I found one of my nerites upside down a few days ago and of course I quickly righted him but ever since then I keep finding him upside down. Maybe six times in the last few days. He was in a five gallon tank but I put him in something smaller (with a calcium source) to better keep an eye on him...
Tiny brown snail with no operculum, left hand twisted shell, and conical shape. I think it is in the Physidae family, Physa species. I would like to know what it eats and what will eat it.
