The guy on Kingsnake.com seems to know more than most regarding these snakes. I bought two from him a little over a month ago.
He has a phone # and email on kingsnake. His company is DTS Herps and if you go to classifieds, click " other snakes", you'll usually find a couple of listings of his.
The one about "Please take my....." hasn't replied to anyone in months.
If you have any advice for me that would be great. I know mine get pretty low energy if the cage temp falls below 80 F.
If your trying to breed, I'm sure you know they lay eggs.
Snakes of Southeast Asia : Striped Keelback - Xenochrophis vittatus
Above is a site regarding the snakes, but as you said info is hard to come by!
Take Care,
