Betta FAQ

Native Region:    Thailand.
Temperament:    Community, but may be damaged by fin nippers such as Barbs.. Usually very peaceful with other fish, but not two male bettas.   You can only put one male Betta in any tank.  Males do not like other males and this is why they are called "FIGHTING FISH".  Females can be kept together, but should only be put into an aquarium with a male when she is heavy with eggs.  In short, keep only one male betta in a tank as a bachelor!  Can be kept with non-aggressive fish like tetras and guppies, but to protect you betta, avoid Barbs and Cichlids, even "angelfish" as they begin to get some size.

General Comments: Very beautiful and popular fish that is easy care.  Many strains are available.  Easy to take care of, because it comes from rice paddies in S.E. Asia, thus is very tolerant to a wide range of water conditions.  However, changing about 10% of their water (aquarium and 25% -50% weekly for bowls), will keep your betta healthy, colorful, and active.
