Yep, collonista snail.

I'll third that. Love those little guys. Multiply nicely and if allowed will pretty much take over cleanup

They go where nothing but worms can reach. Their other name is 'strombus grazer' and they seem to be related to the conch.

Actually, they're a species of trochoidean snail. http://www.reefkeeping.com/issues/2004-05/rs/
