I wouldn't feed your Cham wax worms there just pure fat there not good for him at all, also I do disagree that plastic leaf holds water better, it sticks around on live plants a lot better an the positives with live plants are better humidity, shaded areas, more climbing room, the soil will also soak up some of that extra water and I don't no how damp that base gets so I Carnt say for sure but be very carful with that as mold can soon come an also damp air may cause a infection to you chameleon
