every other day seems to be the best. in the begining your Cham may not eat... mine didn't eat for the first week and a half but them he went on an eating rampage!!! now he eats about 7 crix every other day and he gets a dragon fly about once a week. i have an anole in the cage with him and he gets to have the smaller crix and the house flys i catch and put in there. they even bask together, the anole will lay on my chams back.
