Top 10 Best Betta Fish Tanks – [2023] Reviews & Buyers Guide

ot haveLooking for the Best Betta Fish Tanks? Known for their vibrant colors and spectacular fins, Bettas deserve a quality home.

Then you have come to the right place! Betta fish are incredibly beautiful freshwater fish. Contrary to what is seen in many pet stores, they are not best served in a small aquarium. They need their own space to thrive. With the right aquarium, you can build a very affordable, small and thriving environment for your beta fish.

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.

Filtration

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.

Aesthetic

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.

Price

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.

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.

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.

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.

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.

Benefits

  • Can provide three stage filter canister filtration without being over the top in smaller Betta tanks

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.

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.

Benefits

  • 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.

Cons

  • 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.

Benefits

  • 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.

Cons

  • 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.

 

FREQUENTLY ASKED QUESTIONS ABOUT THE BETTA FILTER

HOW OFTEN SHOULD YOU CLEAN IT?

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.

ARE SPONGE FILTERS GOOD?

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. .

DO FILTERS DAMAGE BETTAS?

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.

CAN BETTAS LIVE IN A BOWL WITHOUT A FILTER?

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.

 

Conclusion

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.
