my uro is just a baby, still just about 4 ins long or so. I have read slightly varying information so I'm asking here for another opinion, about nighttime temperature. My uro goes to bed about 6pm, and I turn the lights in the tank off about 9. When I get up in the morning, 6am, it's 68 in the cage and the slate he is sleeping under is cold and he is cold as well. This bothers me! Is this ok? I've read that it's ok for nighttime temps to get down to 65. Also, he doesn't come out or "wake up" until about 9-10am. So I hate the idea of him laying there all those hours "cold". Please let me know if I should be doing anything different. Daytime temps are about 117 on basking spot and about 85 on cool side. I've only had him since Tuesday morning.
