I recently got a male veiled chameleon. He is housed in a 24x24x48 screen enclosure and I have a terrarium hood with a 12" T5 HO Reptisun 5.0 UVB. Is this UVB setup enough for him? or does he need a longer lamp with a 10.0 UVB?
You’re going to want a 24” fixture for your cage, 12” fixtures honestly aren’t even recommended for the smaller cages because they don’t penetrate as deeply. Get a 10% or 12% bulb for it. You’re cham will be much better off
