NIce looking Green Tree Python, the more pictures I see of them - the more I want to get one, I have the cash to get a pair but I still am not sure if I really want them yet. .However maybe next season.
Yellow to green in a week? That's crazy! Make sure to take some pics during that period! I haven't seen any of the actually colour change in process. Would be great to see some! May I also ask what you paid?
Cheers
Being able to witness that extreme colour change would be amazing, i would love to see a detailed time line of the change, for an example taking 1 photo of the animal a week when the change starts and until when it finishes and then setting up a slideshow type of thing - would be interesting!
