So my cousin has a bearded dragon which he got in May on the 26th of this year and I don't know the age but he got him when he was little so I'm guessing he's around 7 months old maybe? Maybe a big older but my cousin said he hasn't been eating, he's not very active and that he's been going to sleep early, around 3 PM. I am not sure if it's because he is going into brumation since it's getting colder or if it's the size of the tank. I've been telling him he needs a bigger tank since he has a 20 gallon and his bearded dragon is WAY too big for it. I got my dragon on August 14th and he is eating fine and he's going to sleep a bit early but not as early as 3PM (More around maybe 8-9PM sometimes later) and he is very active. Does anyone know what could be happening?
