Thanks all.
110galreef - yes, a bluejaw, regal angel, and a baby imperatur angel

The bluejaw is no problem to my corals, but the angels nip occasionally. LPS are hit and miss - can't have acan lords, but
SPS are fine (no daytime polyp extension as it is in the wild, but are growing and seem healthy). My more toxic LPS (favia, frogspawn, chalices, etc.) also tolerate the occasional nip without a problem. I feed very heavily (5-6x day) which probably helps. No clams so can't comment on those, but my shrimp and starfish are all left alone.
