Those look like Collinista snails.

Collinstra for sure. I have a 150 and most likely have thousands of these guys. They are only out at night but the wrasses I keep love to eat any left on the glass in the morning. Great free cuc IMO, plus way less creepy then worms

Ps to get the snot snails I just fill their holes with super glue. Quick and most of the time works.
