Most pets stores, not all, only know basic lizard care while chameleons are more complex. Common mistakes made because of pet store staff is telling customers to use night bulbs, glass tanks, water bowls, and coco fiber or other substrate. All of those are completely unnecessary and pose health risks. Chameleon need darkness to sleep that's why you don't need a light bulb. Glass tanks which I see you are using aren't pod unless it's an exo terra which give good ventilation, the problem is that for a veiled you have by the largest one to accommodate the chameleons large size so that's why people get less expensive screen cages because exo Terra's can get very pricey.
