That is a very beautiful enclosure. I don't know anything about pancake tortoises except they are very cool looking I was surprised that there's not more dirt in the enclosure. they must originate in an extremely rocky climate I'm assuming. How big is the enclosure?
Generally these creatures are found in rocky hills and outcrops of the arid scrubs approximately 100 to 6000 feet above sea level. One can spot them in the dry savannahs or flat grasslands home to tropical and sub tropical areas. They are specifically familiar in hillsides characterized with rocky outcrops or kopjes of the arid scrub.
Pancake Tortoises are also observed to inhabit semi arid deserts with scarce vegetation.
