My girlfriend wants to set up a standard 10g tank as a betta sorority. I'm thinking heavily planted, natural rock caves, and plenty of driftwood. She was going to put 6 or so variously colored female bettas in there. I know several of you out there have done this successfully, so do you have any tips? Should we attempt to have distinct hiding places for each fish, or will this encourage territoriality? Also, do female bettas get as bugged by current as males? I ask because she wants to put an overpowered HOB on the tank for good measure, and we figure it'll probably be ok since the fins are much smaller.
