Aggresive beardie

Question
I have an around 8 month old beardie that is very aggressive to me. I did a lot of things that should help the aggressiveness like when he is gaping i stuff a green in his mouth.

Answer
Your question was sent to the pool but I will now answer it.

Who told you to stuff greens in his mouth, and that that was an acceptable way to deal with aggression?

...and are you even sure you are dealing with aggression?

He may be regulating his body temp. with mouth agape breathing. If he's doing this all the time, and you dont have a cool side for him, or you are keeping him in a tank that is too small...you might just be overheating him.

I suggest you do some websearches and come up with some Bearded Dragon pages to read. You can start at anapsid.org under the lizards section.
