What's eating my soft corals....?

[janet]

HI all
A few weeks ago I got a Eunice worm out of my tank. Very glad to get that out. But, something is still eating my daisy polyps and my pulsing xenia... Any ideas what this could be and how I can catch it?
I have in my tank: Pistol shrimp and watchman goby, clown fish with bubbletip anemone, Bangaii cardinalfish, Mandarin fish, 1 blue legged hermit crab and 2 red leg hermits, 2 cleaner shrimps and a black mithrax crab. I really don't think it's any of those eating my soft corals. Please let me have your thoughts and suggestions.
Janet

You need to go hunting at night with a red light and a magnifying glass.

my guess would be the crab but its hard to say w/o catching one in the act

Are you sure it is not a water quality issue? Poor water quality will cause corals to waste away.

I also recall suggesting in a prior thread that you may not have enough light to keep corals. I think this is still the case.
