    Could be a emerald crab, normally not to much of a problem and quite reef safe .

    He will eat the caulerpa in your tank. If you look at the stuff on the right you can actually see the little pincer marks were he's had some.

    It looks like a emerald crabs to me as well, they are a member of the cleanup crew m8 they scavenge the aquarium for leftover food or algae and help to keep the aquarium clean. One of their claims to fame is that they will eat bubble algae (valonia) which is a nuisance hitchhiker on live rock from time to time. here is a picture of one of mine
