Matt, you really need to read up about keeping bearded dragons, it doesn't sound like you are really sure about what they need. It's really really important to do this because reptiles aren't like other pets, they can and will die if not kept properly. Your dragon isn't eating because it is not in the right environment, and it will lose condition very quickly at that rate.
Does anyone know of a caresheet?
Matt, can you post a pic of what you are keeping it in for now?
