Thank you very much for you help. Based on what you said I'm going to have to adjust things as far as temperature is concerned. But.....why didn't my tort behave in such a "naughty" way in the past years? I wonder.My Greeks are used to surviving in temps of 48* c & over , Now we are down to 24-25 *c, most are now tucked up fast asleep , although some still make an appearance during the late morning when the sun hits their enclosure, its up to them . I reckon they have managed to thrive for millions of years without human intervention ,So they know better than me whats what.
