Over the next couple of weeks I'm going to be building a terrarium. I have a decorate cast iron
stand that I plan to use. The stand is designed to hold an aquarium that is 12in x 48in. I've
decided that I would like to make it 12in x 48in x 36in to allow my bp to do some climbing. I
would like to use some various tropical plants and a small aquatic area on the "cool" side of
the terrarium.

As I understand things, Python Regius will choose security over thermo-regulation, therefore,
it is not advised to use different styles of hides on the hot and cool side of the enclosure.
Unfortunately, it will be very difficult to construct a semi-aquatic cool hide that is as
accessible as the dry hide. I was considering a type of "bridge" that would allow him to travel
to the other hide but I am worried that he will ignore the cool side in favor of the other. Are
my concerns valid, or am I over thinking this? I would really hate to spend a large amount of
time and money constructing this terrarium if it will be an inadequete enclosure.

Another concern of mine is about mold and bacteria growing on the wooden parts of the enclosure.
My current plan will only have the bottom 12in of the enclosure encased in glass and waterproofed.
The top 24in will be framed in decorate wood and screened in fiberglass screening. Would it be
too difficult to maintain temperature and humidify in such an enclosure, and will the humidity
damage the wood materials?

Lastly, are there any particular plants that I need to steer clear of to protect my BP's health?
I know that several plants are toxic to animals but I haven't heard of any that bother pythons.
As much as I would love to have a tropical semi-aquatic terrarium, the primary purpose is still
to be a home for my BP, so I have to put that first. I'm anxiously awaiting answers. =)
