I've had one in my SPS dominant tank for 6 years with no issues. I haven't really had any aggression issues either. My recommendation = try to find a small one.I can't remember if I asked this in here, but my wife REALLY wants a flame angel for our mixed reef 125. I'd love to get her one, but we're worried about aggression and corals. I know each fish is different, and honestly, none of our fish so far have been anything like what their normal description seems to be, so it's pretty much a gamble every time so far.
Are flames really that aggressive though? We had a female bellus angel that went completely rogue, attacking quite a few fish. Tank wasn't stocked much then either.
My previous main concern was our coppperband, but we've since given up on them and don't have any fish nearly that sensitive anymore. Any advice?
