Hey there, I've got a pair of '04 Sumatran bloods, and I'm beginning to look to the future and make plans for how I want to house these guys when they get to their mature size.

What size enclosure do those of you who have adult bloods prefer? I'm looking into a number of different options from plastic/PVC caging to tubs, etc. Of course I'd like to house them as economically as possible, but my primary concern is for their health and comfort. Which, of course, is why I want to get an idea of what to shoot for in the long run if funds need to be saved/allocated, etc.

So, if I may pick your brains, what do the people around these parts suggest?
