Crab Id Request... Can't Tell If It's The Emerald I Added Years Ago

[Quartapound]

Hey guys, I've seen this crab a few times after the lights go out, that's the only time he comes out, I did add an emerald crab a few years back, but suspected him of picking at stuff so he was banished to the sump. After moving this summer I took some of the rock out of my sump and put it in my display, forgetting that it might have contained a crab. Although I'm not even sure if this is the same one, or if it's an emerald crab at all. Managed to get a good picture of him this morning, any ideas or suggestions?

Yes Sir, I believe it is.. They can get big and they like to wedge themselves into a crevice. Green and fuzzy

Looks like a emerald to me

Looks like an emerald to me too.
Have you lost anything recently you can't explain? Might need to banish him again

Thanks for the reassurance everyone, lol, I haven't really noticed anything negative happening lately, it was more of a surprise to find him in the display tank than anything else, I actually forgot that I had added him because it had been so long ago.

when they get big and have not much to eat, it may catch a snail or two.
