Anyone have any idea what kind of crab this is. Bought some cured LR from a friend and he came along for the ride.

Looks like an Emerald crab

The picture does not really show the true color, but the crab is grey

Hmmmmm Not an emerald then

Look similar to these except for the color?

Porcelain

Steve, I have several of these also and the first thing I thought was the claws look like a porcelain crab. But, I've seen them picking off the rock and have yet to see the filter appendages come out to feed. Is this crab a threat?


Sorry for the threadjack ajg1460.

More than possible it's a species of porcelain. They will not always be filtering the water and they do eat algaes.

The flat broad claws are usually a sign of being at least "reef friendly"

Awesome! Thanks Steve.

From the pics I don't thing that's it (Porcelain) . On the back of the claws it's jagged not smooth. Wish it would come out so I could get a real good look. Claws are small and I have seen it picking hair alagee from in and around plops. No problem threadjacking helps us all learn

Have you been able to get a look at the carapace shape and if so can you decribe it?

Cheers
