BeckyG said:A 55 gal would be fine as long as you have lots of hides and stuff in there. The way I judge is that the hatchling shouldn't have to go farther than one half to one body length to find another hide.
If you are going to go with a smaller size, get a 30L rather than a 29 gallon. Snakes are terrestrial and floor space is more important than height. A 29 g will work, but the extra height is not necessary.
