I've heard different things so I'm a little confused. I've always heard that you can keep female bettas together as long as you have around 6 of them. But recently I've been told that it's not a good idea to house female bettas together unless they are sisters. I was hoping that someone could share their experience with housing female bettas together. I'd really like to have a tank of bettas, but I don't know if it's a good idea or not....
