Wait what? Hes eating 20 to 30 crickets in one day? Woa, thats a lot. Wax worms are like the Snickers bar of the insect world. They are good and fatty, but too many are not keeping a healthy diet. I have not had experience with a cham eating 30 crickets in a day...were they tiny crickets? Any ways, at 3 or 4 months my veiled usually ate around 8 to 12 tops. Humidity sounds good.
