Checked the tank this morning with a flashlight and ran into an urchin! I did not put it in there so definitely a on my live rock

any idea on what kind it is? Should I be worried about it?

it looks like a short spine urchin. I have one in my tank.

No. You should not be worried, they are very beneficial as part of your cleaning crew.
