide and relax and leave enough room for free swimming requires a lot of creativity.

Planting and decorating

It is nice to cultivate some living plants in your nano aquarium for cycling nutrients, ornamental beauty, and providing a hiding place for the fauna. Decorations are exciting additions to aquariums because they contribute to replicating the native habitat of fish, shrimp, snails, etc. Add pieces of driftwood, rock, and caves in the tank, which inhabitants can hide in. Several of them should be acceptable for a five-gallon. Live plants not only improve the visual appearance of the tank they also promote water quality. The overall aim is to create a healthy and balanced environment for tank residents and ensure they thrive for a more extended period.

Planting

A well-planted tank will brighten every space and bring in a minor nature in your home. Some plants remain relatively small and do not require much maintenance. Even with a small amount of water, you can create your little forest.

Best live plants for a 5-gallon tank

In addition, plants also offer a suitable nesting spot for shy critters. In a 5-gallon tank, you want to choose a small aquatic plant. They are low maintenance! Even a few healthy plants will make a big difference in how stable water quality is kept.

Suitable fish & inverts

Some delightful fish and invertebrates will flourish in a 5-gallon aquarium. Considering that you should only add fauna after the aquarium is mature, the aquarium must be fully cycled before receiving its inhabitants due to the low volume of water and vulnerability to water quality degradation. In a 5-gallon aquarium, it is easy to alter the water’s chemistry which can cause fatality to the inhabitants before you even realize it. When going for Dwarf Crayfish, be sure to pick one of the smaller species, such as Cambarellus diminutus, and not the larger Florida Crayfish (Procambarus alleni). You can quickly put together dwarf shrimp species – like red cherry shrimp – or snails – like nerite snails – in pretty much all of the situations; even if you go for a Betta, it’s an excellent and striking combination.

Popular Stocking Combos For A 5-Gallon Tank

All species in an aquarium tank need to be compatible in good conditions. Generally, it would be best if you aimed to include species without worrying about each other behavior. Here are some different fish that you should consider keeping and combine. Cardinal tetras have torpedo shape bodies and striking blue and red colors. White cloud mountain minnows are named from where they came from. Sparkling gourami is pretty active, swimming all over the tank, mainly in the upper part of the water column. Molly fish, or mollies as they are affectionately known, are another household favorite. Endler’s livebearers are a unique species with a torpedo body but with a large and colorful fin. The chili rasbora is considered a nano fish, only reaching approximately 0.7 inches. The best fish in a 5-gallon tank should plan for low flowing water and tons of live vegetation.

Killifish

Many species are small, averaging 2 inches long; they are usually kept in pairs and bred in small aquariums. It is maintained without problems in the five-gallon aquarium. Trumpet snails are an excellent way to clean debris from tanks. Amano shrimp is a great tank companion. Shrimps and snails are the best way to keep your tank clean of algae and food debris, and they can also eat fish eggs. Some species of killies can be aggressive to each other and other fish.

Guppies (Poecilia reticulata)

A tank stocked with only two male guppies will cause a rush of competition when feeding them. Try to keep a small group of females and fewer males. The problem is that a 5-gallon tank will rapidly fill with fry guppies. Guppies are much more intense and energetic than betta fish and are ideal for fishkeepers who want to see fish swimming around the glass with excitement for the next meal or anything else. Male guppies come in various colors and shapes, from colorful redtails to panda-colored. It would be best if you kept female and male guppies in clumps without violence. Get more information from our Guppy article!

Cherry Shrimp (Neocaridina davidi)

Unlike fish, cherry shrimp do not excrete too much bioload, and thus they don’t generate much waste. So with 10cherry shrimps in a 5-gallon tank, you will not be dealing with ammonia spikes caused by the same number of fish that would probably create. Cherry shrimp flourish in the same conditions & care in the same ways as bettas and guppies and are harder animals and easy to keep than you thought. No RO water or special salts for shrimp are necessary. Use conditioned tap water for water changes in the cherry shrimp tanks. They are the perfect species for beginner aquarists and expert fishkeepers who are adventuring into nano fish tanks.

Corydoras Pygmy

Corydoras, corys, or cory-catfish are small tropical freshwater catfish that live in shallow waters. They prefer to be in schools, and 5g / meter tanks don’t provide much space for many Corydoras species, but some are dwarf or pygmy species that you can keep inside nano tanks. A sponge filter is perfect for a small fish as these filters prefer less water flow. These cute animals look fun as they slide around your tank. They make a great addition to any planted tank and can be one of the best fish for a 5-gallon tank if you keep their water quality and avoid overfeeding.

Fish to avoid

Some fish are often recommended as suitable for five-gallon tanks while doing much better in a larger tank. They’re too active, grow too big, and cannot cope with water instability. Try to study each species you want to keep and use good sense when stocking such small tanks. Even some species of Rasboras, which are always listed as great fish for small aquariums, require more than 5 gallons to thrive. The same happens with some species of Gouramis, even if they are dwarfs.

Fish you shouldn’t keep in a 5-gallon tank.

Fish that do not accept tanks prone to suddenly changing the water parameters shouldn’t be kept in a 5-gallon tank. Angelfish are big-sized fish to be held in any nano tanks, but even if marked as juveniles, they will not survive because of the stress. Oscar fish and similar-sized cichlids will soon outgrow a 5-gallon tank and have a hard time as juveniles because they’re very active and territorial fish. Almost all kinds of catfish, cichlids, barbs, and many tetras and livebearers are far from thriving and merely surviving in those small systems.

Fish not to have in a 5-gallon tank

Goldfish and Carps are large size fish and great waste producers, which makes the perfect mix to crash the system of a five-gallon container. Dwarf cichlids can fight to the death if kept together or get super stressed if left alone; in such a small space. Other species of cichlids are terrible residents, as they grew large and are highly active and aggressive. Loaches are out of the question, even dwarf ones because they need water with a fast flow and excellent quality. Virtually any fish that grows beyond 1 inch, is aggressive, territorial, or lives in huge schools are impractical to be kept at this tank size.

Why should I buy a 5-gallon tank?

Nano tanks can be easily installed under counters, desks, or any other place, and naturally, it costs a lot less money. However, a 5-gallon fishing tank can have some severe cons too. It limits the number and types of species and inverts to be housed in it. Larger tanks allow you to stock schooling fish best kept in groups of at least six individuals. They need open spaces to hide from stressors or relax for them swimming in the water.

Keep in mind…

How to design and maintain a perfect nano tank? Tell yourselves about what is best for the fish species that you want to keep. Remember, understocking is always better than overstocking, and choosing a safe population can avoid many troubles over time.

Safety in numbers?

Several species are shoaling fish that become highly stressed and fragile if not kept in teams of six to five individuals. Tiny animals are particularly vulnerable to stress when kept alone or even together. In nature, a large shoal of nano fish looks a lot safer than living alone or accompanied by one partner. Find out here if the fish you are considering buying meets your requirements and is suitable for a 5-gal tank.

What do you think?

We hope that what you learn from this article has been beneficial. Remember always test your water constantly, understand the variation of parameters on your nano, carry out scheduled maintenance, and keep an eye on your animals and plants; this way, you can prevent almost all significant problems that major aquarists face.

Conclusion

A 5-gallon tank is used for those who want to be challenged. Putting too many fish in one place can quickly result in the collapse of the tanks and the death of the fish and inverts. If you want to create a vibrant ecosystem, consider buying a 5-gallon aquarium and filling it with plants and understock with fauna. The rewards for small tanks are derived from the effort and concern we put into them. The compensation for an aquarist is due to our hard work and effort in the tank.

Guidelines for stocking your 20-gallon tank

However, in some aquariums, owners overstock their tanks often. It can be considered certain factors for measuring safe stocking levels.

Guidelines

Generally speaking, your guideline for stocking your aquariums is about its filtration system and common sense about physical space for fauna to swim, hide and have a peaceful corner in the aquarium. For this, perform tests to assess the aquarium’s water quality, know the efficiency of filtration, and find out if your aquarium is full of fish.

Stocking your freshwater aquarium

A 20-gallon aquarium allows you to keep many live plants and various beautiful freshwater fish, and exciting animals. I listed some of the most fantastic fish for a 20-gallon tropical tank. Every fish, critter, plant, and decoration in a tank play a role in the health of the aquarium. The goal of making these micro-ecosystems is to build one that requires as little effort as possible to keep going.

Livebearers

Livebearers are freshwater creatures who give birth to tiny fry. These fishes may be the most commonly encountered within an aquarium, with most coming from the family Poeciliidae.

It includes guppies, mollies, swordtail, platys, and others. One benefit of keeping livebearers is that they’re easily bred. There are many species where the males fight each other when trying to mate.

Bettas

Bettas are slow-swimming fish. They most often swim on the top of the tank. Shrimp can also live with betta fish, but you have to provide them with hiding places not to become a meal for the fish.

Siamese Fighting Fish can thrive in a 20-gallon aquarium. Choose peaceful but quick-moving fish for tank partners; avoid fin nippers.

Tetras

Neon tetra fish are most widely used for aquarium fishing. Tetras generally have tiny, compressed, and brightly colored bodies. Other than Neon Tetra, Black Neon Tetra can also do well in 20-gallon tanks.

They’re easy to rear. It’s best to keep them in schools of at least six fish. Other tetra species include the Rummynose Tetra, the Black Phantom Tetra, and the Glowing Light Tetra. Tetras can make an essential part of the aquarium.

Cichlids

You can keep dwarf cichlids in a 20-gallon tank. Angelfish, Discus, and other cichlid grow pretty massive and rapidly to be held in a 20-gallon tank. Dwarves can get territorial during the breeding process. It is not uncommon to keep Rams and Apistos in these sizes of tanks.

Dwarf Gourami

Dwarf gouramis are the only fish in this list I’d consider semi-aggressive. In general, they are mostly peaceful and can offer superb communities fishing.

If there are two, they can fight, or you may bully either partner. To reduce the chance that this happens, try to avoid using two males in the same tank. It is also a good idea to provide an area in your aquarium so that a bullied animal can hide.

Can you list the best fish combinations for a 20-gallon tank?

In general, when filling your 20-gallon tank, try to have one or two bigger “centerpiece” fish and fill the rest with a class of smaller fish and a few bottom dwellers like snail or shrimp.

In general, twenty-gallon tanks should be a perfect size for a novice tank owner. And always remember that it’s crucial to understand the nitrogen cycle and how to maintain healthy water conditions for your fish.

Danios

Zebra Danios are exceptionally active fish that generally stay in the upper areas of an aquarium. They are native to South Asia and rely on a large tank because they love swimming and chasing other fish.

Other Danios can be kept in 20 gallons of tanks, including Danio Marginatus, Pearl Danio, and Celestial Pearl Danio. These fish can also fight with other fish, such as guppies and others, so be aware when stocking up your aquarium. The danios zebras are happier in groups with five to six fish.

Rasboras

Rasboras are possibly the best kind of fish for small community tanks. These fish also originate from freshwater habitats in Southeast and South Asia. Due to their peaceful nature, they are excellent tankmates. Also, these fish shows unique breeding and shoaling habits, all with fantastic color. These examples of common Rasbora species regularly held in aquariums are Red-Lined, Pygmy and Harlequin.

Corydoras

Cory catfish are an excellent addition to any tank. They will eat leftover fish foods that get lost in the tank. They’re big-bodied schooling fish.

Tell me the biggest fish you can put in a 20-g bag?

You want to keep fish less than 6 inches in size. Fish has to have space in the tank to swimming and also relaxing. Avoid keeping large numbers of fish in a small tank.

Additional factors

Any extra addition to the tank will reduce the amount of space that is available to the fish. Plants and gravel could also impede the flow of water in the tank.

Always add filtration and aeration. But you shouldn’t rely too much on such aid, as any blackout will be disastrous; keep an eye open.

Fish You Shouldn’t Keep In A 20-gallon tank.

There is also lots of fish that should never be kept in a 20 gallons tank. It’s not acceptable to fill tanks with large cichlid or other large fish.

Angelfish are territorial species that have a semi-aggressive temperament and can kill smaller fish. In addition, Common plecos grow faster even as juveniles as they can occupy all the tiny tanks in a short time.

Goldfish can die prematurely in small aquariums.

Best live plants for a 20-gallon tank

Planting Vallisneria in your 20-gallon tank is the best way to turn your nano aquarium into an aquatic jungle. Amazon’s Sword is a good option for nano tanks.

Sagittaria dwarf has a grass-like appearance. A lot of Wisteria species can make excellent places of cresting for fish. It flourishes with liquids or tablets of fertilizers and tends to take over the underwater landscape as it can propagate via side shoots. It is easy to take care of.

Size considerations

Many times the fish bought in the pet store are youngsters that will grow more. Check the average size of each fish when mature, and use this measurement to figure how much space the fish need. It’s not unusual for a fish to double in size pretty quickly.

Specific needs

Most fast swimmers need more area than slow swimmers, even though they tend to be active all the time. You’d better give your fish plenty of room to eat, which helps protect the peace by decreasing the number of unpleasant encounters.

Some large fish will produce more waste than much smaller fish and can alter your storage capacity or tank filtering ability as well, when in a 20-gallon tank.

Lights for a 20-gallon tank

Lighting is critical to fish to maintain the day and night cycle. Although there are plenty of lights available, it is better to turn off their tanks at night. Adjust in the minimum of 12 hour light and 12-hour dark.

Fish tank filtering system in a 20-gallon tank

That filter is the critical component in every tank. Filters keep good bacteria and make sure to keep the water free from pollutants for longer. The best the filter system, the healthier the fish, and the less maintenance is needed.

20-gallon tank water heater

A simple water heater offers a better quality of life to the 20-gallon fish tank residents. The heater is essential to keep the temperature stable; the fluctuation of this parameter and others can cause a drop in the fish’s immune system, causing diseases and other pathologies present in the tank to appear. It’s easy to set up a thermometer when looking for a quick and easy way to monitor the temperature.

The last step is adding water.

Once you have assembled the basic structure with the tank, heater, filter, lighting, plants, logs, and other decorations, it’s time to fill it with water.

Depending on the substrate you use, the water can get murky the first time you fill the tank, and you might have to wait for patience till the debris settles in.

If you add some fish to your new tank – without cycling it – you’ll have to perform numerous water changes; otherwise, you will have a big ammonia problem. Before adding fish, keep your tank going (while full of water) for 2 to 4 weeks for the bacteria to attach themselves to your filter so that they can carry out the nitrogen cycle and be able to maintain a good quality of water in your aquarium.

Good luck with your aquarium!

A 20-gallon aquarium includes stocking options outside of its 10,000-gallon capacity. If you want big fish or many fish, you will probably be better off getting a 55-gallon tank or bigger.

Or if you’re going to set up a small community with some beautiful fish and maybe some excellent plant, having one this size will probably suffice. This article is not meant to supplement diagnosis, prognosis, treatment, prescription, or a qualified veterinarian’s formal guidance.

Final thoughts

A 20-gallon tank is a perfect aquarium for any beginner. It provides a chance to care for different animals without taking too much space. Always ensure to keep track of the size of the fish species when stocking.

In any case, ensure it is the right environment for the species of your choice. Set up and decorate the aquarium correctly with a heater, filter, plants, and everything else you want.

Remember to make space available for the animals to swim, hide and rest whenever they want. Use common sense when populating the tank, and know the habits of the fish you want to keep; this will help you choose which area of the aquarium to occupy.

Keep your maintenance routine up to date, keeping your water always in perfect condition; that way, you shouldn’t have any problems.
