This variety of Betta has a striking, elaborate tail that differentiates it from other Bettas. The Twin Tail has a split tail, almost giving the suggestion of having two tails. A similar fish, the Crown Tail, has a teardrop shape to its tail. The Twin Tail Betta is a type of "Siamese" Fighting Fish. These fish have been bred over the years to enhance the fins and remarkable variety of colors of the males, as well as making them increasingly combative. Therefore, only one male should be kept in a tank; however, smaller, shorter-finned females may be housed together. Females can be as colorful as the males, although, they rarely have the long finnage that is seen with the males.

Twin Tail Bettas are considered labyrinth fish, meaning that although they are equipped with gills, they also have a special organ which allows them to also breathe directly from the air. As a result, they must have access to the surface of the water in the aquarium. The Twin Tail Betta requires a warm, stable temperature, low light level, and a densely planted 10 gallon or larger aquarium.

Once laid by the female, the eggs are tended by the male in a bubble nest. Fry appear in about 24 hours and must be fed very small food initially, such as crushed or powdered flakes and newly hatched brine shrimp. Fry will also take finely chopped hard-boiled egg yolk.

A carnivore, the Twin Tail Betta will eat all types of live food as well as freeze-dried flakes and frozen foods.

Ideal tank mates include: Tetras, Rasboras, Danios, Angelfish, Guppies, Platies, Mollies, Swordtails, Loaches, Plecos and Catfish.
