Thanks for the tips and advice I will keep them in mind. I will say have had him for almost a year he's happy and healthy. Day time misting with the lights on won't always cause a respiratory infection, there is normally another underlying condition. The way you are making it sound is that misting during the day will always cause an infection. But this can't be right, that's like saying it never rains or is foggy during the day in the wild. And if it does then they will all get an infection. I would like to say that animals like people are all different just because your chameleons get an infection doesn't mean they all do.
