i've read through this thread and really the only advice i can give is make sure you can keep your temps and humidity correct at all times. i keep my one and only BP in my bedroom and my bedroom is about 85 degrees or hotter at all times... yikes yes it kinda sucks tryna sleep in the summer with that kind of heat but my snake is healthy and that's all that matters. it doesn't sound like the place you live is very friendly sounding for an animal that comes from africa, but that's just my opinion!

oh yes and i use a tank, and seeing as it's my one and only, i dont' see a problem with it, but if i had oodles of snakes, or had to go to extremes to keep temp/humidity correct, i'd probably go with a tub as well.

good luck
