I only had one female given to me as a gift due to the large shipment I got.
temps in my home was kept at 68-74 degrees and the lone female was housed in an exo-terra that was misted 3 times per day. humidity was from 60% fully dry, to 80%/90% when fully wet.
since she was a full adult WC female (and not growing), I only dusted with straight calcium once a week at best.
she disregarded any large hydis, but loved 1-2 week old crickets and small mantid nymphs. she would sometimes eat houseflys. baby roaches were her favorite.
she lived for about 9 months in my care. I wish I got a male and another female at the same time so mabe by now I could have made them more avalable.
there is some good well writen info located in Peter Necas book "Chameleons Natures hidden jewels".
I hope that helped a little bit.
