The 25 Top-Rated Betta Tanks for Thriving, Happy Bettas

Betta fish are also known as Siamese fighting fish, and for good reason: they fight. For this reason, bettas must be kept separate from other bettas and, typically, other varieties of fish, as well. They do best in small tanks with regular water changes, although because they are labyrinth fish – meaning they can take in oxygen through their gills as well as breathe oxygen from the air – they can survive in stagnant, non-oxygenated tanks.

These traits make the colorful, lively betta fish an ideal choice for livening up your desk at the office, for kids or those who are just getting started with fish keeping. While bettas can survive and even thrive in an ordinary fish bowl, giving your new pet the best will ensure that he stays happy and healthy to brighten your space for a long time to come. We’ve rounded up 25 of the best, most innovative, top-rated betta tanks to help you choose the best environment for your betta. The average ratings listed below are based on feedback from Amazon.com reviewers and are current at the time of this writing.
