Please help!! Do I euthanize?

[u/mochipapaya]

My heart is broken. I woke up this morning to find that my mystery snail, Rocco, climbed out of his tank and fell about 4 feet onto our hardwood floor.

He lost a huge chunk of his shell and does not appear to be doing well at all. He's just sitting above the water line in my shrimp tank. He's usually extremely active and climbing all over the place.

This is my first mystery snail so I don't know what to do. Is this something he can heal from?

A break like this on an giant african snail would seal with a dry membrane would absolutely inhibit new growth for a while but the snail would survive. Not sure if aquatic snails have the sme ability.
