yeah saying they're not reef-safe is a bit much. they are reef-safe, but I know they munch on aptasias, and suspect them of eating xenia. deep sixx you may be right, what I have in my tank could be camelbacks, they sure look like peps with no hump on their back, but i'm no expert either. all I know is they are aggressive eaters and scavengers and need to be fed heavily to prevent them from eating things you do not wnt them to. IMHO my tank will be none the worse off with them absent, probably better for my desires which is more of a full softie underwater garden than rocky coral reef.
