What kind of crab is this?

[Ryan Matthews]

This guy has been growing in my tank for quite some time. Fairly certain its a gorilla crab, but wanted someone to confirm this for me before I get rid of him.





What do you think? I know he's not an emerald crab, as I have a couple of those i actively put into the tank. Thank you for your help in advance!

No, it's not a Gorilla Crab; it's a swimming crab of some kind. The worst kind. Get it out.
