I've heard many people on this site say that a minimum of 10gal is needed to keep a sorority, i was wondering if it would work in a tank with the dimensions of 60cm long, 30cm deep and 40cm tall (or 23.62 x 12.2 x 16.14 inches) roughly. Since it's double the minimum volume it sounds like it would be good. In my opinion it would be a fairly tall tank, but not very long. Would this be large enough for roughly 6 female bettas to live together in harmony? I don't know if a shorter tank is better since they would be more spred out or if it doesn't matter as long as the overall area is large enough?
I've always wanted to set up a sorority, but thought my tank wasn't suitable. Just curious if it would be possible?
