Look at the nice big bellies. My sister's Lacy hasn't grown much in the past few months. We've been trying to bulk her up. Roaches, mealsworms, silkworms, whatever she can get and still no gain. The beardies natural habitat is the sandy plains of Australia, so I should hope they can handle sand. Lacy is on the all natural paper towel substrate. The only thing we never do is mist the cage or offer standing water in the cage. She gets water outside of the cage each day. I don't understand how so many sites tell you to mist them daily when breeders say misting is a major cause of illness and death for beardies.
