What is this?!

Hey guys so i found this guy again after a long search (many nights). Have no idea what this is and actually don't understand how it got into the tank as I started with dry rock and i dip all my corals. Anyways I'm sure it's Reef safe because till now I haven't seen any coral or invertebrates dieing / damaged. Her are a few pics. Pretty cool looking critter IMO. Anyone know what it is?
Thanks guys

Looks like a Stomatella snail.

That's the coolest Stomatella I've seen!
