What are the 6 birds you have? And where did you get a zebra and a fox? lol. I'd have a huge stream with a bunch of ponds/pools, each housing different fish, specifically one with sunfish/shiners/minnows/dace/etc, one with goldfish, one with koi, and one with little to no fish for frogs, salamanders, etc where the fish won't eat them. The 2nd tank would be a huge caribbean biotope, around 2000 gallons, that looks as close to the natural habitat as possible, including details such as sponges, small fish, microfauna, shallow/deep, mangroves, macros, a small beachy area, semi-aquatic crabs/snails, terrestrial/salt-tolerant plants, etc. The 3rd would be a huge paludarium/vivarium/riparium in one, about 16' x 8', I don't know the word for it, but it would have a water section with vertical land, then it comes to and end with the water turning into a stream with flat land, then the 3rd section is a stream and lots of flat land. Amphibians, reptiles, fish, and insects would be in balance. Not to mention it's completely covered with plants/mosses. I love mosses. I'm thinking that a Trinidadian biotope would be cool for this type of setup, possibly Amazonian. The 4th would be an indo-pacific biotope similar to the caribbean one I mentioned. The 5th would be a HUGE reef tank, that is self maintained, that has some rooms (i.e. bedroom, living room, etc.) underneath. This brings a whole new meaning to sleeping with the fishes.:dance:
