Scientific name: Betta splendens

The Siamese Fighting Fish has been bred for its incredible variety of colors and long, flowing finnage. They are a colorful and attractive addition to any tank, but problems can arise in keeping them. Males are highly aggressive with each other and can't be kept in the same tank. Siamese Fighting Fish are also quite aggressive toward females most of the time. Although a single male can be kept in a small community aquarium, it will likely be harassed by any fin-nippers.

A water temperature of 76º to 86º Fahrenheit, a pH between 6.0 and 8.0, and soft to moderately hard water are needed. Flake and freeze-dried foods high in protein are taken, as well as very small, floating pellet foods and live brine shrimp on occasion.
