Urgent help needed

[langers2004]

I have a young yemen chameleon. I have him in a 1metre tall flexarium.

I was under the impression that id turn the light off overnight. Its a mercury vapour one. Is this right as i just thought there is nothing to hold heat in at all being a flex.

Dont want the little guy getting too cold. I have my heating on 22c in the day so it cant drop below by a lot at night really?

Heat could be about 26.5c/80f in the day (under the lamp), let it cool at night but not below about 16c/60f
If it does get colder than that, you might want to consider a dark bulb or ceramic, or simply warm the room itself overnight. A drop in temp is natural and the liz requires it for good health. Turn your mercury lamp off at night, darkness is important. Cheers
