I have had both with no problems. The coral beauty was a great fish, He never bothered anything in my tank. Unfortunately I lost both to a moving anemone, but I wouldn't hesitate having the cohabitate.
I may be wrong and certainly don't want to put words in someones mouth, but I am pretty sure that DOC MARCO (where has he been anyway?) said that he has never had any problems with the coral beauty either.
Good Luck
