My bearded dragon is suddenly aggressive and standoffish, it is summer

[Ghostlizard]

My bearded dragon, a 4 year old male, has been acting very aggressive, grumpy, and cranky the past few weeks. I got him last year from someone who could not take care of him anymore. It is may and I’m in the southern US if that helps at all. His beard has been black, he has made motions to bite people, and has just all around been very hostile. He has been eating, has had regular bowel movements, his temp in his tank has stayed constant. I have no clue why he’s like this, he is usually calm and loving.

The temp in the tank is what? How are you taking surface basking temps? And what are they? What kind of UVB are you using - coil or a long tube fixture? And where in the tank is it?
