I have a divided 10 gallon tank with a male betta on one side and a female betta on the other side. I also have a 55 gallon community tank where I have 7 females. It's been difficult to keep the sorority fairly balanced in the big tank because I was advised that there needs to be more females in that sized tank to spread out the aggression.
And recently I look at the tank and think I'd like more schooling types of fish rather than 10 more bettas. So I had this idea where I can move the divider in my 10 gallon so that one side is larger, and keep my 7 females there? So I'll give my male betta about 2-2.5 gallons and the other side will be about 7.5-8 gallons for my 7 females (possibly 6 because I might have to keep one by herself). I'll get a lot more plants, of course, but is that too cramped of an area for 6 or 7 female bettas? Will they fight more in that small space after being used to the big space?
Then in my community tank I can get a giant school of purple passion danios (they look so cool in a big school) and keep them with my zebra danios, neon tetras, and julii cories that I already have.
Will that work?
