Snail or slug?

[Samz]

I didn't intentionally put this into my tank. I actually thought it was a nudibranch of some sort, but it appears to be a snail. I can't find anything similar through a Google search of saltwater snails. If it wont hurt anything I will put him back in the tank, although I accidentally injured him when I pulled him out, as you will see in the second picture.

It looks like a stomatella. They're good clean up crew members like snails. The only downside is that skunk cleaner shrimp will eat them. They don't have as strong of a defense as snails do

Thank you, I will look them up. I didn't realize he had a shell until I got him out of the tank.
