I have a 3-4 month old male veiled who is pretty consistently brown since he moved into his bigger enclosure. He is active and eats like a champ but his coloring is worrying me. Ive read that darkened colors is a sign of stress so I've kept the room he's in quiet and free of heavy traffic but there has been no change. He's been in the new enclosure for three days. Could this just be new cage nerves or something more serious? I'm new to chameleon husbandry so I want to make sure I'm doing this right!!
