Ive had mine for 2 weeks, and at 2 inches it is eating everything!! It nips my clam, lps, sps, and most anything it can. No damage yet, but it is making me mad!! Beautiful fish though, and gets large for a dwarf angel. I mite just have to pull the corals for now and see if some heavy feedings will wien it from eating corals. But I guess it is like all angels, you never know, because I have a pair of flame angels in there to and they havent tuched a thing...
