Not a great pic but you can just make it out behind the hermit.

looks to be some type of gorrilla crab. cant tell too easily though since i can only see the claw and part of the sehll. not a good crab though. and a fish eater.

[Germanman]

yea form what i can tell doesnt look so good. try catching it and then taking a pic of it in a jar

[lotuskid]

Here's a better pic of him not looking v happy now he's been caught.

[Fishieness]

yes, gorilla crab.
get rid of him, or put him in a fuge where he wont get a hold of fish and corals.

:eek: :eek: :eek: is a emrel crab bad 4 a reef tank. tell me if it is cause i just got 2 of them

[Germanman]

emerald crabs, Mithraculus scuptus, are usually beneficial to the reef tank....although like all crabs they are opportunistic feeders and will sometimes pick at things u dont want them to pick on if they run out of there favorite food, which is algae. to answer ur question cully.
but i agree thats a gorilla crab and im afraid it will be nothing but trouble later on....remove it humanly please.
