Help identify

[NMSREEFER]

I thought this was a snail without its shell. On closer examination it looks like some kind of slug eating a dead hermit crab. Can anyone Identify it?

It looks kind of like a Stomatella snail.

It is a Stomatella. That's his tail pointed toward the dead crab.

Right about the tail. I was watching him with a flashlight and he started heading for the hills. I also noticed my Royal Dottieback trying to make a meal out of him but he got away.

Thanks guys.
