Just noticed random sea slug in tank

[myles4miles]

It’s the thing next to the snail

It looks like a snail without a shell, kinda had a little somthing on his back maybe small shell idk it moving around and eating like a snail.
ITS NOT A CHITIN? More slug slimy no armor
What is it? I’ve never seen it before.

Yes, of you have multiple they will likely breed aswell!
Never heard anyone complain about them taking over tank, unlike freshwater snails.
