Amazon ans emerald tree boas are both in the genus Corallus so they are related. Green Tree pythons are in the genus Morelia which includes carpet pythons, scrub pythons, boelen's pythons, all those and more. emerald and amazon tree boas are new world snakes (the americas, canada, everywhere in between) Green Tree pythons are old world snakes (australia, Asia, Europe (and everywhere in between). If you want to get any sort of arboreal I would say start with an amazon, they are more forgiving when it comes to care.Thing about amazons are their attitudes, which are pretty nasty. If you could compare em to colubrids they're like the black racers of the arboreal boids. While there are some calm individuals even those will still try n go for you every now and then. ut if you don't mind the attitude they are a lot of fun to keep. Since they're arboreal have a vertically oriented cage. I put my small one in a ten gal. aqauarium flipped on end with some drift wood and a fake vine in there. for substrate newspaper works, cypress mulch would be good for humidity and looks good. As far as temps go, keep em kinda high I would say 80's-90's. Like all other snakes allow them to have a temp. varience in the cage wit ha hotter end and a cooler end. My amazon spends a lot of time on the ground and most do. Keep them humid but not too humid. I mist mine about 2 or 3 times day whenever I'm in my room checkin up on all my other species. When they get ready to shed (when they turn blue) I soak mine jsut to make sure that it doesnt have any shedding problems, I also mist them more.One thing you don;t want is high humidity and cool temps, these conditiosn lead to respiritory infections that can be fatal and are a hassle. I recommend checking out Mike H.'s site and asking him more about it since he's the go to guy about amazons.
