Anyone ID this crab please!

Hi Everyone! I'm cycling my tank and found a couble crabs (about a half to one inch wide) that hitchhiked along with my LR. Any thoughts on what type this is? I was thinking Emerald based on what I saw at an LFS, but am not 100% sure. Thanks for the help! Tim

Thanks for the ID. That looks a lot like him...except the 2 I have look a little more hairy. Also mine do not have any muave coloring....perhaps juvenile? There are grooves along the back side, but not as pronounced. I guess I'll have to try and trap the other one. I only got one so far.

Actually, I think it might be a Daira perlata (Herbst, 1790).
