    Another ID please

    Two nights ago, I was looking for my bristleworms with a red light in pitch black. Couldn't see'em.
    But,...I found a crab. It around 1/2". grey with darker back.
    Claws are proportional (not big, not small) and black or dark brown.
    Legs are meaty and somewhat hairy.
    What crab is this?? Is it bad or good???
    I couldnt take a picture of it. It comes out at night and when you turn the lights on, if freezes and it looks like part of the rock. It blends in very good.
    During the day it hides in the cave in one of the rocks. Not under the rock.
    If I get a chance, I'll take a picture of it and post it here.
    If somebody has any ideas, let me know and I'll look'em up on the net for the pictures.
    Thx.

    Looks like a gorilla crab.
    Toss it into your sump. It's not reef-safe.

    Its not really black. Under water looks grayish. I took it out, it looks greenish. It has black or dark brown claws.

    Well, right now, only things in my 30g tank are snails, bristleworms, some tubeworms, aiptasia and that crab. I'll leave it in untill I get my 50g.
    BUt I would still like to identify it.
