I have a new baby veiled cham and got his cage set up properly yesterday. Iv had him a few days and he is eating but only a couple crickets a day and a worm or fruit fly here and there. He just spends all his time at the heat source and won't climb down where the crickets in the dish are.. Help! i need some strategies! i don't want to let the crickets loose in the cage like i did the first day.
