I'm looking at rescuing a ball python for a local reptile rescue and also getting my glass terrarium off Craigslist to save monies.

Since this will be my first snake setup, I'm slowly having to learn what's needed and such.

What I haven't seen mentioned is the size of tank needed. Looks like most ppl suggest a 20g long tank, and then a few think a 10g is fine as well.

The BP I'll be adopting is 2ft long according to the rescuer. She has a second that's 2 and half feet long, but I assume smaller=younger, and I'm wanting a young snake.

Would a 10g work? Or should I stick to finding only a 20g long tank?
