Great thread! It's nice to see so many people with good or relatively good experiences with Angels in a reef aquarium. I will add my experience. I have owned two flame angels and a Potter. None of these dwarfs touched anything (LPS, SPS, softies or anemones). I currently own a Juvenile Regal and for the most part I'd say he is reef safe. The only think he went after was a Brain coral. He hasn't bothered my Zoas, or other corals. He leaves the anemone alone as well. I cannot comment on clams, as I own none.
