Keeping water snakes in semi-aquatic habitats?

[annarawrr]

I think it's been well-established here and on most other snake sites and forums that even with water snakes, their tanks should be kept fairly dry. Just by chance today I found a thread on another forum in which one of the members posted many pictures of his aquarium, half filled with water and live plants, complete with a waterfall of sorts, and two Asian water snakes! This really piqued my interest because incidentally one of the snakes he keeps in the tank is the exact same type of snake I have, enhydris plumbea. Nobody on that thread seemed to have any qualms about this wet and humid snake habitat. I'm not sure if I'm allowed to link the thread here since it's from another forum, but I'd like to know what anyone else thinks about this?

It's really hard to find specific information on my snake, most people just direct me to general water snake care or garter snake info sheets, but here is a guy with the exact same snake but keeping it in a completely different environment than is normally recommended! Does anyone else keep water snakes in semi-aquatic homes?
