pardon me, but didn't you JUST ask this in different wording?

with that said.
house a snake by size of the snake. plastic housing works fine up until they're too big for it.

Go look at cages like boaphile or animal plastics, they often say the size snake they're suitable for, such as... boaphile has a hatchling rack and such. I have mini boas, they don't take too much space.
