2nd Urchin and possible emerald crab? - Aquarium Advice

jamal-188 · 11-02-2003, 04:12 PM

I have another urchin that is unidenfied who is carrying around a little suction cup

and 2 pics of a crab that I bought at my [acronym:c8b20e29f1="Local Fish Store"]LFS[/acronym:c8b20e29f1]. The crab was in a tank with emeralds and I was told this was an emerald as well but it''s not green?

I think Reeflady is the expert on crab id.
Hopefully she will read this....

Expert? Eek - not.

It definitely looks like a Mithrax crab to me (commonly referred to as the Emerald crab). There is a species of Mithrax -- Mithraculus forceps - which is almost identical to the Emerald (Mithraculus sculptus), except that it is brown.

I'd say that's probably what you have!

So, in "theory" he should be reef and invert safe correct?

Yep - in 'theory'

, the crab's behavior and diet should be exactly the same as that of the Emerald.
