Crab ID help.

[Chuu]

I've had my nano setup for 14 months, it's in my bedroom with my PC which I spend alot of time at so i'm always at the tank and for the very first time last night after lights out, this wee 1 inch crab is just walking along the front of the glass!!

I've had no additions that would carry a crab and certainly nothing in the last 6 months at all, so this guy must have come in on the rock as a baby..

Here is some pics if anyone can ID:

I am just shocked I only just saw him for the first time last night.

A couple of things make him a bad guy. Usually hairy legs, black claws, and uneven claws make him a reef enemy. It's most likely a Mythrax sp. Probably what we reefers commonly refer to as a "Gorilla Crab." Get him out of there!

Thanks, he is out now anyway, used an old jam jar with some mysis in it.
