While DIY betta tanks with multiple chambers are preferred by a few veteran aquarists, self-cleaning tanks are considerably more popular among beginner and experienced fish-keepers.
In this article, we’ll go through the 10 best betta fish tanks that you can choose from.

A small yet convenient package, the Tetra Bubbling 1-gallon aquarium is almost perfect for your betta. Made with Acrylic, this lightweight fish tank’s design and filtration system effectively minimize the maintenance requirements. However, your betta will be much happier with at least a larger 3-gallon tank.

Cycle your fish tank through an array of differently colored LED lights. The LEDs are synchronized with the bubble disk and change their color after specific intervals.

Despite its small size and lack of space, an efficient bio-filtration system is present in this package. However, it may also reduce the 1-gallon space further.

Summary: Best overall betta fish tank.
Considering there are hundreds of other betta fish tanks, we’ve prepared a buying guide for you to choose the best one among them.
The absolute minimum space requirement for betta fish is 2.5 gallons to freely swim, hide, and explore decorations. The recommended tank size, however, is 5 gallons.
In contrast, there isn’t any upper limit when it comes to tank size. Larger aquariums maintain better water parameters and provide ample swimming space.
Most betta tanks that are below 3 gallons, are considered display tanks and aren’t suitable for healthy inhibition. Anything less than that would require frequent maintenance and water change.
Being one of the most abused fish species, they often are forced to inhibit small spaces without adequate filtration. Although bettas aren’t as high bioload species as Goldfish and Cichlids, they also produce a significant amount of ammonia and nitrite in the tank.
Ensure that your betta fish tank comes with at least biological filtration and enough water flow to keep the betta moving at a slow pace.
The best betta keepers pair them with plants to offer places to hide and explore. Therefore, ample lighting to grow plants is critical for a balanced betta fish tank.
Moreover, even if you choose to go with artificial plants, adequate lighting can enhance the colors of your friendly betta to a great extent.
While acrylic, as a material, is similarly inert to toxic chemical reactions as glass, it’s much more scratch and stain-prone than the latter.
Additionally, check for leaks, flimsy lids, quality of the hoses, foul smell, and any residues in the tank before choosing your betta fish tank.
Replacement filter cartridges, broken equipment, and shipment damages would require you to contact customer support for the Betta fish tank. Check online reviews and availability of both email and toll-free numbers to ensure the same.
Furthermore, as these self-cleaning tanks are more lenient towards offering convenience, make sure that the replacement parts are easily purchasable and are available online.

Self-cleaning fish tanks are best for betta. Choose a tank that is at least 5 gallons in volume and has adequate lighting and a filtration system in place.
As bettas naturally inhibit shallow waters, vertical tanks put undue pressure on their body. You may consider vertical tanks for your betta fish, only if the horizontal space isn’t extremely narrow, and has enough swimming space.
Yes, you do need a filtration system for your betta fish tank. However, make sure that it’s only enough to maintain a laminar flow and doesn’t stress your betta or the plants.
The Bottom Line
We’ve listed the top 10 betta fish tanks that you can buy online. We also have included a buying guide if you choose to deviate from the list. Hopefully, you’ll now be able to install and maintain a healthy betta fish tank that supports both your betta fish and live plants.
