There was a detailed care sheet posted a couple of years ago (use the search button) for the Asain vine snake. Basically the Ahaetulla nasuta has the same requirements: big cage, humidity over 80%. They eat lizards. I have two of these guys living with a A. prasina in a 5x3x3 foot cagebut the prasina is quite a bit larger than the two nasutas, so you wouldn't need that large a cage for a single nasuta. They are thriving.
