Can anyone ID this crab

[keith10]

So I was feeding a couple times and thought I saw a large pincher came from under a rock. I didn't think much of it. Then the other day I saw its whole body. It is a rather large crab. It looks black and it's legs are black with white strips. I included a image. It's sideways but maybe someone can see enough of it to tell me it's ok. I didn't buy it, it must have been a hitchhiker and just grew and grew. Thanks in advance for any comments

Your picture is pretty rough.

Was it hairy with black tipped claws?

I would sump it until someone id's it, looks like a gorilla crab.

That claw looks pretty hefty for its size. Picture is not good bough for I'd. Corals, snails, and inverts are probably on the menu when it is hungry
