Is this a gorilla crab?

[Photobug]

We have not added anything to the tank in a month or more. Nor have we added any rocks in about 10 months. We have no idea where this crab came from. It just popped out a rock and started eating from off the rock.



Sorry for the pic quality, but is it a gorilla?

Can't tell from just the legs alone. You'll want to trap it to get some decent shots of it. Bait a tall, smooth sided glass with a bit of raw seafood and tilt it against the rockwork at night. Crab climbs in for food but can't climb back out.
