the care sheets say about 80 to 85 right??? im not sure because im not a breeder either but yeaI'm not a breeder, but I thought baby chameleons weren't supposed to be kept with any heat? Just around room temp or so? Someone correct me if I'm wrong.
Also I wouldnt even consider a nighttime heat source unless it dropped under 50. My cham room regularly gets to 50s and the Parsons even occasionally high 40s during winter.
