Is this crab good or bad?

[jse08]

Today I moved my peppermint shrimp and some live rock from my 10g to a 5g hex and I just saw this crab in the tank. I never saw it in the tank before but I'd like to know if its a good or bad crab.
Thanks in advance!

I wouldn't trust that crab in my tank unless it was a Mantis tank.

haha, what kind of crab is it?

It's nearly impossible to ID most crabs with only a picture.

well its around 1/2" across, two claws about the same size, it appears to have hair all over the shell and legs.

There could be 100 species of crab that perfectly match that description.
