Is my mystery snail dead?

I got him from PetSmart on this past October. He lives in a roomy tank with a filter, heater, and my betta fish, and he has always had enough to eat. Last night I observed him floating at the top of the tank, near my plant. When I got closer I saw that one of the plant's leaves was actually stuck in his shell. So I got the leaf out of his shell, and he was still floating at the top. I went to sleep, and this morning he was still there. So I took him out of the tank, thinking he was dead. But then I wondered ifhe was really dead, since I could see that he was still in the shell, or at least part of him. I put him back in the tank and this time he sunk to the bottom. Now I'm waiting to see if he'll get out of his shell. Should I be worried? Did the plant hurt him? Should I just take him out of the tank now so he doesn't pollute the water?

I don't see his "door" at the entrance to his shell

Do you think I should quarantine him for a while?

Same thing happened to me. It floated for a day or two then sunk and his skin bubbled.
If he's big then it was probably natural if you put any treatments or did a water change something could've gone wrong and you might want to look up some info.

Take him out and poke him if he sucks in fast he's healthy of there's no reaction he is I'll and if he is hanging out of his shell he's most likely dead

He is probably dead. My snail stayed at the bottom and then floated to the top and the skin fell out of the shell. Take him out IMMEDIATELY and also take your betta out. Clean the tank really well and maybe add some medications so that your beta does not die.
