I have this coral beauty in a 300 gallon tank with a flame angel. They have not had any problems for years, but for some reason my flame angel decided he wanted him dead. I though he was a goner, but after a week in a seperate container it looks like it will be fine. However I am not going to put it back in with the flame angel, so if anyone wants a beat up coral beauty, it is free if you can pick it up.
here is a picture, sorry it is not very easy to see, but you can see how he is beat up:
