I just realized that my turtle (3 year old RES) is shedding quite a bit. Not his shell, but the exposed skin on his neck, etc. Temp in the tank is about 78-9, and I did turn it up recently because it had gone down to 70 (tank is next to the window and it's cold outside!). He's also been eating A LOT recently. Problem is, if I don't feed him 'enough', he's discovered that he can EAT the ZooMed Turtle Dock that he sometimes basks on. So I need to ge a non-edible dock (btw - I think this dock is really bad -- the material it's made of seems to constantly flake off). But beyond that, what causes the shedding?
Thanks!
