My nile is about 20 inches from snout to tail, and right now he's in a 48"x30"x30" enclosure that he had for the good portion of his life. But he's getting big fast and probably not more then a couple months away he'll be needing to move on up. I've got a whole bedroom to play with, so what should I do with it? What should I cover my walls and floor with? how should I start?
