Hello, I am a new time bearded dragon owner. I have had a male bearded dragon for about 3 months now. I have him in a zilla 40b tank. I use a 100w basking bulb and a 10.0 UVB light. The basking side of the tank is probably at 105ish (seems to change a bit with the heat outside). I have noticed that my beardie started getting picky with his food and puffing up his beard. He went from eating about 15 worms a day to ever other day now I can get maybe 5-8 crickets in him. Now he seems to not want to come out of his hide. Hes been hiding for two days now. Hes looks at me when I check on him.
He could be brumating . I am not very experienced with dragons (i just got my own this month) but from everything iIread tthat'swhat it sounds like. Do you have any pictures? How long is he?
I would monitor his weight. If it's remaining relatively stable he's probably OK. If he's acting lethargic and losing weight then it may indicate a problem. Good idea to double check temperatures and UVB exposure too. If that's off then it can cause them to act lethargic and hide or act up and glass dance.
