Could be a million things. Unfortunately, without a picture, it's almost impossible to identify. Can you see the eyes? Color? Is it a dark green?
I had a dark green Xanthid crab, caused absolute chaos in my tank.
You should quarantine this rock until you can identify this crab or you could have major problems on your hands.
