Don't waste ur time or money, angels are away to curious of a fish to trust in a SPS dominated tank, and they're not cheap, nor is losing a coral, and U WILL loose corals. The angel might eat it, or try to eat it and knock stuff down, etc.... If you are looking to ad some more color to your reef, check out different anthias, and there are a few wrasses that are 100% Reef safe and won't even eat snails/inverts. The Flame Wrasse is a prime example of one. Anthias like to school too and are relatively cheaper in comparison to Angels.
