I am considering putting Trey in the 5 gallon with my two remaining guppy females. She would be very closely supervised at first, but before I try the experiment I was wondering if anyone else has kept female bettas with guppies. I would never try it with a male; but I know that females are sometimes kept successfully in community tanks with certain types of fish. Trey is still fairly young, which I understand optimizes the potential for acclimating to tankmates. What does everyone think?
