just curious as to what you keep with other animals. just recently I was told of someone keeping brown tree snakes with black headed pythons. I currently keep together all of my parrots and ground dwelling birds in one aviary, I keep my tree frogs with shinglebacks in a seven foot long unit and all my spiny leaf insects with geckos in a large tank. Fish are just kept with those that are compatible.
From what I have found, a balance in the humidity suit both species. i've kept them together for ages and no problems have arose. as for my birds I have king quail on the ground and budgies, cockatiels and lovebirds together as well.
