Crab shell ID

Hi guys, found this in my nano this morning. Must of been in there a while as I haven’t added anything in ages and no rock or any large colonies added in a couple years.
Thanks guys!

Looks like a gorilla.
Remove immediately.

Not sure how to lure it out.
I guess keep your eyes peeled.

I’ll probably make a trap... it’s worked in the past for catching pesky shrimp
