Have you looked at the deep-water angels in the Genicanthus sp.? They are more reef safe and less aggressive than some of the others. Maybe not as eye-catching as say a Regal or Majestic but some of them are quite nice. I particularly like the Bellus Angels. I have a Lamarck's in my reef and it has never touched a coral.
