haha, it does like he's whistling or something. or pursing his lips in judgement at me. :p i am still wondering if he'll stay cellophane/clearish or keep getting darker, i'm glad he's getting healthier but i do love that most of his color comes from his blue and coppery iridescent spots right now! thank you guys again, i'm bookmarking this thread so i can remember everything! yes i have been leaving the light on because the air temp is about 62 degrees here at night in the warmest part of the house, and the space heater only helps so much; but if it's a problem i will try one of my snake's infared night basking bulbs now that i have the thermometer and can adjust it to make sure he's not getting cooked. i think my spare summer bulb is a 150 watt which throws off quite a lot of heat.
