So I just picked up my Vieled Chameleon Friday night, I am a first time chameleon owner. Since I picked up up she has for the most part stayed a dark brown to light brown color. I tried fixing the heat but my room is naturally hot I am trying to keep her around 80F but with that I can't get a basking area. She is about 2-3 months old I have a glass screen tank with 2 open vents in the front it is 18x18 36 tall also the whole top is a screen. Her humity I have kept from 70%-90%. I opened my window shades so she still has sunlight but I am worried that I may be doing something wrong for her.... I also lowered her basking light to 40 watts from 75 but very time I turn it on she gets dark so I only keep it on for 2 hours after she eats. Is there anything I am doing wrong?
