Betta sorority in a 15 gallon?

[Angelfish owner]

I have been thinking about getting a 15 gallon in the future and was wondering if I could put 5-6 female Bettas in it. Would this be possible?

I wouldn't do less than 5g per betta. So 3 would be a better number. Add them all at the same time to help reduce aggression

Add an odd number to minimise the chances of them ganging up on the weakest one. So either 3 or 5. And plenty of hides/plants etc. The bigger the tank the better, and keep in mind that sororities are always a hit and miss... they can go bad after a while, so it's always a good idea to have a backup plan just in case.

I'm looking at a 15-20 gallon for them. I know that I have to make it have lots of hiding places so everyone has their own territory. This is just research for the future
