Personally I keep a diet of mostly two things. Crickets and mealworms. I feed them every day but you can go every other day, I recommend about 6 a day or 10-11 every other day. I give them one mealworm every other day as a small treat, but be careful how much you give them because mealworms are very high in fat. Hope this helped
Diversity is the key! Try different good quality feeders and then feed what the cham likes.. Stay open to other feeders as your Cham may stop eating one thing all of a sudden. Crickets, roaches, horn worms, Phoenix worms, silkworms, mantis, and even some safe wild caught bugs can add some good diversity (flies, spiders, bees, moths). good luck.
