The NoClean Aquariums GravityFlow Betta tank has an interesting design that makes it easy and fun to clean your Betta’s tank. But overall the tank is much too small for a Betta fish, and the small size could mean more maintenance in the long run, despite the “no clean” design.
While this is great as a novelty item or conversation starter, if your goal is a happy and healthy Betta fish you should look for a tank that is at least 2.5 gallons in size.
Every day people buy Betta fish, keep them in small fishbowls or vases as decoration, do not care for them properly, and are left with unhappy, unhealthy, or even dead fish. If the GravityFlow tank encourages cleaning and performing water changes, then it’s certainly better than a fishbowl.
