New here! I've got a hitchhiker I need IDed

[Lexi81]

Hi everyone! This is my first post. I have a hitchhiker that came with some live rock I bought and want to make sure he's reef safe. Can anyone identify him?

If that critter has a kind of undersized saddle-like shell on his back, that's a stomatella snail, a very good guy. But if he's all soft-bodied, that's either a flatworm or a sea slug, not a good thing. Wait for more opinions, just isolate him in a dish, and if that's a stomatella (I dimly recall they have antennae, which flatworms and slugs don't) put him back in and hope he breeds.

That's a Stomatella snail, I'm fairly sure. You can see the small shell on its back.

Another vote for stomatella, a good guy.
