im debating about turning my 10 gallon into a betta sorority. if i go that route how many should i put in there?
Some say lots some say single. It just depends on the bettas, just like when you house males with other fish IMO. Years ago I had 2 females with a few guppies in a 2 gallon tank. Now that I know more about fish I would NEVER recommend that. I am just mentioning it to say that no one picked on anyone in that tank.
I would say that if you decide to get around 5ish, get them all at the same time and be prepared to make changes to the set up if need be.
