I keep my Caramel albino's in a dark corner in my basement. I keep the window open so it gets cold but not freezing. I have been cooling them since October. First I stopped feeding them and reduced the light to only 5 hours a day. In November I moved them into the dark corner with only ambient lighting from outside but thats VERY little if any. I took the temp. with a temp gun and it was 51 degrees today with it being about 20 outside.
