Well the snake's about 18 inches and I have him in a 20 liter tank with a heating pad on the side, and I have a heat lamp that I turn on sometimes. I have a thermometer (sticker) on the back of the tank and it usually stays at 80-82. I'm using Fir Bark for the bedding. I haven't noticed any mites on him or in the tank, and he hasn't shed yet, and I feed him every thursday. He eats thawed pinkies, and he eats them right away every time. Is he supposed to have shed by now?
