Tiny crab

Just doing my usual. Looking at the rocks after lights off and I see a tiny crab. Don't know what type
.?

Remove or not?

That is a type of commensal acropora crab, they live in the crevices of a colony and keep pests out. That type specifically is known to sometimes eat the polyps though, but I would just feed the crab directly, because they are so cool!
You can remove it if you want, but it may be cool to keep! Definitely remove it if it starts doing damage though.
Good luck, and God bless!
