I agree with above posts

Definitely a Porcelain. Feeds on microfauna and algae with those little "feather mitts". A kick to watch feeding and completely harmless. If you have any 'nems in the tank don't be surprised to see it snuggled up near the foot, or even on the tentacles. They often bond to them for protection. One I had years ago would actually feed my carpet 'nem little pieces of silversides the 'nem missed.
