Need this slug look-a-like identified

[Treezer8]

So it basically acts like a snail..Moves like a snail..But looks a little different than a snail.

Instead of having a shell, it has like a small cover over its back, and moves around the tank sucking stuff with its mouth. I've seen it several times, but finally got a chance to get a good pic

I knew this guy would be good! Just wanted to make sure, and thanks for that!

Looks like hes here to stay. The first time I ever found him, I was moving a small plug with some zoas on it and it scurried away from me. Scared the hell outa me I think it was a coral-eater
