Frequently asked questions
How big do Brazilian rainbow boas get?
4-6 feet as adults. Heavy-bodied. About the size of a ball python with longer proportions.
How long do Brazilian rainbow boas live?
20-25 years with proper husbandry. Some individuals exceed 30.
Are Brazilian rainbow boas good for beginners?
No. Humidity demands are stricter than ball pythons or boas, and they're less forgiving of husbandry mistakes. Better as a second or third snake.
Do Brazilian rainbow boas need high humidity?
Yes — 75-85% sustained. Solid-sided PVC or wood enclosures are essentially required; glass with screen tops cannot hold the humidity.
Are Brazilian rainbow boas defensive?
Juveniles often are. Many adults remain reactive when first handled. With consistent gentle handling many calm; some never fully do.
