Help!! I have a 3 year old bearded dragon. He has always had a very healthy appetite. Recently, he has stopped eating. He is not impacted, he is well hydrated, temperatures are good, brand new uvb and heat bulb. 40 gallon tank, about to move into a 90 gallon. He hasn't shown interest in food for a week, and is being very lazy. Could this be brumation, in the middle of August?
