Help with hitchhiker ID please

Just noticed this critter on the glass of my sump. Recently received a small rock order from TB saltwater so I'm guessing it came in on those. Good guy? Bad guy? These were the best pics I could get due to the angle

Looks like a fleshy limpet eats algae but can sometimes bother corals, if it is in your sump you should be fine because there are no corals in there

That was my thought too. Just wanted to try and confirm. I'll let him be for now. Lol
