I live in UAE, we found him some time ago near an open construction ready plot and thought we'd give him a home in our balcony. We have shifted apartments now and there's no balcony in this apartment for him to run around in. Given that we have a fair amount of space for his enclosure, how big should it be? Being above the minimum and quite below the maximum? Thanks for the help.Looks like Testudo graeca. Where are you?
I typed this up for russians, but care is similar.

You'll need a very large enclosure to house one that size indoors full time. And you'll need to do some research into what type of UV bulbs will suit your situation best.
