Ok can you take another pic of your screen w/ the lights on -- from the pic I see now it looks like you have a fine mesh and that is blocking 30% of the UVB rays -- you want to unobstruct it either by taking the screen off -- cutting a hole for the UVB to get thru or place inside the tank -- 12-15 inches directly above his basking decor --- w/ the glass surfing I would get him out as much as possible 2 hrs a day or every other - see if this curbs the glass surfing issue -- and your temps in the tank are 95-100 taken w/ a digital probe thermometer for surface --- 80's cool side of tank? those two will make a dragon glass surf if they are too hot in the tankThe thing is financially, I can't right now. I just bought the tank i have now because the other one had broke. So I'm honestly gonna have to wait for money to be a lot better until I can upgrade and that may be months from now . My UVB is Reptisun T5 HO 24W 22" 10.0 UVB, its a long tube. I will send a pic of its location on the tank.
