I would not do an angle either. its not even the fact that they can nip corals, because if you get them small they usally leave the stuff alone. I have a reef with a coral beauty and it doeant bother a thing.. the point about it is that they get up to 5 inches and if you put it in their they are very active swimmers and will not be happy. its just my personal advice you can do what you want I already stated before I wouldn't even think of doing a fox face nor a angel.
