Hey guys, I am a new chameleon owner of a 3 week old veiled chameleon. I have had him for 3 days and so far he has been doing well as far as I can tell. I've watched him for a considerable amount of time and he is eating crickets, drinking some water off the leaves and moving around quite a bit. Today, however he was walking on the ground of the aquarium along the walls which I have not seen him do before. I noticed that his skin was very dark and patterny which is not a good sign. I assisted him back into the branches and his skin went back to the normal color. However while he is climbing on the branches he often will stand up and put his arms against the glass as if to climb it and his skin will sometimes go dark. I am wondering if perhaps he is trying to get out or if he is seeing his own reflection in the glass. The pet store owner said that it was okay to keep him in a glass cage for the first 6 months until he gets too big for it and then I should get a mesh one. Another thing I have noticed is that sometimes only his head and legs will change color. I am wondering if I am doing something wrong, I have the temperature at about 76 and bring it down to 65 overnight. He has plenty of food, and I mist many times a day, whenever the leaves are not moist. He has a lot of branches and leaves to hide in.
