I've had my dragon since February 2020. Earlier this week he decided he didn't want his salad, so to make sure he wasn't sick and was just being a picky eater, I offered him a Dubia roach. He ate that but still refuses to eat the salad. I feed him kale and mustard greens, alternating between the two each day. I tried mixing in some freeze-dried mealworms and that did work for a couple of days but now he's just flat out refusing to eat his greens, even if I put some mealworms in there. How do I get him to eat his salad?
