Snake Profile Rainbow Boa

Rainbow Boa Information

The Argentine rainbow boa is recognized as one of the most beautiful snakes in the world. They not only have brilliant orange and red colors, but they also have an abundance of Rainbow iridescences. This appearance is caused by microscopic ridges on their scales that refract light. Rainbow boas have a wide range that includes South America and lower Central America.

Care Requirement

Smaller neonates and juveniles can be temporarily housed in smaller cages, but your adult BRB will need at least a 4′ x 2′ x 2′ habitat. Adult animals will make full use of their enclosure’s floor space and height, so if you have the finances, go even bigger! The requirement for high humidity is one of the most crucial factors of Brazilian Rainbow Boa care.

Screen-topped glass aquariums are unsuitable because the screen lid enables moisture to evaporate too quickly, and glass is a poor heat and humidity insulator. Brazilian Rainbow Boas are a shy species as well. They will most likely perceive you as a predator if you reach in from the top of the enclosure. This species is also well-known for its burrowing habits.

Cork tubes or rounds make excellent naturalistic hides, or you can create your own by drilling a hole in a dark-colored plastic box and filing down any sharp edges. Your Brazilian Rainbow Boa will thrive from at least two hides, one on the cool end of the enclosure and one on the warm end.


When it comes to reptile heating and lighting, the Rainbow Boa prefers a nighttime low of 70 degree Fahrenheit and a daytime high of 80 degree Fahrenheit. A temperature gradient is also advised. This is simple to achieve with heat pads, overhead lights, snake heat lamps, or radiant heat panels.

Brazilian rainbow subspecies are more susceptible to high temperatures and should never be exposed to temperatures above 90 degrees Fahrenheit for an extended period of time (unless being a gravid female). Colombian rainbow boas have a higher tolerance for both higher daytime and lower nighttime temperatures, making this subspecies somewhat simpler to keep than Brazilian rainbow boas.

A thermostat ensures that your cage is never excessively hot or chilly, and it has proven to be an essential tool in creating optimal breeding conditions. Light is the key to making your rainbow boa “shine.” A low wattage fluorescent light installed overhead will give your snake a lovely rainbow display.

Rainbow boas are typically nocturnal, so make sure your ambient lighting are turned off for an 8-12 hour night cycle. Ambient lighting is also essential for any live plants that you may use to decorate your terrarium.

Anery Rainbow Boa


This species is found on the humid jungle floors of Brazil, and they will quickly become exhausted in a low humidity environment. Daily misting should be used to keep the humidity between 75-90 percent for adults and 95-100 percent for neonates without soaking the substrate.

If you’re using an insulated enclosure with a humidity-friendly substrate and still have trouble keeping these levels stable, consider introducing real plants. Not only do living plants help to boost humidity, but they also provide your snake with different textures and fragrances, as well as more spots to hide and feel secure.


Rainbow boa snake bedding should be able to endure moisture without warping or breaking down. High-quality reptile mulch, such as cypress, coconut goods, and aquarium gravel, are among these substrates. Sphagnum and green moss are both excellent ways to visually enhance the appearance of your reptile terrarium while also adding moisture and raising humidity. It is also important to provide some kind of hide for your rainbow boa.



Wild-type Brazilian Rainbow Boas have a rusty brownish-red top and white or cream-colored bellies. Their burgundy backs have irregular black-outlined rings that are occasionally joined, as well as solid black or bulls-eye circles down the sides. Rainbow boas get their name from the magnificent rainbow-like iridescence that their scales reflect in the correct sunlight, especially after shedding.

Unlike Ball Pythons, most Brazilian Rainbow Boa morphs are young, and their genetics are unknown. Some morphs are more over $4,000 in price!

Rainbow Boa


Neonate Brazilian Rainbow Boas are typically aggressive and defensive. Is it possible to blame them? They’re so small that everything is a huge threat to them! Fortunately, because babies’ teeth are so little, they rarely break human skin. Don’t be put off by their initial defensiveness when handling your pet.

In fact, accustoming them to you as a baby reduces their likelihood of biting you as an adult — when their bite actually matters because it hurts! Most Brazilian Rainbow Boas are dormant in their enclosure. During the day, they prefer to remain hidden or burrowed. If you’re a lucky night owl, you might get a glimpse of them exploring their enclosure at night.


Health Treatment

The main illnesses that affect Brazilian Rainbow Boas, like those that affect most snakes, are related to husbandry. Anorexia, blocked sheds, and respiratory illnesses can all be caused by insufficient warmth or humidity. Furthermore, unclean enclosures can cause scale rot and abscesses. Always wipe up waste as soon as you discover it, and consider replacing the entire substrate every 1 to 3 months.
