Brazilian Rainbow Boas are a popular snake for their stunning colors and easy care. Don’t be deceived—although rainbow boas do quite well in captivity, they can be temperamental, especially as small snakes. Once they mature and learn that you aren’t the enemy, they aren’t as aggressive. Here are some things to consider before getting a rainbow boa.

What Size of Tank/Enclosure Does a Brazilian Rainbow Boa Need?

Baby rainbow boas need a 10 to 20-gallon tank. As the snake matures, it will need a larger enclosure. You may eventually want a 6-by-2-by-2-foot tank for your rainbow boa. As these snakes tend to be shy, you should include a cave-style box where they can hide. They do like to crawl, so consider adding climbable branches and vines to your setup.

Do Rainbow Boas Need a Heating Pad?

Rainbow boas naturally live in the Amazon. They are used to higher temperatures and humidity than most homes. Heating pads can help keep them warm throughout the day, as they prefer a daily temperature of 85 to 90 degrees, although adults can tolerate lower temperatures at night. Ideally, you want to provide gradient heat through the tank, from 75 to 90 degrees, so that the snake can regulate its own temperature by moving to warmer or cooler spots.

Do Rainbow Boas Need UVB Light?

Rainbow boas do not need UVB lights. They are nocturnal and do not need nighttime light. Display lighting can make your snake a showpiece during the day. Some rainbow boa owners use red bulbs or basking bulbs to help maintain proper temperatures.

How Much Humidity do Rainbow Boas Need?

In addition to higher temperatures, rainbow boas prefer higher humidity, at least 75%. When they are shedding, you may need to increase the humidity in your home to 90%. A hygrometer can measure the levels so you aren’t guessing. Plants and substrate material can help keep the habitat more humid, but in many areas, you will need to raise the level by misting the environment. In especially dry climates, you may want to use an auto-misting system. They will also need a bowl of water that is replaced often to keep it clean.

What Does a Brazilian Rainbow Boa Eat?

Rainbow boas do well on thawed, frozen mice. Younger snakes eat weekly, but once the snake is an adult, you can offer food about every 10 days. Avoid handling snakes after feeding, because they can regurgitate their food.

Brazilian rainbow boas are beautiful snakes that do well in the right habitat. Once you get that under control, you should have a friend for life, because they can live 25 years or more in captivity.
