My coral beauty doesn't really bother my corals. He irritates them when he plucks algae from near them but that's it. Is still ditch it in a minute for a different fish.
There are quite a few fish to choose from, but like you said, the chance one or more may munch on corals is pretty good for most. I do like coral beauty, flame, and potters angels. I also like those green clown gobies. They don't take up much room and are pretty cool looking close up. Catalina gobies are nice too. Any of the fairy wrasses are also good choices.
