Bettas are colorful, brilliant fish that are easy to handle and make excellent starter pets. Most people believe that bettas prefer to live in small enclosed places like vases and bowls, but in reality, they prefer large tanks with much more open swimming space. 

Because of their often aggressive disposition, many people keep them alone, which is another reason why tiny tanks are so popular. While novelty fish tanks like as small bowls are available, we do not recommend keeping fish in these tanks since they are just too little.

It is not recommended to use less than five gallons. In this comprehensive introduction to betta fish tanks, we go over exactly what constitutes a good tank before going through the most popular tanks on the market right now.

#1 Overall Best: Fluval Edge Aquarium with LED Light

After plenty of research, we’ve found that the ultimate tank for your betta fish is the Fluval Edge Aquarium. While there are two sizes available, six and 12 gallons, we’ll be reviewing the six-gallon tank. 

Fluval is a popular name when it comes to fish products. They make filters, among other items to make your betta happy and healthy. This aquarium comes in a 3-D cube design that gives you 360-degree views of your aquatic friend. 

While there are plenty of tanks on the market, this one takes the top spot because of the crystal clear class design that is situated on top of a pedestal. This makes the tank look like it’s suspended in air, defying gravity. 

As the name suggests, there are LED lights included that have daylight and moonlight features. The white light setting is best used during the day and the blue should be turned on in the evening hours. 

Included with the aquarium is a filter with three water treatments to ensure your betta is swimming in clean and healthy water. Fish owners appreciate that the filter is hidden from view.

#2 Best for Small Spaces: Tetra LED Cube 3 Gallon Tank

We know how important it is to have a tank that’s at least five gallons but that’s not realistic for everyone. If you insist on having a smaller tank, consider the Tetra LED Cube 3 Gallon Tank. 

We chose this tank due to its unique design. Similar to our overall favorite choice, the cube design of this tank makes it appear as if it’s floating. Because of its smaller size, it is slightly more affordable, usually priced at around $40. 

There is a beautiful Moai head in the center of the tank that gives your Betta something to swim around. It comes with a filter that is hidden, so as not to disrupt the overall aesthetic of the aquarium. The filter provides three-stage filtration and is whisper quiet. 

Buyers appreciate the built-in LED light that hangs overhead. It’s made with a lower voltage that is energy-efficient, while still providing plenty of illumination for your viewing pleasure. It’s important to note that this Tetra tank doesn’t come with a heater, which could be seen as a downfall if you live in a colder state.

#4 Best for Aesthetics: Marineland Contour Glass Aquarium Kit

Last but not least, let’s talk about the Marineland Contour Glass Aquarium Kit. The primary fish tank is a bent glass tank, and the aquarium kit’s smooth form and hidden filtration system provide an all-encompassing and unobstructed view from every angle. 

It’s perfect for any table, from your kitchen to your workplace, thanks to its modest profile and beautiful foundation. For day and nighttime enjoyment, the aquarium kit includes an LED light with two settings: strong blue and white.

It comes with a transparent glass cover for illumination. For quick access to feed the fish, the cover may be pushed back over the filtering framework. It’s simple to remove allowing easy access to the water tank for cleaning and setup. The filtration system is beautifully hidden beneath the main fish tank.

This tank is powered by a filter pump that is both quiet and powerful enough to constantly circle the water. The pump’s flow can be adjusted, making it ideal for Bettas and other small fish who like a moderate flow of water.

There is nothing to complain about in terms of quality; the bulk of the necessary components are included, and all you need to complete your setup is a 7 1/2 watt tank heater and a few ornaments.

Choosing the Best: What to Look For

To make a suitable home for your fish, you’ll need to set up your fish tank and finish a full cycle, just like any other tank. 

It will also need a heater and a filter, which we’ll discuss in further detail later. 

Bettas prefer to hide and relax in a variety of places, so add living plants like Java Moss and Java Fern, as well as pebbles and tunnels. 

You have complete control over the substrate you choose; you may use sand or fine pebbles. Because the Bettas’ fins are so fragile, avoid any substrate with harsh sharp edges. Let’s take a look at the other things you’ll want to consider when buying a betta tank. 

Tank Size

Because they’re native to Asia’s gardens and shallow waterways, it’s a common misconception that they just require small tanks. One reason small bowls are undesirable is that you won’t be able to keep the water conditions consistent, allowing ammonia spikes to occur quickly. 

Putting your Betta in at least five gallons, or more if feasible, will give them additional swimming room as well as make your aquarium more aesthetically appealing. Bettas come in a variety of types, including the iconic Crowntail Betta, and many of them need plenty of space to swim around.  

Some species demand more room, so do your homework on the kind you intend to maintain. If you’re only keeping one, a 10-gallon tank is a good size. This gives them adequate space, the water quality should remain steady, and it will require less care than a smaller 5-gallon aquarium.

Filtration

Another widespread misunderstanding about housing Bettas stems from the assumption that because they live in shallow waters, the water must be unclean – and so they can withstand living in dirty tank water. 

This is incorrect; their native home is part of a big bio-diverse ecosystem, and the water is safe and highly oxygenated thanks to the presence of several plants. Bettas can breathe from the air. This permits them to leap from one pool of water to another until they reach a bigger body of water in their native environment.

Some individuals believe that it doesn’t matter how big their aquarium is as long as they can breathe. For them, breathing air should only be a transient remedy. 

They require an oxygen-rich atmosphere, which a filter will supply. If you don’t want to use a filter, ensure you do a partial water exchange of 40% of their tank water every few days. 

A concern with using a lot of filters is that they might generate a water flow that is too harsh for Bettas. Adding a sponge or a cloth to the output will immediately resolve this.

LED Lighting

Bettas are stunning fish, so you’ll want to be able to watch them any time you want. The best choice is to use bright LED illumination. They’re energy-efficient and help to highlight your Betta’s vibrant colors. 

Bettas require a consistent day and night cycle. Selecting a tank with daylight and moon lighting s a terrific method to keep your fish healthy while also allowing you to see it at all hours of the day and night.

Style

Because we all know how gorgeous Bettas are, you’ll want to honor your fish by keeping it in a similarly stunning tank. The greatest experience comes from having a tank with several unobstructed viewing angles. 

It’s critical to prioritize your fish’s health at all times. You should not choose a tank because it appears to just look cool. You must ensure that your Betta will be able to flourish in its new surroundings.

What Temperature is Best for Betta Fish Tank?

A heater is not included in most betta fish tanks, even those that claim to be a full beginner kit. If you live in a region that is warmer all year, this shouldn’t be an issue. But, if you live in an area where the temperature fluctuates during the winter, this is a major problem.

Betta fish are native to the tropics. They enjoy water that is warm. Their tanks can not be below 74 degrees Fahrenheit. The optimal temperature is between 78 and 80 degrees Fahrenheit. 

Since betta fish require a high level of warmth, particularly if you live in a cold climate, a heater for your tank is extremely essential to keep your fish comfortable, healthy, and content all year.

The Different Types of Betta Fish Tanks: Pros and Cons Compared

There are several types of fish tanks that can house Betta fish. Let’s take a deeper look at each of them, along with their advantages and downfalls. 

Freshwater Tropical Aquariums

Beginner fish keepers should feel quite comfortable starting with a freshwater tropical aquarium. With this style of tank, there are a few extra variables, but nothing too strenuous.

The temperature in freshwater tanks can range from 72 to 84 degrees Fahrenheit. This form of freshwater aquarium certainly has new difficulties that must be handled, such as heating and temperature range maintenance.

Breeder Tank

Breeder tanks are usually a little smaller and shallower than ordinary fish tanks. This is because, during spawning, the fish may need to swiftly reach the surface of the water, which they can accomplish readily in shallower water. 

They usually feature a covered filter to prevent the fish from being damaged by the filter while in the tank, as well as plastic “traps” that may be placed into the tank.

Vases and Cups

Betta fish may survive in small quantities of water, but they thrive in bigger containers. This enables individuals to swim longer distances, flex their muscles, and live a healthier lifestyle. 

Your fish don’t care about the design of the tank, but you should ensure there’s enough area for all of their demands. Although you may wish to aerate the tank, this is not a good idea for betta fish, which will be much happy and healthier if you only utilize a good filtering system.

Large Tanks

Fish tanks are often composed of acrylic or glass, but bigger ones are typically made of high-strength acrylic to resist the water pressure as well as all of the technology required to keep the tank running smoothly and the fish safe. 

Larger tanks, on the other hand, require more elements, such as lighting, filtration, and a heater, depending on the type of fish contained in the aquarium. Many big fish tanks include a cover that houses the lights while also preventing fish from leaping out. A huge fish tank provides ample space to create a complete ecosystem for the fish, including floor material, plants, and other objects for the fish to hide.

Verified Review: User Experience

There is a lot to consider when purchasing a fish tank for your betta. You’ll want to consider the features listed above and ensure they have plenty of room to swim around. An Amazon user has this to say about our top choice, the Fluval Chi II Aquarium:

“It’s a beautiful tank. The filter works well. The fountain is a nice feature. I was worried about putting a betta fish in here because they’re top swimmers, but there is plenty of room around the filter and the filter flow is gentle. The light and filter are connected. You can’t turn the light on and the filter off, but there is a light switch on the back of the filter so you can turn the light off with the filter running. My new betta and I are very pleased with this tank.”

It’s also essential to get a tank that won’t leak. The Aqueon Aquarium Starter Kit is a great option and one fish parent has this to say on their Amazon review:

“Lovely tank. The filter is great, the heater keeps my bettas happy at 78C. Of course, with any new tank (ordered online or bought in-store) a risk for leaks is present. Aqueon is a good brand but things happen. Fill your tank halfway, check for leaks. Fill it up and check each day for two days. In this hobby, there is always a risk. I upgraded the lid to the Aqueon Glass lid and it fits perfectly! You can’t go wrong. My betta girls love this tank.”

Overall, we hope these products help you find a spacious home for your betta to enjoy. Take a look at our FAQ section to make sure we answer any possible questions you may have!

The Best Betta Fish Tanks for 2022 FAQs (Frequently Asked Questions) 

Is it true that betta fish become lonely? 

Betta fish are territorial by nature and should not be kept with other betta fish since they would fight and hurt each other, frequently leading to death. They are unlikely to become lonely in their tank, although they may become bored if it is too tiny.

Is a betta in a 20-gallon tank too large? 

If you want to obtain some tank buddies for your betta, a 20-gallon water tank is a perfect size. At this capacity, you’ll be able to keep fish like tetras, who require more space to swim, as well as fish like mollies, which may grow a little bigger than bettas.

Do betta fish require filtration? 

Betta fish are usually kept in bowls. That implies you won’t have a filter or a heater. Even those who have betta fish in small tanks rarely give filtration or hot water, and they make it through most of the time. This easy way to take care of a fish is what keeps the betta so appealing.

Do Betta Fish like to be in the light? 

Yes, anything too bright can irritate them, but a basic aquarium light would suffice. Bettas also enjoy aquatic plants, which require aquarium lighting to thrive.
