I did a little research. And must be Xanthid spieces. Aka toliet crab

I had an evil crab that was attacking my fish and ate my devil's hand coral, had to pour hot water on the live rock to get him out. He was evil :twised:

I want.... haha. Dammit, why you not in GVRD.

Get Titus to ship it to you if you are willing to pay shipping haha.

Lol. I thought about putting back in sump but my luck it'll get blowin into DT

Looks like a crab in the Chlorodiella genus to me. Which is in the Xanthidae family.

Gorilla crab...evil little bastards!!

i would say xanthidea crab as well , same familly as emerald crabs . I had some big black ones that where harmless .The spoon shapped pincered crabs are usualy ok.

Not trying to cause any problems here. But be aware emerald crabs are in the Majidae family, not Xanthidae. I would also suspect the big black emerald crabs you have are likely Chlorodiella nigra instead. Here is a video on youtube so you can compare.
