Brent, I have a Flame Angel that seems to take a nip every once in a while, but doesn't seem to do any real harm. After quarantine I put several frags of different corals in the quarantine tank with him and he seemed to leave everything alone. I can't tell if it is nipping at the corals or pods, but at one year in if he is doing any harm it isn't noticeable. There will always be a chance it will go rouge, but they are such beautiful fish I took the chance.
