Tub for baby Chondro/arboreal snake

I have looking into getting (eventually) an arboreal snake (not sure which type yet), and would like to start it in a tub. I am wondering what size tub I would need, and how do you set one up. I am used to vivariums, and will be doing a vivarium for the arboreal eventually, but not right away. Any help would be appreciated.

I think it depends a lot on what age you are considering. There is a big difference between a Neo & Juvenile.
