Sorry, I'm back again with more problems.
I just got home from class and I checked my snail like I always do and he was lying at the bottom of the tank half out of his shell not moving and all shrivley looking. It didn't look right to me so I tapped on the glass a little and he didn't move at all. I started to get really worried so I got my net and lightly poked him. He at least moves when I do that, but he didn't at all this time. So I scooped him up in the net thinking once the air hits him he'll go back inside, but he didn't which I thought was really weird. I know that they supposedly smell horrible when they die, but I smelled him closely and he smells normal. Is he dead? Or could he be in a deep sleep? He hasn't been moving around a lot lately like he usually does and he hasn't touched his food in days. I'm so worried. Please help.
