Definately, you don't want to ever have just two females as in general one will be stronger and chase or pick the other to death.
(its open so they can swim in), i came home late 1 night and turned on 1 of my lights and my 2 female bettas and 1 of my gouramis were in there snoozing but of course when i turned on the light all my fish swarmed to the front because they thought it was dinner time (the mods need to add a pig icon) Hi caroline, my tank is a ten and it has 5 females. I wouldn't go less than 3 to spread out the aggression. Four is supposed to be a magic number, but I had a weaker one in there and three strongs, so I added a second weak and now it's fine.![]()
If you do this I would make sure you have back-up bowls because there seems to be a lot of trial and error.![]()
