Caring for Black Moors in an Aquarium

The Black Moor is a distinct variety of Goldfish, reaching a length of 6-8″ when fully grown and boasting an impressive lifespan of up to 20 years.


Their endearing appearance includes round, stubby bodies, contrasting with the sleek, streamlined shape of standard Goldfish.

With fancy, flowing fins and a predominantly black coloration, they make for an intriguing and visually appealing addition to any aquarium. Notably, their prominent eyes have earned them the nickname “telescopes”.

Black Moor Goldfish (Carassius auratus) are characterized by their curved body shape, which contributes to their slow swimming speed.

Younger individuals display fewer dark colors, which gradually deepen with age.

The Black Moor Goldfish features dark metallic black scales and distinctive telescope eyes.

Like other Goldfish, it has a potential for significant growth and requires a spacious aquarium or pond when fully matured.

Origins of the Black Moor Goldfish

Black Moor goldfish have been selectively bred for their distinct characteristics. These early forms of Goldfish were introduced to Japan in the 1500s, where their long tail fins and vibrant color patterns were further enhanced.

Today, these famous goldfish can be found worldwide, captivating fish enthusiasts.

In the early days, these fascinating creatures were isolated in pools by fish keepers, who regarded them as intriguing oddities.

Types of Black Moor Goldfish

The Black Moor Goldfish shares the classic short, egg-shaped body characteristic as do some other goldfish types. Like other telescope varieties, its eyes protrude from the sides of the head.

While the original Black Moor had a fantail, modern types often feature shorter, flowing fins. The eyes of these fish can vary, with some appearing as smooth cones and others having creases or a balloon-like shape.

Other black Goldfish varieties, such as Black Oranda, Black Lionhead, and Black Ranchu, have normal eyes.

Breeding projects have resulted in a range of fancy black Goldfish, including the Black Ryukin. Additionally, the Black Comet Goldfish is sometimes referred to as the Black Bubble Eye Goldfish.

Origins and Habitat

The Black Moor Goldfish was developed through selective breeding in China and Japan, focusing on its distinctive genetic trait of telescope eyes. By isolating fish with these eyes in a specific pond, multiple smaller spawns were obtained.

The breeders then worked to establish the desired permanent traits, including the unique black coloration and long body fins.

Telescope Goldfish


The Black Moor Goldfish stands out easily among other species. It grows to 6-8 inches (15-20 cm) and has a round, egg-like shape that slows its movement in water.

With big bulging eyes, their eyesight is limited, but eye infections are rare.

They are predominantly black, although some may have orange or gold on their bellies.

Color development in Black Moor goldfish:

Young Black Moor fish may have a brownish bronze appearance, but as they mature, their coloration becomes vibrant, and their eyes become more prominent.

Some breeders suggest that hot water can reduce black pigment fixation, resulting in a bronze appearance instead.

Genetic factors and age may also contribute to a reduction in black coloration as fish grow older. Even mature fish can lose black coloration if kept in warm aquarium water.

We will discuss water quality later.

Look & Varieties:

Male Black Moor goldfish have a slimmer body compared to the shorter and stockier females.

Some individuals exhibit an elegant flowing black tripod tail, which is usually more prominent in females.

It’s important to note that black coloration in Goldfish can be unstable. There is no guarantee that the black color of a Black Moor will remain consistent over time.

As the fish mature, their black pigmentation develops, but factors such as old age and water temperature can cause the black pigmentation to fade. In some cases, fish develop a white belly.

Black Moor Goldfish Habitat and Tank Conditions:

Goldfish, including Black Moors, are selectively bred and not found in natural habitats. Their ancestors, Asiatic carps, reside in murky freshwater bodies like lakes and rivers.

To ensure their well-being, create an optimal tank environment.

Maintain a pH of 6.8-8.0, ammonia and nitrite levels at 0.0, GH/KH of 6-10 degrees, and a water temperature of 65-75°F.

Additionally, provide slow-moving water and use sand as the substrate in the tank.

Feeding your Black Moor Goldfish:

To maintain the health of your Black Moor Goldfish, provide a balanced diet consisting of high-quality fish flakes or pellets.

Supplement their meals with meaty protein sources like frozen brine shrimp, bloodworms, and krill. Include healthy vegetable treats such as lettuce, spinach, and broccoli occasionally.

Avoid relying solely on store-bought products for nutrition and ensure a varied diet with both plant and animal-based foods.

Offer small amounts of food that can be consumed quickly to prevent overfeeding and water pollution.

Soak frozen and dry foods in tank water before feeding to aid digestion and prevent constipation. Remember to rinse vegetables thoroughly before offering them as food.

Round-bodied goldfish are highly susceptible to swimming bladder issues, and good nutrition can help prevent digestive problems.

Black Moor Goldfish Tank and Compatibility:

When housed in a community aquarium, Black Moors require peaceful tank mates. Their graceful swimming adds enjoyment to the tank’s ambiance.

Due to potential poor eyesight, these fish have a slower swimming pace compared to other species. They are not well-suited for ponds where competition for resources can be challenging. Their slow movements also make them vulnerable to predators such as cats.

It is recommended to provide a spacious tank with a volume capacity of at least 100 gallons.

Black Moors can also thrive in tropical tanks with water temperatures up to 25°C.

Avoid placing the aquarium in direct sunlight to prevent sudden temperature fluctuations, as they can cause health issues for the fish.

Aquascaping a Black Moor Goldfish Aquarium:

Goldfish, including Black Moors, have a tendency to dig, so it’s important to avoid having food in the gravel bed. This can lead to water quality issues like cloudy water, algae growth, and spikes in nitrite levels.

Use larger smooth stones to protect plant bases from digging. Goldfish will uproot and damage aquarium plants.

The fish may also explore caves and other ornaments in the tank as they are curious creatures. However, avoid using sharp and pointy decorations to prevent any harm to telescopes and bubble eye goldfish.

Black Moor Tank Considerations:

Black Moor goldfish produce a significant amount of waste, which can quickly lead to water pollution.

To accommodate their needs, it is recommended to have a minimum tank size of 100 gallons (380L).

Due to their less agile swimming ability, it is advisable to provide a spacious tank rather than filling it with small schooling fish, ornaments and plants.

If you choose to include plants, real or artificial, position them at the back of the tank and regularly trim them to ensure there is ample open swimming space for your fish.

To provide them with an ideal tank environment, opt for a longer tank shape rather than a tall one. This design allows for more horizontal swimming space, which better accommodates their swimming style.

Aquarium Filters for Blackmoors:

Properly size the biological filtration based on the aquarium’s inhabitants and size.

Keep maintenance organized and ensure the water flow is low.

There are various types and models of filters available, so seek assistance from the seller to determine the best fit for your system. Internal canister filters are often recommended as they are simple and cost-effective for Goldfish.

Regularly clean the filters and substrate, and perform weekly water changes, even with filtration in place.

Maintenance and Care:

Regularly clean the tank and remove any leftover food to maintain cleaner conditions. Perform water changes on a weekly basis.

Be mindful of the tank design to avoid placing anything that could harm the fish.

Goldfish care is relatively straightforward, making them suitable for beginners and capable of providing companionship for many years.

Care Level:

The Black Moor Goldfish is low-maintenance and easy to care for. They have no specific requirements for survival and can live for a long time with proper care.

Providing ample space is essential for their well-being.

It’s important to be vigilant for common Goldfish ailments like dermatitis and swimming bladder disorder and address them promptly.

Pay attention to any unusual behaviors exhibited by your fish, as they may indicate illness.

Maintaining a clean environment is crucial for their health, and isolating any sick fish in a separate tank is recommended. This will help reduce stress on your fish and appropriate treatment can be given.

Carassius auratus

Temperament and Behavior:

Black Moors are calm and slow swimmers that can easily entertain their keepers. They prefer the company of fish with similar temperaments, often staying close to their own species.

They typically occupy the middle part of the water column but seek hiding spots among plants, near the substrate, or within tank decorations.

Black Moors tend to be solitary. They may hide in the tank if they feel threatened or overwhelmed by other fish.

Tankmates for Black Moor Goldfish:

When choosing tankmates for Black Moor Goldfish, it’s important to consider their slow-moving nature and delicate fins. Avoid aggressive and fast-swimming fish that may outcompete them for food.

Ideal companions include other fancy Goldfish varieties like telescope or bubble-eye goldfish.

Keeping at least two Black Moors together in a suitable tank is preferred.

Avoid aggressive predator fish like Oscars, and opt for peaceful invertebrates such as shrimp and snails. Fish like Bristlenose plecos and Kuhli loaches can also be compatible.

Ensure each fish has enough swimming space and maintain a well-decorated tank to prevent any bullying or stress.

Sexing Black Moor Goldfish:

Males of this species tend to be larger than females, although sexing them can be challenging due to subtle differences. However, distinguishing between the sexes becomes easier during the breeding period when males develop visible white bumps called breeding tubercles on their fins.

Females will grow plumper as they become heavy with eggs.

Breeding Black Moor Goldfish:

To breed Black Moor Goldfish, mimic the spawning conditions of spring in the wild. Provide plenty of spawn substrate like roots and mops for the females to lay their eggs.

To stimulate breeding, feed the adult fish with a quality diet then raise the tank temperature slightly (simulates the warmer weather of spring in the wild).

The males develop small white bumps that appear on their gill covers, these are called breeding tubercles. The females will swell as their eggs develop. She will often show a bulge to one side of her abdomen.

The males will begin to chase the females around the tank. She will release eggs in the spawning substrate and the males will fertilize the eggs.

Each pair can hatch around 10,000 eggs within two days. The adults will eat the eggs if left in the tank, so they should be removed once spawning is complete.

It is crucial to monitor water quality as the eggs develop and then begin to hatch. Infertile eggs will pollute the water. Give daily water changes and add Methylene Blue to stop bacteria.

Feed the larvae a nutritious diet for the first two months and gradually transition them to similar food as their parents. Allow the egg sack to be absorbed, then feed them very small commercial fry food, or newly hatched brine shrimp.

Black Moor Goldfish Lifespan:

With proper care and suitable tank conditions and size, Black Moor Goldfish can live up to 20 years.

They have a typical lifespan of around 18 years, but with excellent water quality and meticulous care, they can exceed 20 years of age.

Hardiness and Diseases in Black Moor Goldfish:

Black Moor Goldfish are generally hardy and resilient if water parameters and quality are well-maintained. However, they can be prone to certain health issues.

Care should be taken to prevent physical injuries from objects or entanglement in nets.

Common diseases that may affect them include urinary system infections, fungal infections, hole in the head, ich (white spot), popeye, slime disease, swim bladder disorder, ulcers, and velvet.

Changes in coloration should be monitored closely, as they can be a natural part of growth or indicate an underlying disease.

Final Thoughts

Black Moors are known for their calm nature and are compatible with slow-moving or fancy goldfish. They have difficulty swimming in fast-moving waters and are not suitable for shallow ponds. They prefer safe and smooth tank decorations and vegetation.

Black Moor Goldfish require proper care and should not be kept with incompatible tankmates. They produce more waste compared to other goldfish varieties.

Overall, they are relatively easy to care for, but proper research and consultation are recommended.

They should have a capacity of 50 gallons or more. Please read more articles on this site!

Reverse Osmosis

Some people choose to utilize the reverse osmosis filter for removing water minerals. These work by pumping water through a permeable membrane, removing small particles and debris such as chlorine and heavier metals from the tap water. It is fascinating, but it removes everything from the water, like all the essential minerals that feed the animals and plants. However, it is possible that you can overcome it with remineralizing buffers.

Can goldfish live in well water?

In some regions, well water can make the best use of your tank. Sometimes, it is not recommended to use this kind of water because it is unknown how many bacteria or metals are contained. The risks exist. Even when you’ve heard of successful water use, knowing that a well is completely different from another is essential. Test your well water before using it.

Leave water out

Another option that some people select is to keep water in an open container. It takes an average of 24 hours for some compounds (such as chlorine) to volatilize from the water.

If you use water with harmful chemicals and heavy metal content (and leave it untreated), your Goldfish may never survive. Never risk it. If you don’t know if the tap water is safe to fish, you must eliminate chlorine disinfectants or heavy metals in the water.

Can I use well water for goldfish?

Occasionally a person with good water in their home area might use mineral water to fill a fish tank with Goldfish. Well water also could contain heavy metals and other toxins that kill fish in minimal quantities. Well water also may have several fertilizers. When we use healthy water, it must be clean and fresh, without chemicals or chlorine.

How do you make tap water safe for Goldfish?

A serious problem when using tap water for fish tanks is that the water in most places will contain chloramine.

Municipal tap water

How can I quickly get the fish into the water by turning on a faucet? When drinking water from the municipal network, the water underwent physical and chemical treatments to clean and remove most bacteria. The water quality is still variable based on the area. Occasionally water is filled with minerals like iron, fluor, and magnesium. Some tap water contains ammonium and organic matter, irritating delicate aquatic animals. One of the problems with using public water for fish tanks is the high content of chlorine which is frequently used in public drinking water systems.


Using rainwater in aquariums is an easy way to conserve money. Rainwater has a relatively low minerals content, which makes its pH fluctuate. Also, you must test and treat rain waters to ensure that they do not cause damage to your fish. Rains are also susceptible to contaminators in the air. Raindrops can absorb pollutants as they drop. Water that falls on a rooftop before collection may also collect toxic things from the shingles.

How to Care For Your Fish Bowl: A Beginner’s Guide

How to Care for Your Fish Bowl

Let’s get you started with fish-keeping with confidence by learning the basic steps and essential care tips on how to care for your fish bowl in this beginner’s guide.

Many hobbyists would consider a bowl a cheaper alternative to a glass aquarium. Indeed, these fish are not always healthy or allow a suitable habitat, especially tropical fish when kept in small closed habitats.

Let’s find out why they don’t provide an appropriate environment for fishing in your home. For more details on how to care for your fish bowl, keep reading this post where we’ll talk about fish that live in unfiltered tanks.

How to care for your fish bowl – What you need to know.

If you need to keep your fish in a bowl, try to provide a minimum size of 10-gallon containers so the fish can live better.

Lastly, one can use a sponge filter and some live plants to aid in the filtration and general water conditions. The sponge filter provides a place for beneficial bacteria to grow; it will also help aerate and move the air around the water, and living plants will help eliminate some nitrate in your body.

Small heaters can be used in a bowl, and Water temperature is an important parameter to keep an eye on your fish tank because of the constant fluctuations.

How to Care for Your Fish Bowl

Fishbowls restrict oxygen levels.

Food waste, clogged filters, and excessive algae growth can cause decreased dissolved oxygen and reduced gas transport capacity to the aquarium. In bowls, it is necessary to consider a limit to a gallon of water.

Not all fish species will adapt to space. Maintenance is easy; carry out water changes periodically to ensure that the fish’s oxygen levels are correct. The most suitable way to maintain the levels correctly is to have an air pump.

Betta fish can live in a fishbowl without a filter.

Bettas are the most popular aquarium animals that can live in a fish bowl without filter. Bettas come equipped with labyrinthine organs that allow them to breathe atmospheric air.

It is still necessary to maintain the purity of the water bowl. It is vital to keep a good filter and have good conditions for water. Typically, partial water changes should be done at least every five days. Betta fish, the Siamese fighting fish, lives in an ideal habitat for up to four years.

A few logs, the proper lighting, and the burrows keep your fish healthy in a bowl. Bettas like aquarium plants, so add plants to your fish bowls.

The limitation fish bowl fish

Fishbowls are best suited for the minimalist setup (this means we don’t use filters and heaters). Also, since you are using bowls, you only have a small water volume, typically 10 gallons maximum.

You must make up for the lack of filters and heaters with regular cleaning, changes, and monitoring of the water conditions. We suggest starting a setup if you have some experience in fishkeeping.

The water in the fishbowl will require regular changes instead of traditional cleaning of filters and so on.

The result is that you make up for the lack of filtration and heating by continually changing the water in the bowl. But this doesn’t allow you many species of fish in a gallon bowl.

Zebra Danios fish can live in a bowl.

Zebra Danios are gray with gold color and five blue stripes. They typically prefer temperatures in the 77 – 95°F range. Zebra danios should be kept in a minimum of three gallons of water.

Sand and gravel would be ideal substrates based on them, as fish prefer more alkaline materials. Plants like Amazon sword plants or java ferns increase the oxygen in the aquarium water.

You’ll need several of them and can opt for a 10-gallon fishbowl for a school of danio. The maximum size fish should reach about 2 inches.

Can Ember Tetras fish live in a bowl?

The Ember Tetra is also known as an incandescent tetra for its coloration. In nature, the tetra-ember swims in swamps and slow-moving rivers.

The fish will bloom in the bowl. Add floating plants, such as the hornwort and java moss, as well as java ferns, to the bain-marie.

Similar to other small fish, it is possible to overfeed your tetra and have water damage. Consistent water replenishment is key to having a tetra bowl. Tetras are sensitive to changes in pH, ambient lighting, and temperature.

Fishbowls are not easier to maintain

Some believe that a small bowl is easier to maintain than an aquarium. This is not the case. Fish bowls, especially if they are over stocked with fish require high maintenance.

As many knowledgeable aquarium traders will likely tell you, the vast majority of attempts to keep fish in a bowl can end in either one of two ways: one keeper quickly finds the bowl too tricky to maintain and upgrade to a traditional aquarium. The bowl is too small to keep, so keepers often find it too difficult to control.

How often do you change the water in a bowl?

Knowing how to care for your fish bowl requires an understanding of water parameters and the need for regular water changes. Partial changes should take place weekly, preventing the water parameters from becoming critical for fishbowls. There are products that can be bought and added to the system to condition the water.

That is why betta fish or danios are often recommended, as they are the best fish in these bowel conditions, as partial changes can be made once a week.

These fish deal well with poor filtration, as they are resistant, but it is necessary to change the water at least once a week.

Best fish bowl fish: guppies live in a bowl without a filter

Guppies are good to live in a bowl. Of course, the water change maintenance should be constant, but the concern will be far less than with other types of fish.

The guppy is the easiest fish available to hobbyists and beginners. These beautiful fish are available in fantastic color varieties and they are pretty hardy.

Guppies also reproduce quickly and accept fish food very easily. These fish are resistant to water parameters and when there are fry, they can be kept at an initial stage in a 5-gallon bowl.

The best fish to keep in a fishbowl

White Cloud Minnows are small but active fish with small red tips and like to swim in schools. They are super strong and very healthy fish that can live in not the best water quality.

They can survive without heat, so they’re not a problem unless it’s not necessary. Adding snails or shrimp does not affect the life of the fish.

You could keep three tiny fish in a 10-gallon bowl of live plants, and it would look fantastic. They are friendly and peaceful fish, so add some snails and shrimp to your bowl.

How to Care for Your Fish Bowl

Final Thoughts – How to Care For Your Fish Bowl

Ammonia and other substances like nitrite quickly accumulate in smaller spaces and poison fish. An aquarium can be maintained with weekly water changes and the installation of a sponge or air pump.

These pets can feel safe among plants like Java Fern, Anubias, and Java Moss, which is beneficial to water quality. In this article, we concluded that several fish species could live in a bowl, but it is not recommended to keep them that way. Ideally, in emergency cases, use this system.

What Fish Can Live With Goldfish? – 10 Best Goldfish Tank Mates List

What Fish Can Live With Goldfish? – 10 Best Goldfish Tank Mates List

What Fish Can Live With Goldfish?: Finding a suitable aquarium companion for a goldfish is possible, but you can’t just add a species!

There are some very important things to consider.

First, any fish added to the tank must thrive in the same environment as the goldfish, especially at water temperatures of 65ºF to 75ºF.

It is equally important that the fish get along with each other. What does that mean exactly?

A few things: The new fish will not harm the gold fish, the gold fish cannot eat the new fish, and the goldfish still has the space it needs to grow.

Each type of fish has different needs. For example, some fish like warm water, others like cold water, others like salty water, others do not. Since you want all of your fish to be healthy and happy, it is important to choose tankmates who like similar conditions.


What Fish Can Live With Goldfish?

10 Best Goldfish Tank Mates List


1. Other Goldfish

Adding another gold fish of the same size and type is one of the easiest ways to add another fish to your fish tank.

Keep in mind that goldfish are omnivores and can be predators. It is important that the tank mates are coordinated uniformly.

Be very careful with the size. Large goldfish eat smaller ones, so they must be the same size.

Also, fancy goldfish tend to move slower than common ones and are unlikely to compete for food.


2. Bristlenose Pleco

Bristlenose’s plecos are much smaller than common plecos, which can grow up to 15 inches. Therefore, the bristle plecos fall into a useful sweet spot that is small enough to fit in many goldfish aquariums without being so small that the goldfish can eat them.

Choosing a pleco that lives with your goldfish also has a great advantage: the plecos like to eat seaweed so that your tank stays nice and clean!

And while some plecos are known to suck on goldfish scales, which often leads to serious injury, this problem is rarely reported with Bristlenose Pleco.


3. White Cloud Mountain Minnows

The main reason White Cloud Mountain Minnows goes well with goldfish is that they are cold-water fish that perform well in the same environment as goldfish.

They pick fish and they don’t do well on their own, so you should add at least 3, although 6 is better.

White Cloud Mountain Minnows are also very fast and can generally flood gold fish, making them less likely to hunt.


4. Black Skirt Tetra

Advantages of keeping Black Rock Tetras with goldfish:

Black Skirt Tetras are robust and easy to care for.

They are fast and can reach goldfish if necessary.

Like the Platy, Black Skirt Tetras are usually too big for goldfish to try to eat.

Disadvantages of storing Black Rock Tetras with goldfish:

You need space in your goldfish tank for a school with six or more black rock tetras.

They are not always the most alive fish.

There is a certain risk that Black Skirt Tetra’s gold fish fins may get caught.


5. Rosy Barbs

Pink spikes like the same type of water as goldfish. They also become 4-6 inches long, so they also fit the size well.

They are not aggressive fish and leave their gold fish alone. They are too big for you to eat your gold fish.

Remember that pink spikes train fish and are very stressed when alone or in small groups. They must be kept in groups of at least 6.


6. Bloodfin Tetra

Advantages of storing Bloodfin Tetras with goldfish:

Bloodfin tetras are robust, very good for beginners.

They are also fast and can beat goldfish if need be.

Disadvantages of keeping Bloodfin Tetras with goldfish:

You need enough space in your fish tank for a school with at least 5 Bloodfin Tetras.

There is a certain risk that Bloodfin Tetras will suffocate goldfish.

At just over 5 cm, the Bloodfin Tetras are large enough to live safely with goldfish.


7. Rubbernose and Bristlenose Plecos

Both the rubber tip and bristle tip make excellent tankmates for a goldfish. Plecos are calm fish that generally leave your gold fish alone.

You spend most of the day eating rock and grass algae, which also helps keep your tank clean.


8. Checker Barb

Benefits of keeping tabs with gold fish:

The spikes are a calm fish that pairs well with community tanks.

They are fast, so elegant goldfish that tend to be slow swimmers can overflow.

Disadvantages of keeping concealer picks with goldfish:

Checkered spikes are big enough to live safely with goldfish. Therefore, there is a certain risk that larger goldfish will try to eat spikes.

You not only need space for one, but also for a Checker Barbs school.


9. Weather or Dojo Loaches

Weather loaches or dojo loaches are another great option as they are cold water fish that thrive in the same environment.

These loaches should be kept in groups of 3 or more and enjoy building. Therefore, make sure that they are covered with fine gravel or sand substrate.

The loaches also take up a lot of space by themselves, so you’ll need a fairly large tank to house them with goldfish.


10. Corydoras Catfish

Benefits of keeping Corydoras catfish with goldfish:

Corydoras chases food debris down the tank and eats it instead of letting it rot, which helps keep the tank clean

They are very peaceful and will certainly not cause any problems for your goldfish. The opposite does not necessarily have to be the case.

Disadvantages of keeping Corydoras catfish with goldfish:

Since your corydoras live at the bottom of the tank, you may have a hard time feeding them without your goldfish searching for food first.

Corydoras are school fish, so you need space to keep a small group.

As with other smaller fish on this list, there is a chance that goldfish will try to eat them.


How many fish can I add to a goldfish bowl?

So once you have a tank big enough for your goldfish, you’re probably ready to add your tankmates.

Overcrowding has many serious health effects. The more fish you have, the faster the water quality will decrease. Fish also become aggressive when overcrowded, causing injury and possible infection.

The amount of fish you can add to a goldfish tank depends on the type of fish. It’s best to spend time examining the fish you want to add to determine how much space they need.

It is a good idea to follow the rule of how much space your goldfish needs and then add additional gallons to accommodate the additional fish. Why?

Since the goldfish is quite a messy fish, overcrowding quickly leads to dirty water.

Carefully research the type of fish you want to add and make sure they have the space they need. If you choose a school fish, be sure to add enough to make it happy in your new home.



Building a community tank around a gold fish is not easy, but with careful planning, you can. A carefully planned combination of fish in the right environment can lead to a successful aquarium that is fun to watch.

The most important thing is that you use a tank that is big enough for all your fish to thrive. Remember that goldfish need a lot of space for them. If you keep them in a tank that is too small, they will hamper their growth and shorten their life.

How to Choose a Goldfish Tank?

There’s a lot more to choosing a best goldfish tank than meets the eye. Here are some things to consider when choosing one.

Goldfish Tank Size

As we said, goldfish can live for a long time. In order for them to reach their full maturity potential, the right tank is essential.

Since goldfish grow very quickly, it is best to start with a larger tank so you don’t have to keep updating.

What’s an ideal size?

Opt for 20 gallons for one or two goldfish. There are a few reasons to have a tank of this size.

Large aquariums are easier to keep clear, especially if you only have one or two fish in them. That means less maintenance, fewer water changes, and a happier, calmer goldfish.


Goldfish are very sensitive to temperature which is why water changes can be so stressful. Not only that, but the larger the tank, the less sensitive the water is to changes in ambient temperature.

Here’s the thing, goldfish are meant to be pretty big. If their surroundings were unobstructed, they could grow to more than 25 cm in length. Keeping them in a small container that inhibits their growth prevents their body from developing properly.

Goldfish can also live for a long time. If their growth is stunted, they usually only live a few years. Believe it or not, goldfish can live up to 20 years in the right conditions.

Goldfish grow very quickly and can be very heavy. As a result, they consume a lot of oxygen, so a large tank with a lot of surface is essential for their well-being.

Another reason having a large tank is a good idea is because goldfish are pretty messy. They are large and generate a lot of waste. Having more water dilutes the waste, affecting the quality of the water much more slowly than in a small tank.

Another thing to consider is whether you want more than one goldfish. They are a social species and enjoy company. That said, more fish means a bigger tank. You need to add 10 gallons of water to the tank size for each additional fish.

As for the shape, keep in mind that more surface area is better. Rectangular tanks are the best shape for this. Also, your goldfish will love to swim the length of the tank instead of swimming up and down. Avoid tanks that are too deep or oddly shaped.

Acrylic vs Glass

There are advantages and disadvantages to both glass and acrylic so the choice is up to you.


Acrylic aquariums are very light. They are easier to lift, making acrylic a good choice for large tanks as you should be able to lift them without assistance. They are generally easier to transport and move.

Another big advantage of acrylic is that it is slightly more forgiving than glass. If you have children in your home this is particularly important. They can withstand a minor impact or impact without cracking or breaking.

The bonding process used to make acrylic trays is quite impressive. They probably won’t leak and hold up very well over time. The seams are often so well done that they are practically invisible, making the view of your tank more spectacular.

Temperature is another thing to consider. Acrylic retains heat better than glass, so there will be fewer and fewer extreme temperature fluctuations.


Glass aquariums do not scratch, but they are more susceptible to cracks and breakage. They also hold their shape, whereas an acrylic tank can bend or warp over time.

While acrylic tanks look great at first, they can yellow or cloud over time if exposed to too much sunlight. On the other hand, the glass will never cloud or discolor no matter how long it is in the sun.

Glass is heavy and impractical for large tanks of, say, 200 gallons. It’s too much to lift and can really strain the stand or even the floor.

Another thing to think about is that glass usually only comes in ordinary forms. That said, rectangular tanks are best suited for goldfish, so this is still a suitable option.



Contrary to popular belief, goldfish don’t really thrive in a small bowl. In fact, they need a much larger tank to grow to their fullest potential and live long and healthy lives.

Our top pick for the best goldfish tank is the SeaClear Acrylic Aquarium Combo. It is a beautiful tank that looks perfect and crystal clear, giving you an ideal view of your pet. Plus it is really strong, lightweight and leak proof.

We also like that it is a small set that includes the tank and a lamp. This way you can still take the time to do your research and choose the filter you want to use.
