At a glance the quick version
Looks how to spot one
Smooth, highly iridescent scales
A medium-sized boa with a glowing orange to reddish-brown body decorated with black rings along the back and dark spots along the sides. In the light its scales shimmer with a rainbow, oil-slick sheen.12
Personality what they are like
Generally fairly docile once used to handling. It is nocturnal and most active in the middle of the night, so it may stay out of sight during the day. Males can be a bit more strong-willed than females.21
Daily activity how busy a day looks
Semi-arboreal and a capable swimmer: spends time on the ground, in branches and in water. A roomy enclosure with climbing branches and a large water bowl suits it.12
Grooming and care the hands-on bits
Once settled, handle for about 10-15 minutes at a time. Keep the substrate moist with a layer of leaf litter to hold humidity.2
Home where they are happiest
Minimum enclosure about 180 x 90 x 90 cm (6 x 3 x 3 ft); larger is better. Basking 30-32 °C, daytime ambient about 26-29 °C, night 22-24 °C. Humidity around 70% by day rising close to 100% at night; juveniles under a year need 90-100%. About 10 cm of tropical soil mix with leaf litter.2
Food basics what goes in the bowl
Whole prey such as mice, rats, hamsters and quail, with variety encouraged. Juveniles eat every 1-2 weeks, adults every 2-4 weeks.2
Company who they like around
Solitary; house individually.2
The story where it all began
Linnaeus described the rainbow boa in 1758, and over time it has been placed in several genera before settling in Epicrates. In the 1980s and early 1990s many were exported from Suriname, but today most pets are captive-bred.1

Five subspecies are recognised, and the Brazilian one is the favourite in the pet hobby.1

Owner questions the things everyone asks
How often should I feed my Brazilian Rainbow Boa?
Juveniles eat every 1 to 2 weeks, while adults eat every 2 to 4 weeks. Furry Diary's starting plan suggests feeding based on species, age and size, so check the food label and ask your vet for exact amounts.2 Furry Diary plan
What does a Brazilian Rainbow Boa eat, and what should it never eat?
It eats whole prey like mice, rats, hamsters and quail, with variety encouraged. What it should never eat is not specified in our sources, so please ask a good breeder or an exotic-pet vet for a safe list.2
How much space does a Brazilian Rainbow Boa need?
A minimum enclosure of about 180 x 90 x 90 cm (6 x 3 x 3 ft) is recommended, and larger is always better. This roomy space suits its semi-arboreal and swimming nature.21
What temperature, light or water does a Brazilian Rainbow Boa need?
Provide a basking spot of 30-32°C, daytime ambient 26-29°C, and night temperature 22-24°C. Humidity should be around 70% by day, rising close to 100% at night; juveniles under a year need 90-100%. A large water bowl for drinking and swimming is essential. Light needs vary, so ask your vet for guidance.21
How often should I clean a Brazilian Rainbow Boa's home?
Spot clean every 2 days to remove waste, and do a full clean every 30 days. Furry Diary's plan includes these steps to keep the habitat fresh. Furry Diary plan
Can a Brazilian Rainbow Boa live with others?
No, it is solitary and should be housed individually to avoid stress or conflict.2
How long does a Brazilian Rainbow Boa live?
With proper care, they can live between 20 and 30 years, so be ready for a long-term companion.21
Can I handle a Brazilian Rainbow Boa?
Yes, once settled it is generally docile and can be handled for about 10 to 15 minutes at a time. Always be gentle and respect its nocturnal nature.2
