Nice looking cage!
Just some comments....there is a very good chance that the health of one or both will suffer if you keep them in the same cage. You may not see any apparent signs at first...but they could also go so far as fighting. In the wild if two meet up, they have the option of moving far away from each other if they chose to. In a cage, they can only move so far.
Do you have a proper place in the cage for the female to lay her eggs? Failure to provide one could lead to eggbinding.
You don't need any light at night as long as the temperatures don't go too low (low 60's). If the chameleons can see that type of light, then it will likely keep them awake.
Are the basking lights outside of the cage so that there is no chance of the chameleons getting burned?
