Can you help me? I noticed this for a while, but I thought this wasn't really bad,but now I'm worried. There are so many white lines/spots on his shell. What is this and what should I do?
Thanks.
There's nothing wrong with your tortoise's shell. That's just dust and debris stuck in the cracks. After a nice soak, if you scrub it with a soft bristle brush, you can get all that out of the cracks and he'll be good as new.
