Males actually are the larger growing of the two in captivity in the states. Males exhibit sexual selection for larger size due to competition within males for females selection process, this has evolved larger males, which is common amoung the morelia that exhibit combat.

Size factor is not 9-10 feet, again for the locales that are here in the states, they will only achieve sizes around 6-7 ft on average. VERY large adults can get to be around 8-9, 10 is nearly unheard of in the states, that's a massive snake for the locales we work with.

Good information can be gound on www.inlandreptile.com, and there are caresheets floating around. They are more arboreal as juvenile snakes and become less or more semi-arboreal as they grow older. In fact my older snakes will only perch after eating, and that's about it.

They do well in moderate humidty, increase for sheds. Hot spot around 90 for the basking spot (RHP is what I use), and keep it around 78-80 on the cooler side. Temperatures can drop at night to 75 on the cool side, and 85 on the warm side. They are nippy as hatchlings but calm with size and age. All mine that use to be biters are now the sweetest snakes. Feel free to shoot me a message if you need more, or post in the Morelia section of this forum.
