I find this discussion facinating...I feed my cham a variety of food throughout the day. Some days its a calciworm or two, 5 crickets and a small to medium dubia roach. Others it's waxworms, 3 roaches and a hornworm. At times he ignores the offering of a roach or other feeder but the next day or two days later he has a go at it. Some days he's only interested in crickets could be up to 8. That variety includes mealworms, some days he'd eat them non stop if I let him. But I offer 2 or 3 and that's it for a few days and then offer only 1 or 2 then, trying not to be heavy on the less staple items. Assuming too much of one thing would be bad for any animal. I may even leave a feeder off the list for a week then reintroduce.
I have wondered more about every other day feedings and every three day feedings. This seems counter inuitive to me. In nature they would eat daily and a variety of smaller/larger bugs we don't keep. Perhaps not amounting to the same volume but similar natural requirements. I free range my cham twice daily for 1 1/2 hours, during which he is very active. Are these feeding recommendations because most chams are kept in small cages without excercise? Or do chams become more sedentary with age? Or do they simply require less food because they are not growing as much?
