We have our BP in a tank right now (I thought it was 20 gal. but think its only 15) She's about 200g.
rather "petite" for a BP. (she was underfed and we've been working on getting her caught up)

I've heard various comments- like- they dont need much room- just proper hides, water, temps, humidity etc.
(all which have been great in our tank- so far. but im sure if we upgrade size and stay with a tank, it will
be harder to control. But we have 1 BP and its my daughters "pet"- so i can't really imagine putting it
in a tub)

So...How long can she live in this tank size before we need to upgrade?
She still squeezes herself into her small hide from reptile basics. Last feeding she tried to drag her mouse in there with her. Of course that didn't work, and she was wearing the hide on top of her, while trying to eat. LOL She loves that thing- I think
i need to move her up to the next size in that as well- but the next one is so much bigger. not sure she
will like it as much.

Thanks for your opinions!
