Is this a shell Rot ? These spots are on both side ? My friend shared the pictures with me this evening ? Is there anything to worry about ? The tort is not kept in very humid environment..and the temperatures ranges around 26-32°c..soakes are given twice a week..age unknown.. length 3.5 inches...
No. Shell rot is from a tortoise sitting in poop/pee/wet substrate all the time, and to that end, it ALWAYS occurrs on the plastron, not on the carapace.
That just looks like a little scrape or injury and nothing to worry about
