Any idea on an approximate age? I was told 4-6 months, however, I was also told he was a greek by one person and a russian by another. So they apparently did not know much.
Your beautiful tortoise, I know for sure, yay for me, is not a Russian.
Maybe you can take a picture of the plastron (the underside), sometimes that helps the experts to be sure for you.
Love that little face, and the shell is lovely. : )
Age is tricky as growth is determined by many factors, my guess would be 2.5-4 years. Just an educated guess by the scute size. To get a better idea what is the scl (straight carpace length)?
Also if you have it on the bark bedding as shown in two of you pics you need to get rid of it. I used a layer of half an inch of eco-earth with cypress mulch on top. There are other options as well if you search the Hermann's section for bedding and substrate topics. The red bark doesn't hold moisture that well.
