A few questions I need to get straightened out...

The probe on my digital thermometer, should it be placed underneath the hide and underneath the substrate, or just underneath the hide?

Is it safe to have a heat lamp sitting directly on the screen top, I have done the foil treatment and I need the lamp to keep my ambient temps up...

Should the lamp be on the hot side, the cool side, or in the middle?

It seems like my snake is spending a lot of his time on one side of the tank...but my temperatures are fine. Is he retarded? lol. Nah but he spent the majority of the day on the cool side until I moved the hide to adjust my placement of the thermometer and that disturbed him so he moved.

Thanks
