Hi,
does he ever get his colour back even if for only a few times or, he is always without colour? Also, I not sure I remember well what you wrote in your previous posts; is he all dark or light colour when you say he is without colour? (Sorry if I ask information you have already sent).
I see my male, Skipper, sometimes wearing a wondelfull marbled jade green (he's a calyptratus) at night, other times he is completely pea green with no marbling and as soon as he sees me (I used to spray his cage and he never really liked it..!) he turns dark, I mean dark that you cannot say he is green anymore, right away..I know it's my presence (thank Skipper...) and he is doing well otherwise, he is just more shy than other conspecifics.
If he is eating, drinking and passing...also in his new set up, probably your cham really doesn't like anybody's presence...since they are so "asocial" that could just be it.
Does he has a lot of foliage where to hide in? Is when he feels secure and safe in the foliage that my male cham. doesn't display any aggressive or stressed colour most of the time.
Hope this help a little, I know you have been concerned about this for a while now.
Chiara
