Possibly a gorilla crab or no ? He's not Harry and has small pinchers though like a algea eating crab idk

It might be a bandit acro crab, which are good.

I would have to see it's face, if he looks like hes wearing a dark ninja turtle mask hes probably a good guy, takes care of certain SPS.

Here is a picture, not my picture, mine got eaten by my flame hawkfish. (Photo lifted from "The Reef Tank") http://www.thereeftank.com/forums/f6/found-this-crab-on-my-sps-is-it-good-for-the-sps-209986.html
