I keep 1 male betta and 2 females in my community tank. There are also guppies, tetras, swords, hatchet fish, cats, ETC. Almost any NON - AGGRESSIVE fish can be kept with them as long as they arn't nippy! (Tiger Barbs are nippy!) Watch the females as they can be touchy when more then one are kept in the same tank. If they get aggressive with each other, seperate them. I have found that the females don't do too bad when they were raised with other females, but if they are used to being seperated, THEY WILL FIGHT!! I have three females that have to be kept seperated or they will try to kill each other!! The rest of them think they are one big happy family!!!
