HELP!
I've just added a stunning coflake beauty to the tank, and it's being bullied by one of the yellow tailed damsels. The rest of the gang - 4 chromis, hawk nose, maroon clown, yellow tang, and Banggai cardinal - seem fine, but this damsel's gone rogue. It's been chasing the beauty around the live rock for hours, I see glimpses of the chaos, and it's not pretty - the damsel's got a scratch above its head, and the beauty's lost chunks of fin. I'm at my wit's end, can't catch either without tearing the whole setup apart. Anyone got a solution, or am I in for a nasty surprise - dead fish, or worse, infection?
