Flame Angel Reef Safe?

[Reefie]

I've always wanted one of these bad boys. I love the colour and livelyhood of them. The problem is if they are reef safe? I have an SPS dominated tank with a few LPS and 5 Crocea Clams.

I've been told that they are 50/50 chance of nipping at my corals. I've also read of quite a few accounts online that they haven't nipped at corals in quite a few tanks.

I'm asking for your opinions and experiences, so I can make my decision whether or not to risk getting one.
