Maybe the dwarf angel. All angels are considered reef safe with caution and most members will tell you its 50/50 and tell u stories of an angel being fine for years then going rogue over night.
Personally a lot has to do,with the specific angel, coral beauty and flame angels are a much safer bet than a lemonpeel or eibili. Also keeping them well fed and have a lot of corals so no one gets too much attention. Most angels eat mucous off the coral and not the actual polyp, if you have 1 coral and it picks on it constantly the coral will be too stressed. If you have 100 corals to spread the love things work out much better.
I kept a flame with sps, softies, lps, and mushrooms. Only coral I couldn't keep with him was a fungia plate and acans but everything else was good. I wouldn't keep an angel in anything but a reef, that is their natural habitat and there is a lot of food sources and diversity in a reef to help them fare better. COPPS totm write up has always been an inspiration to me and I can only hope to be 10% as successful as he has with hard to keep species in reef tanks.
