My wife and I both have 3 betta's now. A Plakat female named Darya that we added to our community tank (she seemed to be really stressed out and depressed on her own, but as soon as we added her to the Community tank she was *boom* happy - and there have been no problems), a VT male named Constantine he lives in an 8 gallon aquarium with two otos, and our new CT guy Xerxes who lives in a five gallon all by himself.
