Cool dude of unknown species that i’ve found in salad! Advice needed!

Hello! Found this beautiful snail in my salad package and I want to keep it as a pet. I’ve already read some advices about how to keep one so for now he is chilling and waiting for special turf and cuttlebone! Any help identifying its specie will be appreciated (i guess it should be quite common) as well as some food recommendations! I gave him banana for now.

For size reference this boi is about 3-4cm long.
