This is SAD! I've discovered that you only need 1 tank! Maybe two. Yes, I love the birds, the reptiles AND the fish. But all you need is one tank per biotype so choose wisely.
By the Way... How large of a tank would I need to house SA fish, birds and reptiles to live happily ever after. Keep in mind when you give these dimensions that I want the tank to be able to be self-contained where I'd only have to add water from evaporation...
I recommend watching the movie "Bio-Dome" to get an idea of what you'd need for a self-sustaining system. Just ignore every scene with Pauly Shore.
