Hi, my 7 mo old has been scratching the sides lately and I just wanted to make sure it wasn't because of a lighting issue. I attached a pic of the viv but his reptisun 10.0 T5 HO bulb is in a reflector and is about 11 inches from the basking spot. Hot side is 105F and cool side is 88F.
As dragons get older they dont want real hot temps- its better to offer them a gradient heat like 95-100 --- a piece of decor that offers different sitting positions is good -- the UVB could be too close as well distance for a T 5 should be 12-15 inches --- all this could play a factor in the surfing as well as the weather --- its really hard to tell -- mine wants out about every year in the spring he starts in Feb and goes till March --- he too is in a Zen tank ---
