I know someone who houses their ball python in those *enormous* christmas tree bins you can find this time of year, and those snakes are completely happy because they've got all sorts of stuff to explore and climb on/over/under. Because of their success, I elected to get a 4ftx2ftx14in tank for my Whiskey girl, though she's only 700 grams right now. As long as I clutter it up enough that she feels secure, she should do fine in that tank. Honestly, if I have the space/money when she gets full grown, I'd love to get her a 6x3 so she can really have room to stretch out and explore.
