Something Is Moving and Eating My Zoanthids!

[NYReef]

There is something in my tank which I have never seen that takes any zoanthid covered branch (3"-4") and pulls it into a cave in the rock and eats the polyps off! It must be very strong to carry the whole branch off, yet I have never seen a critter to match the description. I have blasto's, ricordia's, brains, acans and clams which are not touched, thank god. Thoughts or idea's? It must be a crab of some type to be so strong, but I never see it lights on or off. And, if anyone what it is, can you tell me if it can be removed?

Try a coke bottle crab trap and see if you catch anything.

It may also be a Eunicid worm.. check this out

I agree that it is probably a crab though....
