Rainbow Brazilian Boa Easy Care Guide

Whenever possible, we advise our clients to acquire a beautiful Rainbow Brazilian Boa. Gorgeous, calm, and requiring minimal effort to maintain, this species is a dream.

If you’re thinking about getting one, though, you should still do your research first.

Many people who are interested in reptiles don’t think about the work involved in caring for one of these snakes. Several complications emerge as a result.

In this manual, we’ll go over everything you need to know to properly care for a Brazilian Rainbow Boa. Interesting information regarding their living conditions, food, personalities, and dimensions will be revealed.

Size of the Rainbow Brazilian Boa

As an adult, a Rainbow Brazilian Boa will typically reach a length of five or six feet. And that’s just one of the many reasons why these snakes are suitable pets for novice pet owners.

These serpents are not miniatures. Nonetheless, they are noticeably smaller than other common species in commerce. That makes these creatures somewhat less dangerous to deal with.

There are, of course, exceptional cases. The average length of a Brazilian Rainbow Boa is about seven feet, but you might see one that’s only four.

If you treat them right, these snakes can live with you for decades. A captive-bred Brazilian Rainbow Boa can expect to live for around 25 years.

Although extremely uncommon, there have been reports of snakes living for up to 50 years (and not all are confirmed).

There is, of course, no way to ensure a long life expectancy. All captive snakes need top-notch care if they are to live as long as the average wild snake. Disease or premature death may result from not meeting their needs.


This species of snake is known as a “Rainbow Boa” for good reason. When compared to other species, their bodies stand out as being noticeably more colorful.

Typically, a maroon or mauve hue is used for the background. It also features crescent-shaped patches. Bright orange fills the pattern, with bold black outlining the design.

This snake certainly stands out due to its striking coloring. It is able to blend in with the fallen leaves, however.

As an alternative, you can choose from a variety of different color morphs. Albino and hypomelanistic snakes are created by many breeders who focus on this niche market. Rare lizards like these can command a hefty price tag.


Even though a Rainbow Brazilian Boa doesn’t require a huge cage, they still need plenty of room to roam. When young, these snakes can thrive in a tank as small as 10 or 20 gallons.

They will need a larger environment once they reach adulthood. The ideal dimensions for such a cage are 48 inches in length, 24 inches in width, and 24 inches in height.

However, there are those who prefer a shorter cage than 36 inches in length. We think this has potential, but a better temperature gradient will be achieved by increasing the size.

Extreme heat and humidity are required for these snakes. Therefore, a glass enclosure is the best option. We can more easily keep the right balance this way. In addition, you can fine-tune the temperature by selecting a top with screening or movable air vents.

Making your space more natural and hygienic is one of the best things you can do for yourself. That’s going to free up a lot of time for other things down the road.

You can choose from a few different substrates. Paper towels can be used for a quick and easy solution. These towels are reasonably priced and perform admirably in their intended function of absorbing and holding moisture.

In contrast, we favor a more organic approach (and we think your Brazilian Rainbow Boa does as well).

In its place, you could use sphagnum moss, cypress mulch, orchid bark, coconut husks, or a sand mixture that snakes like. Humidity is maintained via the absorption of moisture by all of these materials.


When compared to other snakes, Brazilian Rainbow Boas are simple to provide for. It’s best to feed them mice that are roughly their size as a feeder.

Rule of thumb: prey items shouldn’t be much bigger than the snake’s thickest part.

Pinkies are a staple food for juvenile snakes and should be fed to them once a week. Feeding adults once every 10 days is sufficient. Vitamin powder supplements can be dusted onto the mice every few feedings for added insurance.

Frozen mice should be thawed before use. Live mice can be fed to these snakes, but the mice may scratch or bite the snake before they are eaten.
