Don't add any centropyge angel to your tank unless you understand you may have to catch it to save your corals.
I added two flame angels to a reef tank. One of them started munching on SPS immediatly, and funny, it was only certain Acroporas and my M. digitata, but not others. The other one eventually started that too, I believe she learned by watching the other but who knows? Anyway, I had to catch them both, and they both behave nicely now in a softy tank.
I had a C. argi that was good with all kinds of corals, and even my clam. But I occasionally read reports of one not so well behaved. It is my opinion though that they are typically pretty well behaved (in the coral eating department at least!)
