Let me start by stating that I do not have a Rock beauty in my reef tank. I have had several in the past, in fowlr and reefs. This angel is not as difficult to keep as some claim, though it is not easy. It may eat, as an adult, mostly sponge in the wild, but they do just fine on less exotic fare in captivity, as long as they get a high quality varied diet, and they are started before they get too old to accept radical diet changes. I've had good experiences with these fish when they were captured (by me) at slightly more than an inch, but less than two inches. Others may disagree, but this has been my experience with fish that I personally hand caught and transported with great care.
I don't think these angels make a good reef fish. Neither do their cousins, the Queen Angels. A strong healthy Angel of this genus generally will tear things uo, and eat all sorts of creatures you probably value: tube worms, tunicates, small shrimp, hermit crabs, small sessile invertebrates, clams, and almost anything else they can swallow. The bigger they get, the more damage they are capable of. They can strip live rock with astonishing speed and zeal.
These are great fish, but it's a mistake, I think, putting them in a delicate reef tank.
