Amazon Tree Boa (Corallus hortulana) Care Sheet
The Amazon Tree Boa is a slender, highly variable arboreal boa native to tropical South America. Few snakes display such an extraordinary range of natural colouration, with individuals occurring in shades and combinations of brown, grey, yellow, orange, red and black.
Amazon Tree Boas are highly adapted to life above the ground. Their long bodies, muscular prehensile tails and characteristic resting posture allow them to move confidently through branches and vegetation.
They are fascinating display snakes but are generally more defensive than many commonly kept boas. Correct husbandry requires a spacious three-dimensional enclosure, secure climbing structures, appropriate warmth and humidity, good ventilation and an understanding of their strong feeding response.

Natural History
Amazon Tree Boas occur across a large area of tropical South America, including much of the Amazon Basin and surrounding regions.
They inhabit environments including:
- Tropical rainforest
- Forest margins
- Riverine vegetation
- Secondary forest
- Woodland
- Vegetated areas around human disturbance
They spend substantial amounts of time above ground in shrubs, trees and tangled vegetation.
During daylight hours they commonly rest coiled on branches or within dense cover.
At night they become active hunters.
Wild prey can include:
- Small mammals
- Birds
- Lizards
- Frogs
Their arboreal lifestyle must be reflected in captive enclosure design.
Colour & Pattern Variation
Amazon Tree Boas are famous for their remarkable natural variation.
Individuals may display:
- Brown
- Grey
- Yellow
- Orange
- Red
- Black
with patterns ranging from relatively plain animals to heavily marked individuals with saddles, bands, speckling or contrasting patterns.
These colour variations occur naturally and do not necessarily represent conventional selectively bred morphs.
Juvenile colouration can also change considerably as the animal matures.
Enclosure
Amazon Tree Boas require a genuinely three-dimensional enclosure.
For an average adult, approximately:
120 × 60 × 90 cm (48 × 24 × 36 in)
provides a practical minimum starting point, with larger accommodation strongly encouraged.
Particularly large adults benefit from substantially more space.
The enclosure should provide enough room for the snake to:
- Fully stretch
- Climb
- Move horizontally between branches
- Change elevation
- Thermoregulate
- Retreat into dense cover
Height is valuable, but enclosure width and length should not be sacrificed simply to create a tall narrow cage.
Branches & Perches
Correctly positioned branches are fundamental to Amazon Tree Boa husbandry.
Provide branches of several diameters at different:
- Heights
- Angles
- Temperatures
- Levels of cover
Horizontal and gently angled branches are particularly useful resting locations.
Branches must be extremely secure.
A branch that shifts or collapses beneath the snake can cause injury and make the animal reluctant to use elevated areas.
Natural branches, cork and other reptile-safe structures can be used.
Enclosure Security
Amazon Tree Boas are slender, strong and excellent climbers.
The enclosure must be completely secure.
Check:
- Doors
- Locks
- Ventilation
- Cable openings
- Sliding-door gaps
- Background edges
- Lamp fittings
Any internally mounted heating or lighting equipment must be protected with secure guards.
The snake must never be able to coil directly around an unguarded heat source.
Housing
Amazon Tree Boas should normally be housed individually.
Permanent cohabitation provides no essential social benefit and introduces risks including:
- Feeding accidents
- Competition for preferred perches
- Competition for thermal resources
- Stress
- Unwanted breeding
- Difficulty monitoring individual health
Animals intended for breeding should only be introduced deliberately and monitored appropriately.
Temperature & Heating
Provide a thermal gradient throughout the enclosure.
Suitable temperatures are approximately:
Basking area: 30–32°C
Warm ambient area: approximately 27–29°C
Cooler area: approximately 23–25°C
Night: approximately 21–24°C
Avoid maintaining the entire enclosure at the basking temperature.
Because Amazon Tree Boas spend much of their time elevated, temperature should be measured at the actual perching locations, not only at floor level.
Overhead heating is generally recommended.
Suitable heat sources can include:
- Halogen basking lamps
- Deep heat projectors
- Ceramic heat emitters where appropriate
All heat sources must be controlled by a suitable thermostat.
Internally mounted heaters must be protected by secure guards.
Lighting & UVB
Provide approximately:
10–12 hours of light per day
with seasonal adjustment if desired.
Although Amazon Tree Boas have historically been maintained without UVB, providing access to low-level UVB is recommended where practical.
Aim for approximately:
UVI 1–2 at suitable exposed perches
while providing dense shaded areas where UV exposure approaches zero.
The snake should be able to choose its level of exposure.
A linear UVB lamp is generally preferable for creating a useful gradient.
Actual UV exposure depends upon:
- Lamp output
- Reflector
- Mesh
- Distance
- Branch position
- Vegetation
Follow manufacturer recommendations and ideally verify exposure using an appropriate UV meter.
The enclosure should become dark at night.
Avoid coloured nighttime bulbs.
Humidity
Amazon Tree Boas require moderate to relatively high humidity combined with good ventilation.
A useful general range is approximately:
60–80% relative humidity
with natural daily fluctuations.
Humidity can rise following misting and then gradually decline.
The enclosure should not remain constantly saturated.
Persistent stagnant moisture can contribute to:
- Skin infections
- Respiratory problems
- Bacterial growth
- Fungal growth
High humidity and good airflow are not contradictory. Both should be incorporated into enclosure design.
Misting
Periodic misting can help maintain humidity and provide environmental variation.
Misting is particularly useful around the evening when the snake naturally becomes more active.
Allow surfaces to partially dry between misting cycles.
Automated misting systems can be useful in larger planted enclosures but must be adjusted appropriately.
Constantly spraying the enclosure throughout the day is unnecessary and may create poor conditions.
Water
Fresh drinking water must be available at all times.
Provide a stable water bowl large enough for comfortable drinking.
Some individuals may prefer drinking from droplets following misting, but this should not replace access to a water bowl.
Water should be changed regularly and immediately whenever contaminated.
Persistent soaking can occasionally indicate:
- Mites
- Excessive temperatures
- Dehydration
- Other husbandry problems
and should be investigated when unusual for the individual.
Substrate
Suitable substrates include:
- Reptile-safe soil mixtures
- Coconut husk
- Coconut fibre
- Orchid bark
- Cypress-type mulch
- Naturalistic tropical substrate mixtures
Leaf litter can provide additional ground cover and enrichment.
Good drainage is particularly important in humid enclosures.
Avoid:
- Cedar
- Pine
- Calcium sand
- Sharp gravel
- Artificially scented substrates
Paper-based substrate can be useful during quarantine.
Furnishing & Enrichment
Amazon Tree Boas should be provided with a complex arboreal environment.
Suitable enrichment includes:
- Branches of different diameters
- Cork tubes
- Dense artificial or live foliage
- Elevated hides
- Visual barriers
- Different perch heights
- Leaf litter
- Textured surfaces
Foliage around resting branches provides valuable security.
The snake should be able to travel through significant portions of the enclosure without being completely exposed.
Arboreal Hides
Traditional floor-level hides alone are insufficient for an arboreal snake.
Provide elevated security using:
- Cork tubes
- Dense foliage
- Elevated hide boxes
- Covered branch junctions
Floor hides can still be provided, but the snake should not need to descend to ground level simply to feel secure.
Multiple elevated retreats allow the animal to choose both security and temperature.
Diet
Amazon Tree Boas are carnivorous.
Captive animals can generally be maintained primarily on appropriately sized rodents.
Suitable prey includes:
- Mice
- Rats of suitable size
- Other appropriately sourced whole vertebrate prey where appropriate
Frozen-thawed prey is generally recommended.
Prey should be selected according to the snake’s body condition and girth.
Amazon Tree Boas are relatively slender snakes and do not require excessively large meals.
Feeding Frequency
Juveniles require smaller meals more frequently while growing.
Healthy adults can generally be offered an appropriately sized meal approximately every:
10–14 days
with larger meals offered less frequently.
Feeding frequency should be adjusted according to:
- Prey size
- Body condition
- Age
- Activity
- Reproductive status
Avoid power-feeding juveniles in an attempt to maximise growth.
Slow, steady development is preferable.
Feeding Response
Amazon Tree Boas frequently possess a very strong feeding response.
They may launch rapidly from a perch when prey is presented.
Use long feeding tongs.
Keep hands away from the strike zone when the snake is in feeding mode.
Avoid introducing hands carrying rodent scent into the enclosure.
A consistent maintenance routine can help distinguish feeding from routine interaction.
There is generally no need to move the snake to another enclosure for feeding.
Defensive Behaviour
Amazon Tree Boas have a reputation for being defensive, particularly when young or newly acquired.
A threatened snake may:
- Assume an S-shaped strike position
- Track movement closely
- Strike repeatedly
- Attempt to retreat
Their long neck and arboreal posture can give them an unexpectedly large striking range.
Defensive behaviour should not be interpreted as a character defect.
It is a natural response to perceived threats.
Providing sufficient cover and minimising unnecessary disturbance can greatly reduce defensive behaviour.
Handling
Some captive-bred Amazon Tree Boas become relatively tolerant of handling, while others remain defensive throughout life.
They should primarily be regarded as display-oriented snakes.
When handling is necessary:
- Approach calmly
- Avoid approaching directly towards the head
- Support the body
- Allow the tail to release branches naturally
- Never forcibly pull a snake from a perch
- Keep sessions appropriate to the individual
A snake hook can be useful for initiating handling with defensive adults.
Avoid handling immediately after feeding or during shedding.
Prehensile Tail
Amazon Tree Boas possess a strongly prehensile tail.
The tail is used to anchor the snake securely while climbing and hunting.
When removing an animal from a branch, never pull the snake while the tail remains tightly wrapped around the perch.
Allow it to release voluntarily or carefully encourage the coils to loosen.
Forcing the tail away can cause injury.
Shedding
Before shedding, the snake may:
- Become duller
- Develop cloudy eyes
- Spend more time hidden
- Reduce activity
- Refuse food
Healthy Amazon Tree Boas should normally shed in one complete piece.
Provide:
- Fresh water
- Correct humidity
- Good hydration
- Textured branches and cork
Repeated incomplete sheds may indicate dehydration, inappropriate humidity or illness.
Retained spectacles and stubborn retained skin should not be forcibly removed from a dry snake.
Health
Potential health concerns include:
- Respiratory infections
- Mites
- Internal parasites
- Retained shed
- Skin infections
- Mouth infections
- Dehydration
- Obesity
- Regurgitation
- Burns
- Reproductive complications
Warning signs include:
- Persistent weight loss
- Repeated regurgitation
- Wheezing
- Open-mouth breathing
- Excessive mucus
- Bubbles around the mouth or nostrils
- Abnormal swelling
- Persistent abnormal faeces
- Neurological abnormalities
- Significant behavioural changes
Persistent or serious symptoms require assessment by a suitably experienced reptile/exotic veterinarian.
Respiratory Health
Arboreal tropical snakes are sometimes kept in enclosures that are excessively wet with poor ventilation.
This combination can contribute to respiratory disease.
Signs can include:
- Wheezing
- Clicking sounds
- Excess mucus
- Open-mouth breathing
- Bubbles around the nostrils
- Holding the head in unusual positions
High humidity should therefore never be achieved by eliminating ventilation.
Correct temperature, hydration, humidity and airflow must work together.
Quarantine
New snakes should undergo quarantine away from established reptiles.
During quarantine:
- Record body weight
- Monitor feeding
- Check carefully for mites
- Observe faeces
- Monitor breathing
- Use easily cleaned furnishings
- Maintain separate equipment where practical
Veterinary faecal testing may be particularly appropriate for animals of uncertain or wild-caught origin.
Captive-bred animals should be strongly preferred.
Breeding
Amazon Tree Boas are live-bearing.
Females give birth to fully formed live young rather than laying eggs.
Only healthy, mature animals in suitable body condition should be bred.
Breeding requires an understanding of:
- Sexing
- Sexual maturity
- Seasonal cycling
- Pairing
- Courtship
- Ovulation
- Gestation
- Female body condition
- Neonatal husbandry
Females can produce multiple offspring and reproduction places considerable demands upon their reserves.
Males and females do not need to remain housed together permanently.
Neonates
Newborn Amazon Tree Boas are slender, arboreal snakes requiring extremely secure accommodation.
Provide:
- Small secure perches
- Appropriate thermal gradient
- Elevated cover
- Fresh water
- Correct humidity
- Suitable prey
Neonates can be defensive and extremely quick.
Some may initially require additional patience when establishing feeding.
Body weight and condition should be monitored carefully.
Responsible Ownership
Amazon Tree Boas are frequently chosen because of their extraordinary colours, but prospective keepers should also consider their behaviour and husbandry requirements.
Before acquiring one, ensure you can provide:
- A large arboreal enclosure
- Secure climbing structures
- Appropriate environmental control
- Long-term veterinary care
- Safe management of a defensive snake
- A commitment potentially exceeding 20 years
Captive-bred animals should be strongly preferred over wild-caught specimens.
Never release a captive snake into the wild.
Summary
The Amazon Tree Boa is one of the most visually variable and fascinating arboreal boas maintained in captivity.
Successful husbandry requires a spacious three-dimensional enclosure, numerous secure branches and elevated retreats, carefully controlled warmth, moderate-to-high humidity combined with excellent ventilation, low-level UVB and appropriately sized whole prey.
Their strong feeding response and frequently defensive temperament make them more appropriate for intermediate or experienced keepers than someone seeking a routinely handled snake.
When their arboreal behaviour is properly accommodated, Corallus hortulana makes an exceptional display species.
