Answer
Hello Mikey,

Well, I do have a few questions for you & do need more information.
What type & brand of UVB light are you using, is it a flourescent type of light or a compact or coil light?  How close is the light to him?  
What type of basking light are you using, a bright white light or a colored light?
What are the temps & how are you measuring them?  
What sized tank is he in?  
How long has he been acting this way & had this more aggressive behavior.

Please answer these questions for me, thanks.
