My young adult male veiled chameleon will eat hornworms and crickets but he won't take meal worms I have never seen him show even a little interest. I have tried silk worms, butter worms and Phoenix worms. He will only take crickets and hornworms. He only started taking hornworms the past few months. Should I be concerned about his lack of interest in the other worms? I try meal worms every now and then but still nothing. I haven't tried anything else in a while should I try other worms or just give up? Also does anyone have any ideas on how to get him to show some interest in the other kinds of worms?
