reef lobster maybe predatory?

[BioMan]

over the last month my Long Tentacle anemone, 6 line wrasse and a clown have disappeared. They didn't jump out and I can't find them anywhere! I have a reef lobster for a few months now and he seems to stay where he is (but I know he sneaks out at night) but I can't think of anything else that would kill and dispose of these things. I can understand the fish getting caught and killed but not buried, and the anemone disappearance has me baffled. my tank that these guys live in has been running for 10 months. all water params are ideal. anything like this ever happen to you all? could these guys be scared and in hiding until I move the rock work?

The fish could have become food, but I highly doubt the anemone would have been eaten by a purple reef lobster. Are you sure the anemone isn't in the rock work somewhere or perhaps behind the rock work?
