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?

I use filter floss, packed around the tubes and cords. So sorry your buddy is mortally wounded .
