Good crab or bad crab????

[dleko]

We found a few of these crabs on our tbs rocks. We started out tank 2 weeks ago, and have just finished our cycle. We will be getting our next shipment of rock this weekend and want to make sure we have all the "bad" hitchhikers out before that. The crab is upside down next to the orange sponge. Please help I.D.!!

I can't make out any detail on the crab, sorry can't help with the ID.

Sort of looks like a ruby cling crab, but hard to tell. If it is they are are OK, but keep an eye on it to be safe.
