Our breeding pair are currently housed in a 29 gallon terrarium with a screen lid. I am sure you could also use the "arboreal" style racks OR the 66 quart Sterilite racks that Animal Plastics makes... those are about 16" tall or so and would work nicely. We use ours for our corns and kings.
You have to ask specifically for these... they do not appear on AP's website.
