Bearded dragons are cold blooded animals. Even though reptiles can last long with out food still feed your bearded dragon every day. There diet is crickets, meal worms and super worms, cale, blueberry's and mango. Well thats what i feed mine. But DO NOT feed them canned vegetables lettuce fire flies avocados rhubarb beet tops and spinach. you need to take care of one is a proper enclosure, giving it enough lighting, keeping the temperature high, and feeding.
