I have a new Veiled Chameleon, when I first bought him I had him in a 10 gallon tank, its was a little small but i wanted to make sure he was eating, and now that he's alittle older and eating ok I got him a bigger cage, but now he's not eating anything but crickets. before I could get him to eat mealworms, superworms, and waxworms but now hes not eating them. Should I be worried, or is just gettin used to his new environment ????
