Anyone have any idea what kind of crab this is. Bought some cured [acronym:b26d266c0d="Live rock"]LR[/acronym:b26d266c0d] 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

aquanaut · 03-17-2005, 09:54 PM

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
Steve
