Thanks for your help. I think the setup is working fine as the male is very healthy and feeding/digesting well and slightly over a year old. I'm not sure that I want to mess with what is working. I did read everything you wrote in care sheets and don't dispute it at all but I'm trying to create as natural an environment as possible for the animal. The enclosure is screened rather than glass, that is why i have both lights (live in Ohio). In a natural environment animals burrow under the ground to get away from the heat (or hide in a cool enclosure), that is why i don't want to use a heat pad under the tank. I think the humidifier is necessary as my whole house furnace is on and can dry out the air and without glass to hold in the moisture in I'm afraid it will drop the humidity level too much. He was extremely active last night and actually curled up on top of his enclosure directly under the heat lamp for a while. I think I will provide a hide on the cool side as you suggested. Thanks for all of the help.
