Hello! I'm very new here and I just need some reassurance and advice. I got my fire skink a couple weeks ago and he seemed to be doing fine. But just last night and this morning he has been sleeping onto of the substrate when he usually burrows. I went to go see if he would wake up and he was really limp when I held him and his eyes squinting open before he went and hid. I'm very worried (the temperature and Humidity are fine in his cage and he is eating mealworms and crickets just fine) Thank you for any and all info you can provide!
