ID this crab!

Can anyone ID this crab? I know the picture isn't the greatest... sorry. I just noticed him the other night hiding behind a rock with some mushrooms on it. He's got a chubby body but his legs are so small I can barely see them. He's kind of whitish and spotted.

 

Is it on the bottom, between the rock on right and the mushrooms on the left, and back into rock space in the second pic? Because that looks like a stone crab variety to me, similar to one I had that came out of rock and I couldn't see his legs most of the time, the body was low to ground and legs tucked under

 

Yes...exactly. Do I need to get it out?

 

It looks to me like it has the body of some type of shame-face crab.

 

if you want shrimp, corals, slow moving fish, then yes, get it out just to be safe.

 

Agreed. Catch him and put him in the sump if you have one. He can clean up there.

 

Mine grew to about half dollar size and ate small fish and a bunch of snails. I tried trapping it by using a glass that was just big enough for crab to just walk into and not be able to get a grip to climb back out, put it down in sand near where I saw it hiding with a piece of shrimp in the glass. Due to size of crab, I had to take LR out and found the thing in a crevice in rock, then put rock in QT and used a glass to capture crab. Others have had success in DT just using glass trap.

 

I had no luck use traps at all. I also had to pull the rock out and it still took me 10 minutes to get the crab out of the rock.

 

OK. I was hoping i wouldn't have to... but in the sump he goes! Thanks alot!
