Hello, seeking advice on new python

If that's an Aru, it's a "type 2" phase. Most captive Arus have a more muted pattern. It could be a kinghornii; in which case, prepare for a giant. Then again it could be from a poorly discribed locale.
You're lucky: I've had my Aru about two years now, and he stills strikes for the face. If you haven't had any trouble than you should be alright, but wear some eye protection when handling to be safe.
Mine rarely visits his cage floor, but if you provide perches make sure they're modular. Up the humidity near sheds, and you'll usually get a clean slough. Be carefull not to overfeed if you ever plan to breed, as obesity seems to hinder fertility.
Most importantly, watch the head! Even if she never bites, scrubs are fast and long and slender. Mine's great at getting tangled around chairs and disappearing into couches.

I would also agree with a type 2 Aru...the patterning is similar to a Merauke but it doesn't seem dark enough to be Merauke (although it was my first thought)

This is my freshly shed Merauke and u can see the difference



My biggest scrub is about 10ft and doesn't eat more than a large rat or small squirrel every 2-3 weeks

With a baby it's good to grow them really slowly an have a nice big enclosure so they end up long and lean...I have a 3/4 year old male Merauke and he's still only about 4.5ft long bless him

Humidity doesn't need to be too high...a humid hide is fine

Good luck...he/she is gorgeous!!
