Hi so I've had my russian tortoise Donatello for a year now and I've recently started to notice how his shell doesnt look as nice as other shells. I've tried to do some research but I felt like I was just getting my self worried about it being something really bad so I decided to come here and see if someone could help. I dont know if it's like shell rot or just from him growing but I wanted to make sure. Here r some photos.
