ok well since we are on the subject of stupid questions.. i have noticed that my snake tends to go back and forth between the warm and cool side...but has been stayin on the cooler side longer and longer... the temp in the tank did change when i put my heat on.. so i lowered his back so it will get stable again.. but he stil remains on the cool side... sorry for all of this.. its just that i know nothing but what i have read about them and just want to make sure hes ok
