Do you help upside down snails

[rockies]

I have a new cleaning crew and I noticed one of my snails (turbo/astrea) had fallen off the glass onto the bottom and was upside down. I left him overnight hoping he'd figure out how to flip over and get around again, but in the morning he was still there (almost completely out of his shell). I tipped him right side up.
Would a snail in such a position (unable to latch onto anything) eventually abandon its shell? Would it eventually die?

Astreas and Mexican turbos can right themselves easily. I noticed this frequently shortly after I added them to my tank. They would often spend an entire day upside down. After they had acclimated (about a week) they right themselves very quickly.
There are a few species of snails that cannot right themselves and would eventually die. Snails do not abandon their shells while they are alive except in cartoons. Hermit crabs can.

I help my snails out when they are upside down.

They can acually drown if you don't help right them.

and if you have some mean hermits they will eat them for lunch. I always turn mine back over...
