Divided into three equal sections, this Triple Betta Tank holds three Betta fishes at a time! It’s an acrylic enclosure that has a built-in LED light. This tank floats on the top of your aquarium, thus, you can use it as a hatchery or an isolation tank for Betta fishes. The tank dividers are also removable, thus, you can adjust the size of each section by moving the dividers.
