I am getting 2 baby WD as pets and am try to design them an indoor habbitat. I bought a book on WD and have read it through and throuh. I have decided to create a 7 foot tall by 3 foot deep by 3 foot wide habbitat, using pvc pipe as a frame and mostly meshing for the sides. I plan on having a water fall originating at 5 foot and casscading into different pools giving them multiple pools to bathe in. The main problems I am having is figuring out what to do about lighting, in a 7 foot habitat.

So question #1
How much lighting does a 7 foot tall habbitat need?

questin #2
I read that a WD needs 300nm of UVB light, what lights do you suggests?

question #3
Last question what kinda of time cycles is recomended for lighting? (Day/Night)

Any Help is appreciated. Thanks.
