Your turtle has little black spots on his shell one already died from the spots on his shell is he sick is he dying is he too old he is a painted turtleand no he is not literaly painted?

this could be a sign of fungus or shell rot starting , to be sure find a vet that specializes in reptiles, most vets don't know much about this. also antibiotics can be prescribed. i work at a large pet store and have one with shell rot it is a long procedure to get them healthy. I am going on 7 months and and finally seeing his shell looking better.
