dont feed mealworms unless you tear off their heads, otherwise they will eat up the inside of the leo. many will tell you this is an urban legend, but i have had many people give me their first hand experience including one person who only found out it was the mealworms that killed his beardy because thats what the vet said when he did a post-mortem. crickets and maybe occasional pinkies is all thats needed for their diet.
