| Floating Snail? Hey, so somehow, one of my pond snails has learned to float. I don't really understand it. The filter keeps pushing him down, but he keeps floating back to the top of the tank, where he turns himself upside down (with his body against the miniscus of the water) and floats around. I tried pushing him to the side of the tank so he can grab onto the wall, and he can grab on, but he always ends up floating again.
How is this happening? I thought maybe he might have an air bubble in his shell, but then how is he keeping himself upside down?
