the only one i have at the moment is Calci w D3, twice a week, as far as when my bf feeds them i dont know prob about the same. i told him we really needed to get on a schedule with all the supliments.
How old is your chameleon? A young cham needs the feeders dusted with a plain calcium dust (no D3) at every feeding (Adult everyother feeding)
Calcium with D3 twice a month and a muiti vit. once a month.
