khriistian Posted May 29, 2013 Share Posted May 29, 2013 It looks like an Emerald Crab, and I have him for like a year now I think... He have a whole cave system in there but I recently started adding coral to this little tank and I have seen him more active since... Like walking around the live rock like never before and he found like refuge in this Yuma... I know emerald crab some people would say that they are bad and I believe this one act pretty much the same. I would just like to know if someone have one or know something about them? The would eat corals or not? Link to comment
The Salt Posted May 29, 2013 Share Posted May 29, 2013 They have them but I have never seen them. 'Ruby Red Mithrax Crab' same thing? Link to comment
Gramophone Posted May 29, 2013 Share Posted May 29, 2013 Don't think it's an emerald. Read this: http://www.chucksaddiction.com/hitchcrabs.html Link to comment
The Salt Posted May 29, 2013 Share Posted May 29, 2013 Don't think it's an emerald. Read this: http://www.chucksaddiction.com/hitchcrabs.html Looks like the first Mithrax in your link? Link to comment

Voodoodol Posted May 29, 2013 Share Posted May 29, 2013 Looks kinda like a strawberry crab to me. If that's the case it's ould be fine in your tank. If it's a red emerald crab it will Lao be fine. My emeralds gobble up cyano,bubble algae and any algae growing on rocks or sand. Link to comment
login Posted May 30, 2013 Share Posted May 30, 2013 My guess is a type of Pilumnus. Maybe Pilumnus longicornis. http://decapoda.free.fr/illustration.php?n=4&sp=2206 Where did the live rock come from? Indo-pacific? If so, this cannot be an emerald crab, because they are not found in that region. If an lfs has emerald crabs already, they can hitch a ride on live rock if the live rock is in the same tank as the emeralds. The claws should be a good clue. The claws of an Emerald opposed to a Pilumnus are very different. Also the carapace of an emerald are a pentagon shape, while Pilumnus have a much more rounded carapace. Link to comment
Islandoftiki Posted May 30, 2013 Share Posted May 30, 2013 Is it like this one? I have tons of non-reef-safe crabs, and none of them ever do any damage to corals. If you're comfortable that it's not eating your corals, then enjoy your little friend! It's a cute one! Link to comment
lakshwadeep Posted June 1, 2013 Share Posted June 1, 2013 It looks like a Xanthid, which have oval bodies and often dark pincers, like in the pic above. Link to comment
