I trust the pet store, since they have never offered to sell me anything. They all own several snakes and/or lizards each. I got the tank, because thats what I have for everything else I own.
Temp is about 93 in the hot end, and humidity is about 60-64%.

They were not positive on the age, just told me about 8 months. I know that girl only has lizards though, so maybe she just didnt know about the snake.
So news paper/paper towel, always, or just for now? Will be a million times easier if I just stick with that.

Ive looked into how to sex it, and yeah. I do NOT want to try myself. I am new to pythons, and I dont want to hurt it, so I will either not worry about the sex, or ill get it to a vet.

I use tanks for everything else, but the tub sounds a lot more sensible, as it would be darker during the day. (its my understanding, that they prefer the dark)

Other than that, if there is anything else I am missing, let me know!!
(BTW the snake has no problems at all with me handling it. I assume it would let me know, otherwise)
