You have any coral in the tank?
It's not a nudi. It's a chiton and it's not reefsafe. I forget the species off the top of my head but it's definitely not safe.
That's the first I've ever heard that Chitons are not reef safe. From most of the blogs I've researched, the consensus appears to be that they are fine in most home reefs (they are algae grazers, although they will slowly consume your coralline algae).
Black Keyhole Limpet. VERY cool animals. They can get large. The worst they'll do is knock over the smallest of frags that isn't firmly attached.
