I'd like to start a betta sorority in a 20 gallon tank. How many bettas should I put in without causing aggression? I've heard of people putting in 8 and they fight, so is 3 or 4 a good number? I'll make sure to include lots of hiding places and watch carefully for any early signs of dominance or chasing, I have a backup plan if I need to relocate a fish into a different tank as well.
