So i have one of those 34 inch reptizoo 39w t5 uvb bulbs with a reflector. I've read a lot about lighting and most sources say this is ideal, but sometimes I catch my guy pawing at the top of the cage right beneath the bulb and that makes me very concerned about if he is going to burn or isn't getting enough UVB. it's a veiled chameleon, not sure how old but prob 8-18 months. is this something i should be concerned about and if so how can I fix it? ill attach a pic if I can catch him doing it again soon, I can also provide a pic of his setup if that's needed. thanks in advance!
