Small crab identification please! Good or bad?

[WarmSensations]

Noticed my GSP was closed up so I took it out for a lugols dip. I noticed there was a small crab I've never seen before so I wanna know if it's the cause of the closed coral.

It’s not a gorilla crab if that’s what your wondering. I’m not sure what it is though.

Looks like a crab in the Xanthidae family.
