how are you feeding them to your chameleon, cup or free range? i read somewhere, not sure if it was on this forum or not, but it stated that they can get bored of the food in the dish easier or something like that. if i could remember where i read it from i could give you a better quote, lol. anyways try phoenix worms, mine loves them. he will eat the phoenix worms before crickets. you can also try hornworms if he is big enough to eat them. anyways good luck
