They are great display animals! Mine rarely use their hides and like to hang out on their ledge or on top of their hides.
I don't have BP's but can say Carpets are curious and active. Mine seem to 'watch' what's going on, they are very aware of their surroundings and like to come out. They aren't nuts active like my son's Corn but they don't just sit there either!
Irian Jayas are the smallest. My male is 6' and my female is not quite 5 1/2', it should be the other way around but no one told them that.
I keep mine in Boaphiles, 4' x 2' x 18". They use every inch of that space.
They are great snakes and I think everyone should have at least two. lol
