What is this?

Ok I need a little help here if anybody knows the exact name for this Nudi/Cowrie? I have a clients tank where they have multiplied like crazy and I actually dont know anything about this guy. I disected one and the shell is long and flatish. You only see a little sliver at all times.

 

ohhh shell is an oval shape also. Dosnt seem to pray on any corals or anything. Actually wonder what they are eating. Seems to graze on the rock.

 

Never mind is called a Scutus.

Glad you found it. This will give you some more information The Grazing Snails, Part II - Abalones, Limpets and Nerites by Ronald L. Shimek, Ph.D. - Reefkeeping.com

 

I've also had a huge population of there. Seem harmless detritus eaters
