There are not. Most angelfish like to nip at corals. Some people with larger tanks put them in, but they usually have lots of large, established colonies throughout the whole tank. So the biting is spread evenly through all of the corals. If you put them in a new tank with some small frags and a colony or two, there is a good change your corals are going to be toast.
And I would not call a coral beauty reef safe.
