Bellatrix has outgrown her current vivarium, which is 22" long. It is no longer big enough to accommodate two hides big enough for her. However, if we upgrade her to a 36" tank, will that be big enough to last her for quite a while or should we go straight to a 45"? The one I'm thinking of getting is this:

Which looks like it could be a good compromise between a tub and something we can still see into, but I don't know if the largest size will still be too small.
