Poor tortoise... That is definitely not a suitable enclosure. 1. I don't see uvb bulbs or heat bulbs or any bulbs for that matter 2. You need substrate for the bedding look into fine orchard bark or coconut coir something your tortoise can dig in 3. I don't see a water dish or any food! You need water there for him 24/7 and food should be giving every day! 4. That is a small cage you need a bigger one 5. You need hides in the enclosure! For your tortoise to get away if it wants to rest! If you can. Of afford/get or want to get these changes I recommend you re-home your tortoise to an experienced owner!. And by the way is that a Greek tortoise? It looks like it. But make these changes ASAP or you tortoise may die!
