it is the Physa genus of snails if anyone is curious.
That's a nice tidbit of info
I had no clue they could survive without a shell, but luckily shrimp usually get to them when they're shell-less.
I've always been a proponent of let them live in peace lol. They are not harmful to plants, and if you feed right, they'll not over reproduce!
