Hitchhiker - is this a baby snail?

Can you help identify this hitchhiker? He showed up about a month ago and has been growing rapidly. He lives in holes in the rock by day; nocturnal / very active at night.

At first I was thinking this could be a baby snail, but the white stripe on the back confuses me. At the time he showed up, I only had Astrea and Margarita snails in the tank.

Stomatella? Harmless.

Yeah, likely a Stomatella. Need a better view of it to be sure.

Thank you both!

Oreo!

Photo number three looks like a possible Sundail snail to me. Take a look at that critter, and if that's who you decide it is, you're likely going to want it out of your tank - their primary diet seems to be zoanthids.

I can see that as well @Maritimer, the mantle going over the shell in the other pictures makes me think otherwise though. Worth getting a better picture to identify better.
