Hi i have bought my new veild chameleon about a week ago and i have been struggling to keep the temperature around 85'f during the day and 75-80 at night. now because its so cold out side. its night time right now and i have 2 bulbs on him right now and the tank is sitting around 60-65'f will this harm him, he seems happy and content and he is sitting on a vine sleeping in the middle of the terrarium, well a little less then the middle of the tank. he eats a about 4-6 crickets the first few days but hasnt had as much lately. will he be ok??
