Monitor them for the first 30 mins or so. Seperate them at the FIRST sign of aggression.
Thanks, I will keep this in mind.
I think I will stay away from the ones with the fancy tails, but I do want to try some colorful ones. What is your opinion as to setting up a tank first with the fish and adding the betta last versus having a betta first and then adding the other fish? I am not really set on one way or the other. I am leaning on setting up the community tank first, then adding the betta; however, if I come across a beauty of a betta first, I am not going to pass it up!!! I wouldn't mind having a lone betta for a while either though, since I haven't had a tank in so long. I can't wait!
