I'm not sure if this should have gone into the boa section or the python section. Sorry if its the wrong area.

I have been thinking about getting an arboreal snake and it has been suggested that I look int GTPs or ATBs. I've done some google searching and each care sheet for each of the 2 species seems a bit different, so I'm here to find some consensus. So tell me if I'm right, and if I'm not, what is the correct answer?

Each species usually gets 4-6 feet, with males being smaller than females. Over 6 feet isn't impossible though.

Each actually needs more of a long cage that simulates trees because they move laterally through the jungle, not so much up and down.

A 20L (30x12x12) would last for 1-3 years but eventually something larger would be needed.

Absolute minimum size enclosure for a full grown would be 24W-18D-18T.

Both can be nippy, but with proper care and handling, this can be minimized. *Not always the case

Readily feed on mice and rats.

Both need base humidity 50%-60%, with humidity up to 85% for shed.
Both need a heat gradiate from mid 70s to mid 80's. No warmer than 90, no colder than 70.

Both won't really use a hide, but still need shrubbery to feel secure.
Both need secure branches of various sizes and thicknesses, but closer to the thickness of the snake the better.

Both need a water dish on the bottom big enough for it soak, but shallow enough for it to easily remove itself.

Both are not Emerald Tree Boa, a species that is larger than either of these.

So where am I wrong? And what is correct? Tell me everything I need to know on how to care for one of these, and which one is generally more forgiving? They both seem to have strict but not impossible requirements, but which one gives the most flexibility?

I have experience - When I was a teen I had 2 corns, a milk, a king, 2 northern water snakes and a ribbon snake. Currently I have 2 corns and a ball python.
