I have a 3 yr old mississippi map turtle. Today I noticed a large piece of his shell floating in his tank. When I saw his shell, I noticed that a large portion of it has come off. There is hard material underneath what has peeled away, but it is a darker color and I'm worried that he may have shell rot. Is it normal for a turtle's shell to come off in this manner? Should I take him for another visit to the vet?
Any help you can offer would be appreciated. I'm worried about him.
