Hi everyone. So I rescued a Russian tortoise yesterday and I'd like to get all your opinion. His shell to me seems in poor condition and I'm not sure if it was from his diet (only lettuce) or what. I only say it's in poor condition because it isn't smooth. And looks like it's flaking up and pyramiding. Any suggestions of what to do for him? i was told he was thought to be 7 or 8 years old. The people I rescued him from had him for a year and a half.
