my babies ate about 12 small crix a day, depending on where you get them. if you are getting them from a pet store you most likely are getting variable sizes, so feeding numbers will be up and down. Once the cham gets bigger you start feeding different and bigger feeders so mine only eat about 6 large crix and maybe a worm or two.
Use to be accepted that you offer as many as they want in a 15 minute period. once or twice a day. Morning feeding perferred to allow chameleon to thermoregulate and help with digestion in their daylight hours.
