Ok, so we all know that UVB decays after x inches and that the dragons need to be within that x inches to gan any benefit from the UVB being emitted from the bulb.
Everyone here pretty much states that most lizard type herps, snakes, and other animals need a cage 2 times larger than the length of the animal. Chinese Water Dragon are climbers not really ground dwellers, so the tank would need less of a footprint and more height to it.
If my future tank is to be 3' to 4' tall (the actual tank part, not including the stand and hood areas), the UVB wont play any benefit towards the lower part of the tank. Is this okay? I mean, is it okay if the entire cage is not drenched in UVB rays? Is it okay that it's truly up to the dragons to get higher up in the cage to bask for heat and UVB?
I plan on building a cage, that happens to be tall and I want to make sure that if the UVB bulb only covers the top half of the tank, that will be alright. Or will I need to add a second bulb halfway down the tank to cover the rest of it?
I have never really seen this question arise and would like to know before starting to fabricate the new enclosure.
