...depending on the size of both cham and cricket. At five months old, I would expect he might eat 8-10 1/2-3/4 inch crickets (depending on his own size). My guy had reached close to adult size by 7-8 months, was on 1 inch+ crickets, and as the growth had slowed down, so had the eating (maybe five a day, and maybe not eating every day). It's good to vary the mix a bit with some other bugs - he's probably a little small for superworms yet, but silkworms, phoenix worms, waxworms (yeah, I know they're fatty - the Big Mac of the chameleon world - but they're a good size for smaller chams, and they do love them - only an occasional treat, though), roach nymphs, etc. are all good options. When mine was growing, I'd try to give something other than crickets twice a week.
