Many pet stores make it seem like you can buy a betta fish, throw it in a bowl and feed it every now and then for a healthy fish.

The reality is that bettas need tanks of at least 2.5 gallons with frequent water changes, and tap water can kill them because it contains toxic chemicals like chlorine and ammonia.

That’s where the water conditioner comes in. Add a few drops (actual dosage varies, so read the label) of the water conditioner to the tap water before adding it to your betta tank for the first time or after a water change.

This will help protect your betta fish from harmful chemicals found in tap water and will keep them healthy and happy for years to come. With so many products to choose from, how do you know which one is the best Betta water conditioner?

So how do you choose the best Betta water conditioner for your tank? It’s not as hard as it seems! There are just a few details to keep in mind, and in this quick guide, I’ll break them down and teach you how to pick the perfect product for your tank.

Not only have I looked at the best options, I’ve also compared them all so that you get not only the most effective, but also the best betta water conditioner that lasts the longest.

The 9 Best Betta Water Conditioner for Betta Fish Tanks

Best Betta Water Conditioner Reviews

1. Tetra BettaSafe Water Conditioner

Best Betta Water Conditioner

When used as directed with other beta fish care best practices, this is a great product for making tap water safe for your fish.

Detoxifies ammonia and neutralizes chemicals such as chlorine, chloramines and heavy metals to create an ideal environment for your fish. Plus, it adds a protective mucus layer to your betta, helping it fight off disease and parasites.

This product will leave your aquarium clean and your fish healthy and happy. It’s more concentrated than other water conditioners, meaning you need to use less and still get great results.

Although it is marketed for use with bettas, it can be used for all tropical fish, which is an advantage if you have other tanks of fish in addition to bettas.

Tetra has been a trusted name in seafood for decades, so you can rely on them to make quality products for all your seafood needs.

2. Aqueon Betta Bowl Plus Water Conditioner & Dechlorinator

Best Betta Water Conditioner

Specially designed for small tanks without filter systems, this is a pretty good value for a water conditioner. Many reviews say that this product works well, but it is not as good as other products, and the small bottle is only suitable for occasional water changes in very small bowls or tanks.

Not only does this product make tap water safe for bettas, it also contains trace elements that promote good health, bright colors, and natural protection against mucous membranes. This water conditioner is made in the USA, so you don’t have to worry about contamination from a poorly supervised China factory.

Overall, this is a good product, but it’s not necessarily the best value. Other products offer the same benefits but are more profitable.

3. Zoo Med Betta H2O Conditioner

Best Betta Water Conditioner

This water conditioner is more concentrated than other brands, so you will need to use less each time you change your betta water. It works immediately to detoxify nitrites and other heavy metals, while also relieving stress and promoting healing.

It comes in a handy dropper bottle, which is easier to use than trying to measure small measuring spoons. It is a bit more expensive than other water conditioners, but it can still be a good value because it is more concentrated than other brands.

4. API Splendid Betta Complete Water Conditioner

Best Betta Water Conditioner

This product helps prevent gill destruction, tissue irritation and fish kill. Contains aloe vera and tea tree oil to help heal fish and reduce inflammation. Aloe vera and tea tree oil distinguish API products from others. These natural ingredients can help your betta fish thrive.

Since the instructions for this formula specify how many drops to use per small unit of water, it is easier to use in smaller tanks than products that require a certain number of scoops per gallon. It has a great value and can be used for all tropical fish.

5. API Stress Coat Water Conditioner

Best Betta Water Conditioner

API Stress Coat was my favorite water conditioner for many years and is still something I always have on hand. Like the other products on the list, it removes chlorine, chloramines and heavy metals from tap water. It was also the first product to contain aloe vera and minerals to help maintain a healthy mucus layer.

Even if you don’t use it for routine maintenance, Stress Coat comes in handy if you have a sick or injured beta fish. It is safe to use between water changes and if your fish is not feeling well you can use a double dose of this conditioner to help them recover. I always use this to condition my hospital and grow tanks.

6. Seachem Prime Fresh and Saltwater Conditioner

There’s a reason Seachem Prime is the product that so many expert fish breeders rely on for their aquarium maintenance. Quickly removes chlorine and chloramine from tap water. It also binds nitrites and toxic ammonia for up to 48 hours, allowing your filter to remove them from your aquarium. This is my favorite general purpose product!

The highly concentrated formula is perfect for treating a wide variety of tank sizes and is especially useful if you have a 50 gallon or larger tank. But it’s not hard to measure a few drops per gallon for betta bowls and small tanks. Since it also attacks ammonia, this is a great option to use between water changes.

7. Seachem Betta Basics

Another option from Seachem is their Betta Basics formula. Specially designed for small betta fish containers and nano tanks, Basics is a buffered conditioner that helps keep the water neutral (pH 7.0). It removes chlorine and chloramines and detoxifies ammonia that builds up between water changes.

The bottle makes it easy to handle small amounts of water, even less than a gallon if you do a 10% water change in a nano tank. The formulation is much more dilute than Seachem Prime. That said, this product can be toxic to invertebrates, so don’t use it if you have small shrimp in the tank with your betta fish.

8. API Betta Water Conditioner

API is known for its high quality aquarium products and the Betta Water conditioner is no exception. It is specially designed for bettas and quickly removes chlorine, chloramines and heavy metals from your aquarium. The patented formula stimulates the formation of the slime layer of your betta fish and helps keep it healthy.

API Betta Conditioner is a perfectly diluted formula for dosing aquariums. However, it is a little too thin to use in bowls larger than 5 gallons. You would have to use too much product to make it profitable. If you have a small bowl for betta fish and you change the water regularly, this could be a good option for you.

9. Zoo Med Betta H2O Conditioner

If you have a small betta aquarium and want a conditioner that is very easy to use, check out Zoo Med Betta H2O. This formula is ideal for aquariums and small aquariums.

What is the Best Water Conditioner for Betta Fish?

Tetra Betta Safe is the best water conditioner for betta fish. It neutralizes ammonia, chlorine, chloramine and heavy metals while adding a protective layer of sludge to your betta. It is more concentrated than other water conditioners, so you end up using less of it.

This product keeps fish healthy and tanks clean. Tetra has been a top and trusted name in seafood for decades, so you know they have quality products. Many customers love how great this product is.


How to Use the Betta Water Conditioner?

Tap water contains chemicals that are harmful to betta fish and distilled water lacks beneficial minerals for betta fish.

Every time you add water to your betta aquarium and every time you clean the tank and replace all the water, you should add a water conditioner to the tap water to prepare the water so that it is safe for your betta fish.

In general, you want the water to be at room temperature before adding it to your beta aquarium. It is best to prepare fresh water for your betta aquarium for a few hours or even overnight before adding it to the aquarium so that it can warm up or cool down to room temperature before adding it to your aquarium.

Fill a large pitcher or bowl with the amount of water you want to add to the aquarium and add water conditioner according to the directions on the bottle. Many formulas suggest adding ½ teaspoon of water conditioner per gallon of water, but directions vary from product to product.

Before adding the new water to your betta fish’s tank or tank, fill a small tank with “old” water from the tank. Carefully scoop your betta fish out of the tank with a small net and place it in the container filled with “old” water, then remove the desired amount of water from the tank and add the new conditioned water.

When it’s time to change all the water and clean the tank, make sure to rinse the gravel, tank and any decorations with very hot water but NO SOAP. Soap scum, which can kill your betta fish, is nearly impossible to rinse off completely. After you put the gravel and decorations back in the tank, let them cool before adding the new water.

For best results, use a thermometer after adding the new water to the tank to make sure it matches the temperature of the “old” water your betta is in.

Now you can gently lift your beta fish with a small fishing net and return it to your tank with the cool, conditioned water.


How Much Water Conditioner for Betta Fish?

Each formulation includes instructions on how much water conditioner to add for best results. Typical instructions are to add 8 drops of water conditioner per gallon of water, 16 drops per gallon of water, and half a teaspoon per gallon of water, but always check the package for the instructions for that product, as some products are more or less diluted than others.

Adding too much of a more concentrated formulation or too little of a more dilute solution can kill your fish.



Adding water conditioner to your best betta fish’s aquarium is a critical part of keeping it alive and healthy. You should use a water conditioner every time you add water to your betta aquarium.

On average, you should change 25% of the water in your betta aquarium at least once a week and all the water about once a month. Smaller tanks require more frequent water changes because they usually don’t have filters to clean the water, and larger tanks will change water less often because dirt is more easily drained and can be captured through the use of water filters.

Keeping your beta fish water clean and conditioned is a critical part of keeping your fish alive, healthy, happy, and active. Tanks that aren’t cleaned often are a common source of sick fish, so when in doubt, change the water more often and follow the directions on the water conditioner bottle to make sure you’re using it correctly.

With a little work and the Best betta water conditioner, your betta can live many healthy years.

Not many fish are as colorful and beautiful as betta fish. Also, not many fish are as picky as they are. However, their beauty is worth it!

Understanding betta fish needs

One of the interesting features of betta fish is how easily they can become irritated when placed in the same tank with other fish. They don’t like “roommates” very much and should stay alone.

That is why it is important to find a different type of aquarium for your betta fish, as opposed to the usual tanks used for other fish. To help you choose a tank more easily, here I’ve shortlisted the Best Betta Fish Tanks on the market right now.

You need an aquarium that can meet your needs. So what kind of aquarium is that?

Fortunately, I’ve done quite a bit of research and come up with some suggestions that will keep your Betta happy and healthy.

Bettas are bright, colorful fish that are easy to care for and perfect for beginners.

What Is The Best Tank For A Betta Fish

Best Betta Fish Tanks

I have searched and reviewed a lot of aquariums for your beta fish. There are hundreds of aquariums available to purchase online. How did we decide what was best? It boiled down to the following criteria.

Size of the aquarium

Despite my research and experience in fish farming (over 25 years and still), the best aquarium size for a Betta is a 5 gallon tank. Anything smaller is too little space and is detrimental to your Betta’s long-term health. Anything larger is too much room for a single betta. Our focus in this review is the ideal aquariums for a single Betta. An aquarium kit is also preferred.


I want a complete aquarium set. Ideally one that comes with a built-in filter unit. This makes maintenance easier.

To turn on

Ideally, I can find a lit aquarium suitable for beginner aquarium plants. Having plants in our aquarium will not only make it more comfortable for our betta, but also healthier as the plants filter our nutrients in our water. Today, LED lighting is the way to go. If the lamp is part of a lid, that is an advantage for me.


You want your Betta tank to look good and n the gear showing up all over the tank. It needs to look good on a desk, cabinet or counter and have a lid to avoid evaporation problems and fish jumping out.


I don’t want this Betta tank to break your bank. It has to be well priced, but at the same time it has to be cheaply priced. If it’s cheap and offers me crap I won’t include it on this list!

What are the ideal best betta fish tanks?

This question is really hard to answer. There are many answers to this question depending on you and your betta fishing credentials. How old is your betta fish? What does he or she like?

We know one thing is for sure – betta fish should be kept alone and not with other fish as they would fight and most likely kill each other. But besides that, every betta fish is different and they all like different things.

If you already have experience with your fishing it is easy to see. If you haven’t, you may have to do some testing and fail before you can choose the most comfortable tank for your fish.

Some betta fish are very energetic; they would like to have a little more space in their tank for swimming and there may be more decorations to play with and hide too. Others like to live their lives calmly; these would not require that much space.

In addition to the fish’s needs, you must also consider its tastes and desires. Would you like a small tank for our desk? If so, how small? How big? Do you mind installing cables and electronics manually, or do you want them all pre-wired to save time and effort? Do you care if the lights are one color or do you prefer the colorful multi-colored LED lighting system?

The answer to each of these questions is an important factor in the overall decision you make in selecting from our reviews of best betta fish tanks.

What temperature is best for the Betta fish tank?

Most betta fish tanks, even the one that claims to have a complete starter kit, do not include a heater. This will not be a problem if you live in a warm area throughout the year. However, it is a big concern if you live in places that have temperature changes during the winter.

Betta fish are originally tropical fish. They prefer warm water. The temperature in your tanks should never drop below 74 ° F (approximately 23.5 ° C). The ideal temperature is within the range of 78 ° F and 80 ° F (approximately 25.5 and 26.5 ° C).

Due to the demand for betta fish at high temperatures and if you live in places that have a cold winter, getting a heater for your tank is absolutely essential to keep your fish warm, healthy and happy all year long.

How to set up a Betta fish tank?

The way to set up a betta fish tank varies depending on the type of fish tank you have. Most of the time, the tank and its kit will come with a complete and clear set of instructions for everyone to follow easily.

In general, setting up a tank for betta fish is not difficult because they are often small in size.

You need to set up and assemble the tank itself. After that, you put decorations and gravel all over the tank. Depending on how you want to do that, it can take anywhere from 10 minutes to hours to decorate your tank.

Then you need to carefully connect the electronic accessories, including filters and lights. As stated above, the tank does not come with a heater. However, you know that you need to get them sometimes, depending on the weather. Remember to set the most suitable temperature for the tank so that the fish can be happy.

Betta Feeding FAQs

How Much Should You Feed a Betta Fish?

How much your betta fish should eat at one meal really depends on the size of your pet. A betta’s eye is roughly the same size as its stomach, so fish with larger eyes and size can be fed more.

You can base this on trial and error. For example, if you find granules left over after a meal, try reducing the amount of food you put in the tank.

Another option is to try soaking dry pellets in a little water before placing them in the aquarium. This will prevent them from expanding so much inside your fish’s stomach and may help regulate their appetite.


How Often Should You Feed a Betta Fish?

Bettas need to eat once or twice a day. Adult bettas can usually survive on one meal, while babies or young fish that are still growing need 2 meals a day.

It’s important not to overfeed your betta fish. If you are not at home and are skipping an evening meal, it is better to skip it than to feed twice as much in the morning.

(This article answers the question: How often should you feed bettas bloodworms?)


What Happens When You Overfeed a Betta Fish?

One of the main problems that overeating can cause is constipation. Especially when using low-quality foods with fillers that are harder to digest.

If you notice that your fish’s belly is bloated, it’s stopped wasting, or lost its appetite, the problem is likely constipation. This has the potential to become something more serious, like a swim bladder disorder. The swim bladder is a part of your fish’s body that allows it to swim up and down in the water.

More on Betta diseases found here.


What to Feed Betta Fish When Out of Food?

A betta fish can eat pieces of tuna or shrimp, so long as they’re small and you remove uneaten pieces from the tank afterwards.

You can also feed your betta boiled peas, one at a time. Ensure that you peel off the skin and cut them into small pieces.


How to Feed a Betta Fish While on Vacation?

There are a few options for feeding your betta while on vacation.

First, you can always ask some one to look after your fish while you’re away. However, if you’re only gone for a few nights or a long weekend, your betta will be fine on their own until you come back.

Another good option is investing in an automatic feeder. This is the best way to leave your fish stress-free and a lot of automatic feeders are able to disperse food accurately without over or underfeeding.

Food blocks are another great option if you’re away less than a week, but don’t want to leave your fish without food. They are designed to float in water and dissolve slowly to release small amounts of food at a time.


How Long Can Betta Fish Go Without Food?

A betta can go without food for about 14 days, so if you are concerned that the fish is overeating, it is not a big deal to go without food for a day or two.

It can also take the stress off of small vacations too, knowing your bettas will be okay.


Final Thoughts

All the Best Betta Fish Foods we’ve mentioned here have been nutritionally formulated to help your fish thrive. All of our selections are nutritionally formulated for bettas and will help them live their best lives. Our most recommended foods would be protein packed meals that include krill, squid and fish, while still including green extracts for valid minerals.

Most people who own bettas keep them in unfiltered containers.

One of the reasons they are so popular is that they can survive in such conditions. They can live in stagnant water and apparently need little care.

The truth is, it can be difficult to keep your Betta fish in an aquarium without a filter. You need to make sure to keep the water clean by changing it weekly.

You also need to be very careful not to overfeed as food scraps can lead to many water quality issues. When something goes wrong in a bowl, it goes very quickly. Dirty water can lead to infections, fin damage and even premature death.

Just because they can live in a bowl doesn’t mean they should. The best place to keep a betta is in a container of warm, clean water where it will be happy and healthy. Using the best betta filter will ensure that your fish have an ideal environment in which to thrive.

Looking for the best filter for your betta aquarium? This guide explains how to select the filter that best suits your setup.

You will learn to choose one, the different options available and my favorite products for each category.

Ultimately, you know exactly what you need.

We hope this page tells you everything you need to know to find the right filter for your betta tank. If you already have a filter, we’d love to hear about the filter settings you made, so let us know in the comments.

This article is mainly about choosing a filter for a single betta tank. For larger setups, you may need to look for a slightly different filtration system, although most of the logic still applies.

If you want a little more information on how a filter works, check out our article on betta filtration, which contains diagrams, defines the terminology we use, and answers some frequently asked questions.


Does a Betta Fish Need a Filter?

Using a filter for Betta is the easiest way to give them a happy and healthy life.

A filter facilitates the growth of small ecosystems of various microorganisms that help break down waste in the water. While you should change the water in an aquarium every week, you shouldn’t really change the water in a filtered tank as this will interfere with beneficial microorganisms.

It is recommended to change about 1/3 of the water every week. This is far less work than a bowl requires.

When it comes to choosing a filter, Bettas do best with a filter that underperforms. It aids in oxygenation and cleaning, and the low pressure won’t put too much pressure on your betta.


The 10 Best Filters for Your Betta Fish Tank


1. Whisper In-Tank Filter with BioScrubber for aquariums

Best Betta Filters

This is a great filter made by Tetra that is great for a small aquarium up to 3, 4, 10 gallons, the perfect size for a Betta. Installation is easy as it is mounted in the tank using a hanger or two suction cups.

The filter in the tank has 2 advantages. The first is that you can push the tank against the wall because nothing is in the way. The second is that it is exceptionally quiet because the tank is submerged.

To keep the water as clean as possible, this filter uses 3-stage filtration.

First, a dense mesh traps large pieces of debris and debris. Next is the activated carbon filter that absorbs impurities, discoloration and odors.

The final stage is biofoam, where colonies of aerobic bacteria remove ammonia and nitrates before the water returns to the aquarium.

2. AquaClear Power Filter – 110V

Best Betta Filters

This filter provides a large amount of oxygen in the water column, so that your Betta does not have to extract oxygen from the water surface. Your water should stay very clear due to the amount of water it will clean every hour.

You will find this product to be cost effective as it provides the longest contact time between the water and the filter media.
A two-year warranty gives you the confidence to rely on the filtration capabilities. You should also come to appreciate the space in the media room that allows you to mix and match the media you can use.


  • This product provides more aeration in the water column.
  • It is able to clean a large amount of water for the size of the system.


  • More water will evaporate as this design will expose the water outside your tank top

3. Penn Plax Cascade Hang-on Aquarium Filter With Quad Filtration System

Best Betta Filters

This Penn Plax filter circulates 20 liters of water every hour and is perfect for a small tank up to 7 liters. It has a hanging design that simply slides over the edge of the glass in the tank.

There is a built-in leveling device to hold the filter in place and the inlet tube is extendable so you can place it close to the bottom of the tank if desired. Your Betta will love the adjustable flow rate that allows you to slow the filter down a bit during the meal.

In terms of filtration, this system uses replaceable filters that need to be replaced every 6 to 12 weeks. The first stage of filtration is the poly fiber yarn barrier to trap large pieces of dirt and debris.

The water then flows through the activated carbon to absorb any impurities that could discolor the water or cause a bad odor. There is also a home for the major microorganisms to colonize on this filter to provide the biological filtration you need to remove ammonia and nitrates.

These filters are made exactly for this machine. Replacing them is very easy and some filters are even included. Setup is simple and ready to go out of the box.

4. Zoo Med Nano 10 External Canister Filter, up to 10 Gallons


Best Betta Filters

This product should be a good choice for Betta keepers who want a canister filter for their smaller aquariums. The engine is separated from the filter media so you don’t have to worry about your engine intakes getting clogged.

The smaller container needs to be cleaned more often as the chamber and contents clog more quickly than larger container systems.
Operation is limited by design as this system is made to operate with minimal effort. The media chamber can be packed with any type of material you want to use for filtration purposes.


  • Can provide three stage filter canister filtration without being over the top in smaller Betta tanks
  • Suction of the filter at start-up is easy to do
  • Water supply hoses are located on the top of the unit


  • The design of this product is a bit heavy as it has a tapered base
  • The media room is smaller due to its more compact design, which can be a disadvantage for some aquarists.

5. Aqueon Quietflow Internal Power Filter

Best Betta Filters

Consider this Aqueon internal filter for a 10 gallon tank. The flow rate is 57 liters per hour and only uses a small replaceable cartridge. This is a fairly versatile filter.

It is internal and can be hung vertically as well as horizontally. In addition, the flow, direction and height of the water are adjustable.

This is great for Bettas as they don’t like overly turbulent water and they prefer a smooth flow.

There are 3 stages of filtration. The first is made of dense foam that traps all particles and dirt. Then there is activated charcoal to stop toxins, discoloration and odors. The last BioGrid phase in which ammonia and nitrates are removed by micro-organisms.

One more important thing to mention is that this filter comes with a limited lifetime warranty.

6. Fluval External Filter 106

Best Betta Filters

The Fluval 106 circulates 100 liters of water every hour, making it ideal for Betta tanks up to 25 liters. A strong seal ensures that the pressure builds up evenly and ensures a smooth flow of water through the medium used.

Fluval is one of the most popular filter systems due to its durable design and reputation for cleanliness in the market.
This filter is made of durable materials that you will enjoy for many years and is guaranteed by the manufacturer for three years. The drive paddle is damped allowing it to work quietly in any room.


  • An in-line strainer helps prevent this system from clogging during use
  • AquaStop valve helps prevent water from dripping when opened
  • Media baskets help keep materials separate while water flows through them


  • This system is priced higher than most of the other products on this list.

7. Deep Blue Professional ADB88700 Biomaxx Nano Filter for Aquarium

Best Betta Filters

Another great option if you’re looking for a pendant style filter is this one from Deep Blue Professional. Filters 16 liters per hour and is designed for small tanks up to 5.5 liters. That turns out to be a great size for a Betta tank.

This filter also allows you to adjust the flow rate and has an optional inlet extension tube so you can draw water from the bottom of the tank if desired.

This filter has a 2-stage system. The first is a mechanical polyfiber filter that catches dirt and coarse dirt. It is also the perfect place for biological colonies to grow, allowing microorganisms to eliminate harmful ammonia and nitrates.

8. Lefunpets Filter with Tetra Air Pump

Best Betta Filters

Sponge filters are simple single stage filter systems powered by an external air pump. They gently suck water through the sponge and physically filter debris before returning the water to the tank. Because they don’t use filter media, they don’t remove drugs or toxins such as ammonia. This sponge filter from Lefunpets is perfect for a 2.5-10 gallon betta tank. Provides a gentle stream as the water flows through the sponge and out of the tube at the top. The small sponge and tube will fit most tanks and even the largest betta bowls.

This sponge filter is located at the bottom of your tank and hooked to an air pump with a plastic hose. I recommend going with Tetra’s very quiet Whisper Pump. Unlike many other lesser quality air pumps, the Tetra is designed to minimize vibration and is truly one of the quietest I have ever used. You’ll need some tubing to match your filter and air pump, so I’d consider this 25-foot length from Penn Plax. You can easily cut it to size and it is always useful to have extra pipes on hand for adjustments.

Sponge filters are one of the least expensive options and come in a variety of shapes and designs. If the Lefunpets filter isn’t quite your style, consider this corner box filter. It is similar to a sponge filter, but also has a compartment for the growth of colonies of good aquarium bacteria. However, it is not suitable for raising young birds.


  • Inexpensive installation that is easy to adapt to almost any tank size or style, including betta bowls.
  • Ideal for raising young fry and for short quarantines or hospital tanks.
  • Provides the ideal smooth flow rate that betta fish prefer.


  • The single-phase filter does not remove toxins from the water, only physical waste.
  • This setting requires weekly maintenance and water changes to prevent the filter from clogging.
  • The air pump may be too noisy for a bedroom Betta tank.

9. Marina Power Filter

Best Betta Filters

This Marina Power Filter is a hanging filter with a compact design that is perfect for aquariums up to 10 liters. Installation is really easy, you don’t even need to prime it!

It is also a silent filter, because the motor is submerged in water. It has an adjustable flow so you can find the perfect speed for your betta. They also include a sieve sponge to prevent smaller bettas or other debris from entering the filter.

One of the reasons this is such a good filter is the cartridges. It comes in 2 different grades, Bio-Carb and Bio-Clear. Both contain Ceramitek, an extremely porous ceramic filter that provides enough space for biological filter organisms to thrive.

10. Aqueon 7.5 Gallon Aquarium Kit

Best Betta Filters

One of the easiest ways to set up a filtration system is to buy a tank that contains one. It may be a bit more expensive to buy an all-in-one Betta tank, but it will save you the trouble of choosing a filter style and figuring out how best to fit it into your tank.

The Aqueon 7.5 Gallon Aquarium Kit comes complete with the basic supplies you will need to set up your betta tank. It has a 2-stage soft filter with a filter pad and a replaceable carbon cartridge. What I like about this setup is how easy it is to access the filter.

You can check the filtration system from the top of your tank by lifting the lid, it’s that easy! This setup is an ideal choice for a beta fish and the filter is soft enough to also raise fingerlings and shrimp. At 7.5 liters you have enough space for an adult fish and decoration, and there is no reason why you cannot grow live plants in this tank.


  • The complete aquarium setup contains everything you need to start a betta aquarium.
  • The 2-stage filter removes dirt and cleans the water, reducing the frequency of water changes.
  • The filter is integrated in the hood and is easily accessible.


  • It may be more expensive to purchase a complete configuration.
  • Because the filter is built into the hood, the noise level can increase as the water evaporates.
  • The filter cannot be reused separately for other tanks as it is built into the aquarium.

What is the best Betta filter?

Your Betta will love all of these filters, but the Penn Plax pendant filter is the best. It is the perfect size as it works with tanks up to 7 pounds and installation is very easy. The built-in spirit level keeps the filter submerged.

If you have a Betta that is particularly skittish, this is a great option because of the adjustable flow rate. You can slow it down when it’s time to eat to avoid getting hit by an overcurrent.

This system uses all-in-one filter cartridges that are very easy to replace. Each lasts 6-12 weeks and provides the 3 major stages of filtration your Betta tank needs: mechanical, chemical and biological. You even get some filters to get you started, so you can set everything up right out of the box.

What kind of filter for Betta Tank?

While any filter is better than no filter, there are some features that a good Betta filter should have.

It should be easy to maintain and maintain, especially if you don’t want to spend too much time on maintenance. All-in-one filters are the easiest to use because you don’t have to do anything other than remove the old one and put in a new one.

A filter that is placed under water is quieter and ensures less movement through the tank. Hanging filters are good too. They are easy to install, but the backflow can cause a lot of ripples on the water surface.

Bettas naturally live in calm waters and don’t really care about water with too strong a current. An underwater motor and adjustable flow rate are two things that give you control over the flow so you can make the changes your Betta prefers.




Typically, you’ll want to clean your betta tank filter about every 10 days. However, you should never do this with tap water, hot water, or distilled water.

They should only be “cleaned” with your existing aquarium water to avoid killing the beneficial bacteria in them.


Some sponge filters are good, some are not. It really depends on the brand and build quality. If you choose foam or sponge filters, choose only those from companies you already know and trust, or who do veteran aquarists if you’re a newbie, or who have very high ratings from real users on sites like Amazon. .


In general, the filters do not harm the fish. However, the circumstances where this could be different are if you have vulnerable fins, such as bettas, with a filter that is too powerful for the environment.

Make sure to always adjust the size of your filter to the number of gallons of water in your aquarium.


Bettas should never live in an aquarium. They need at least 5 gallons of water per betta.

And technically, bettas can live in small aquariums without filters, but they will probably just survive if they do. Use filters to keep your home safe, pure and healthy throughout your life.



As you can see, choosing a filter for betta aquariums is not a difficult decision. It mainly comes down to which style you prefer and which suits your tank best. Adjusting your aquarium filter with a baffle or sponge filter over the inlet tube is usually an easy and affordable way to get almost any filter to work with your aquarium.

If you are still unsure which filter style to get for your aquarium, consider this final tip:

  • If you have a 10 gallon or larger tank, consider the best HOB filter, the Aqua Clear. You may need to adjust it for your setup, but it’s a great option for most larger betta tanks.
  • If noise is an issue then the best underwater filter, the Aqueon Quietflow, is a great option and very reasonably priced. It’s so quiet you might forget you even have a filtration system in your tank.
  • If you need a small filter for your betta bowl or tank, consider going for the Azoo Mignon which is rated as the best filter for nano tanks. It’s a good choice for 2.5 to 5 gallon tanks, and I love that it comes with an inlet sponge filter.
  • Having the best sponge filter configuration out there is never a bad idea if you need to install a hospital or quarantine tank. It is also a great option for all sizes of betta filter tanks. Since it is a 1-stage filter, you will still need to do weekly maintenance and water changes, but your beta fish will probably love it.

Hopefully my quick guide on betta filters has been informative and helpful to you in planning your tank. I’d love to hear your thoughts in the comments or tell us about the filtration system you use in your betta filter tank!

Getting the right stove shouldn’t be a problem as there are so many available today. In this guide, we will learn more about such stoves and their general benefits.

A tank heater is one of the most important pieces of equipment you will need to keep your betta fish healthy.

Bettas are adapted to tropical waters, which are usually slightly warmer than room temperature in your home.

You see, the temperature in your home is not as stable as the temperature in the natural environment of Betta; it fluctuates up and down depending on how hot or cold it is outside.

A tank heater can compensate for those differences by keeping your aquarium at a constant warm temperature.

But choosing the right heater for your betta fish can be challenging, especially since many inexpensive heaters in the market don’t perform as well as advertised. Today we’ll take a look at the features to consider in a betta fish warmer and discuss five of the best Tank Heater for your betta fish.

Talking about one of the most important devices you need to create a favorable environment for your betta fish and keep them healthy, the stove is a perfect example of this “important equipment”. In this piece, we’ll be sharing with you the 10 best Betta Tank Heater available today!


Does a Betta Fish Need a Heater?

To help answer this question, you must first know the importance of a heater. Well, the main reason is that fish can be a delicate species. By having the water at the right temperature, you can be sure they are safe.

It is not just about the right temperature, but also about a constant temperature. The fish does not have to be in water whose temperature continues to fluctuate.

In most cases the water temperature is affected by the air around the tank. Sometimes this can lead to fluctuating temperatures. To find out, you need to find the right betta tank heater.

Studies show that every time the water gets too cold, it affects the betta fish. They tend to remain inactive. In such a scenario you will see that they have trouble eating, swimming and that some may even die.

That said, you can also expect them to have some health complications if the water is too hot. That’s why you need to keep the water at the right temperature.


Ideal Water Temperature for Betta Fish Tank

So what’s the right temperature? For betta fish, it would be ideal to keep the water between 74 and 82 degrees Fahrenheit (23-28 degrees C). It is often recommended to buy heaters that do not overheat beyond this range to protect your fish.

It will be great if you also have a thermometer. This is because some boilers do not have a current temperature display. Having a thermometer is great for keeping an eye on the heat of the water.

Some also look at the boiler manufacturer’s rating. This helps a lot so you know what temperature the model can operate in before buying.

5. EHEIM Jager Aquarium Thermostat Heater (2nd Pick)

The EHEIM Jager Aquarium Thermostat Heater offers the same versatility as the Fluval E Heater, with a few key differences.

Most notably, this heater can withstand colder temperatures of up to 65 degrees, which is ideal if you live in a warmer environment where the purpose of the heater is primarily to keep the water temperature constant.

Like the Fluval E, the 300 watt version of this heater is suitable for tanks up to 100 gallons.

Note that this heater is significantly longer, at 20 inches, so your tank should be shaped to allow the heater to remain fully submerged. EHEIM also makes smaller versions of this tank heater up to 25 watts, which is suitable for small 5 gallon tanks.

The temperature control on this stove is easy to read and turn as it is located on the top of the unit. The temperature can be changed in 0.5 degree increments at a time for precise temperature control.

The stove has a simple light to indicate whether the stove is working or not. But unlike the Fluval E heater, there is no digital display of the current temperature in the tank. Therefore, you should keep a thermometer in the tank to monitor the temperature and check the tank for deviations from the set temperature.

However, when it comes to safety, this stove stands out. The heater will switch off automatically if the water in the tank becomes too low and a safety check prevents the heater from running dry.

The stove is also built shock-resistant and unbreakable. A supplied mounting bracket and a set of suction cups make it easy to place this heater anywhere in your aquarium.

6. Fluval M Submersible Heater

  • Available watts: 50-200
  • Tank size: 15-65 gallon
  • Temperature range: 66-86 degrees
  • Automatic shutdown: yes

This fully submersible heater from Fluval is a cheaper alternative to the E heater, although it loses many of the advanced features of the E heater, such as the LCD temperature display.

The stove has a limited temperature range of 66-86 degrees, so you may have to choose a more powerful stove if your house is often cold. The temperature can easily be changed in steps of 1 degree using the rotary knob on the top of the heater.

The stove is relatively easy to install. The heater comes with a simple mounting bracket with which you can place the heater anywhere and you can remove the heater from the tank without removing the bracket.

Better yet, Fluval has designed the heater to be completely shock resistant and while there is little protection from the hot center, your beta fish cannot make full contact with the heating elements.

Note that although this stove is relatively small, it is still 11 inches long. That means it doesn’t really fit many of Fluval tanks under 15 gallons, such as the EVO Reef 13.5 or the 9.5 gallon Flex tank. Therefore, you will need a relatively tall tank to use this heater and keep it completely submerged.

This sleek and efficient stove from Aqueon is designed for simplicity. The knob on the top of the stove is very easy to access and the temperature dial is large enough to read.

While you can only change the temperature from 68 to 88 degrees in 1 degree increments, that should be more than enough versatility for most betta tanks. The stove does not have a temperature reading, but there is an LED light to indicate when the stove is on.

The heating element in this stove is well protected so that it doesn’t endanger your betta fish, and the stove itself is designed to be nearly indestructible. The stove also has an automatic shut-off to turn it off in case it overheats, and it will automatically turn back on after it cools down.

A set of suction cups makes it easy to install this heater horizontally or vertically, but keep in mind that the 19-inch length of the heater requires you to have enough space in the tank.
