Just how nasty is the Red Terror(festae). I've been reading about them and they sound pretty cool. I'm a long way from getting a pair (a breeding pair) but am seriously considering them to be the next fish I get. I have a 120 gal. and from what I've been reading they reach a max size of about 7"-10". I don't mind keeping them by themselves if tank mates would be out of the question but would like to have some sort of schooling fish with them. I would appreciate any input or comments that you could give me.
