Hello Miranda, andto BP.net. Good job on doing your research. Having the enclosure up and running beforehand will alleviate alot of anxiety and headaches associated with bringing in a new pet. You mentioned that you were interested in setting up a tub, here is the link to my tutorial on basic, stand alone, tub set-up. I hope it helps.
