I have a electronic thermometer that measures humidity and both temperatures on the sides of the tank, as well as a thermostat connected to his heat pad under the tank that is normally kept at 89-90 during the day then 80-82 at night on one side. The humidity is reading about 50% and as for lights, since I have the heat pad, I keep his tank close enough to the window so he gets daylight without getting direct sunlight, I figured that'd be best. He is currently in a 10 gallon glass tank with all but 1 side blocked so it looks enclosed, and the top has a mesh screen.
