Sorry kinda hard to get a picture but the weird thing is I have no crabs. Just snails

Maybe the link below will help with an identification. Lot's of various crabs will hitchhike there way into our tank via the live rock we use.

If your going to put it in your sump, just make sure it can't get trapped in your return pump or your skimmer. You don't want it to clog the pump or damage the impeller in any way.
