I’m a new owner and I’m concerned with my dragons sleep. The temperature in his tank continues to drop at night to about 70 before I go to bed but since it continues to drop... I turn his regular heat lamp back on cause hes still considered a baby. I’ve only had my dragon for a couple of days. I don’t have another heat source at the moment. Am I going to hurt him? I don’t want him to be exhausted..!! Because he wakes up when I turn the light back on. I’m worried. Can someone give me some peace of mind please
