unidentified critter help!

[seacritter]

I received my first shipment from TBS a few weeks ago and will be getting my second shipment tomorrow. Last night while shining
a flash light in the tank with the lights out I saw something very big coming out of one of the rocks I can't identify. It is about half inch in diameter, seems to be about 4 inches long and brownish gray in color. It's a very scary looking creature and I am concerned
about what it is and what it could do to my future livestock. Does anyone have any idea what this could be?

A gorilla crab maybe? I know the first time I saw a big one my thoughts were "Hand me the harpoon, there's a monster in there!"

A picture would definitely help. :)
