How big to rainbow boas get? And how big of a tank would you need?

Check out the caresheet .

Caresheet snippets:

Hatchlings approximately 15" - 18"+/-. Females average 5.5', males average 4.5' adult size. Maximum size for this species is around 7 feet in length.

For adult Brazilians an enclosure measuring 48" x 18" x 16" will be sufficient. As rainbow boas are semi-arboreal, a vertically-oriented cage will allow your snake more room to climb & is something to consider if you have the space to accommodate this sort of setup. Remember that ALL enclosures must allow for a proper thermal gradient that the snake can utilize, with a hot spot on one end and a cooler spot on the other.
