Help! My baby snapping turtle's shell is.......flaking off. He looks puffy like he's fat and his color is a bit.....off. His shell is kinda peeling like skin. Does anyone know what this is or what I can do to save/help him? The only thing that has changed is that he has been in a container with stagnant water for maybe a week now (i'm borrowing his 10 gal and using it as a hospital tank for some of my angelfish). He's eating alright, he's responsive, and besides the shell and the puffyness he's fine. Any help would be greatly appricated. Thanks!
