sounds like youve gotten some great advise, i would start with that and see how it goes, be sure to get some pics so we can see the setup

heres mine! i started with a 20gal tank and changed to tubs, cheaper, space saving, easier to moniter/maintain temps and humidity and made for much happier snake babys


were no longer using aspen substrate as it kept our humidity too high.. now were using newspaper, im so glad we made the change..so much easier! we also have much smaller water bowl (helped with high humidity, thanks south fla) and ive also put some faux plants.. just for looks

good luck!
