The best performers in our review are the EcoQube, Tetra Cube, and Aqueon Kit Betta Falls. Here’s more information on choosing the right Betta fish tank for you, along with a detailed review for each product we chose.

About the Betta Fish

You’ll usually see Betta fish hanging out alone, and in relatively small tanks. The species is known for it’s territorial nature, and two males should never be kept in the same tank; they will fight, often to the death. Aquarists that like the idea of having multiple Bettas often buy several aquariums, and house them separately. Almost all Bettas that you’ll see in fish bowls and pet stores are males; females are less colorful, have visibly smaller fins, and are kept in “sororities” of at least five fish. While females are somewhat less aggressive then males, it’s not a good idea to keep a male and a female together, except during breeding.

Betta Fish Tank Size

Most pet stores keep their Betta fish in small jars, without any heating or filtration, and will likely tell you that it’s fine to do the same. This is a very common misconception, and is not true! While you don’t need much to keep a Betta alive, there’s a difference between keeping a fish alive, and having a happy, healthy fish. The misconception that Bettas like living in coffee cups is false; your Betta fish tank should have a capacity of at least 2.5 – 5 gallons. This will allow some room for the Betta to swim, and will allow space for a heater or a filter if your Betta happens to need one. Which brings up the question:

Does my Betta fish tank need a filter and a heater?

Betta fish thrive in temperatures between 74 and 80 degrees. If the temperature in your aquarium is lower than 74 degrees, a heater is advised. Bettas are a tropical species, and will not react well to colder temperatures. Unfortunately, many Betta fish bowls on the market simply don’t allow enough space for a heater; let alone include one. We’ve put emphasis on aquariums that have enough space – both for your Betta, and for additional equipment.

An aquarium filter is always advised, regardless of the type of fish you’re keeping. However, Bettas come from stagnant waters, and can get stressed from strong currents of some filters. To top it off, their long fins may get caught in the filter, especially if the aquarium is too small. If a Betta fish tank comes with an included filter, the flow should always be gentle.

Fluval Betta Fish Tank

1. Fluval Edge Aquarium

Check Price & Availability on Amazon >>

We liked: Filtration and lighting included. Large capacity.
We didn’t like: Small water surface area.

Our #1 best Betta fish tank. Many manufacturers forget that an aquarium’s main purpose is to be visually pleasing. If you’re planning to buy a Betta, your usual choices usually boil down to either a fish bowl, or a tiny cube. With this in mind, the Fluval Edge was a refreshment. The design is absolutely stunning; the aquarium itself is propped up on a pedestal, with all six sides visible for your viewing pleasure. The lightning, filtration, and wiring are conveniently out of sight, tucked away in the center column. This unique design gives off an illusion of a floating, seamless cube of water.

The Fluval Edge comes in two sizes; a 6-gallon, or a 12-gallon, which is more than comfortable for a Betta fish, and can accommodate a heater, decor, and plenty of plants if needed. If your Betta is friendly, you can use this additional space to add a couple of peaceful community fish as well.

Unfortunately, Fluval Edge’s beautiful design comes with a flaw. The water surface is hidden under the small lid on the top, where the filter outtake is located. Betta fish, which are able to breathe air, need access to the surface at all times – and they usually don’t like going near the water flow. While most owners we’ve reviewed claimed to have no issues with the design, some Bettas may be confused by it.

Back To The Roots Betta Fish Tank2. Back to the Roots Water Garden

We liked: Fun and unique. Low maintenance.
We didn’t like: Plants may require sunlight – but sunlight can cause algae.

And now, something completely different. The market has seen a boom in “aquaponics” fish bowls in the past years. Many of these products make very bold claims – the main one being that no water changes are required, ever. How is this possible?

The top of the tank has six pods that can house several plants. The idea is that toxic waste produced by the Betta fish is absorbed by the plants. This helps them grow, and acts as a natural filtration system in return. The result is a self-cleaning aquarium that requires visibly less maintenance than a typical Betta fish tank.

While great in theory, this system has some faults. Without regular water changes or cleaning, the water can get dirty, and full of algae. If you decide to buy this tank, we suggest getting a snail, or a couple of ghost shrimp, as they will help keep the water clean. Thankfully, there’s plenty of room for that – at a capacity of 3 gallons, this aquarium should be able to house one peaceful Betta and a neighbor or two.

Tetra Betta Fish Tank

3. Tetra Cube Aquarium Kit

Check Price & Availability on Amazon >>

We liked: Good price-to-quality ratio.
We didn’t like: Not as good as some other options.

If you’re looking for something simple and affordable, the Tetra Cube Aquarium Kit is a great choice. It doesn’t offer any crazy features, but it does everything a Betta fish tank needs to do – and more.

The Tetra Cube Aquarium has a total capacity of 3 gallons, allowing more than enough space for your Betta to swim around. The measurements are 10″ x 10″ x 10.5″, making this tank compact enough to fit on your desktop. Still, there’s enough room to include a small heater and a few plants for your fish to enjoy. The tank also includes a modest (but sufficient) filter, ensuring a healthy environment for your Betta. The LED light included with the tank won’t be enough to grow demanding plants – but it does the job, and gives a nice view of the tank. While the construction is plastic, it’s shatter-proof, and just as transparent as glass. The seamless edges give this Betta tank a very sleek look.

Overall, we found that the Tetra Cube is sturdy, affordable, and a go-to if you’re looking for an entry-level tank for your Betta. Still, despite it’s simplicity, it offers more than many similarly priced Betta aquariums.

Fluval Chi Betta Fish Tank
4. Fluval Chi II Aquarium Set

Check Price & Availability on Amazon >>

We liked: Relaxing and beautifully designed.
We didn’t like: The extra decoration light can’t be turned off.

If you’re a fan of the saying that “less is more”, you’re going to love Fluval Chi’s clean look. Despite it’s minimalist design, the Fluval Chi II comes with everything you need to get started. A small filter and LED lighting are included with the aquarium.

Both the filter and the lighting are concealed inside the seemingly “floating” box on the top. The filter pulls water from the aquarium, and releases it back through a small stream – resulting in a calming sound of flowing water. The filter provides a very gentle flow – perfect for a Betta fish, although if you plan to use this tank for anything more, we’d advise buying a stronger filter.

The top box is decorated with an additional blue light, which is permanent, and can’t be shut off without unplugging the filter. If we had to pick one flaw about this fish tank – this would be it. If you plan to keep it near your bed, the top light is sure to annoy you at night.

On the upside, the Fluval Chi II has an impressive capacity of 5 gallons, and that’s great. Most Betta fish tanks we’ve come across are considerably smaller. The measurements are 10″ x 10″ x 14″, allowing you to place this tank almost anywhere.

EcoQube Betta Fish Tank5. EcoQube Aquarium

Check Price & Availability on Amazon >>

We liked: Fun and unique. Low maintenance.
We didn’t like: Slightly smaller than ideal.

Similarly to the Back to the Roots garden, this Betta aquarium boasts with it’s low-maintenance system. It’s filter relies on a live basil plant, which consumes the toxic wastes in the water, acting as a natural source of filtration. No water changes are required. The cool concept is topped off with a cool design – the EcoQube Betta tank is beautifully hand-crafted from flame-polished acrylic, and comes with included LED lights for better viewing pleasure.

We should note that the live basil plant does not come with the product, and you need to plant the seeds yourself. The plant can take up to two weeks to grow; During this time, the water could be unsafe for your Betta. Although this may seem tedious, remember that patience is everything in fish keeping, even if you only own a small Betta tank.

The biggest problem we had with the EcoQube was it’s size. At a capacity of 2 gallons, it’s visibly smaller that any other Betta fish tank in this review. Bettas like having some space to swim. Without water changes, algae may become a problem, and this tank just feels too crowded to introduce shrimps, plecos or other algae eaters.
