Husbandry requirements

Emerald Tree Boa — origin: Northern South America — the Guiana Shield: Guyana, Suriname, French Guiana, Venezuela, northern Brazil and Colombia. Not to be confused with Corallus batesii, the Amazon Basin form..

Terrarium temperature gradient

Night min22 °C
Cool side24–26 °C
Warm side28–30 °C

A canopy snake very sensitive to overheating: do NOT exceed ~31-32 °C. No true hot spot or basking lamp (a nocturnal forest species) — favour gentle ambient warmth and a gradient. The nocturnal drop to 22-24 °C is beneficial.

Enclosure (adult)
90 × 60 × 90 cm

Vertical arboreal terrarium, well ventilated

Height is the priority. Install several horizontal perches (sturdy branches) at different levels and temperatures. A volume of 120x60x120 cm or more is recommended for a large adult. Good ventilation is essential to avoid stagnant air.

Humidity
60–90 %

Cycle the humidity: ~80-90% at night and after misting, letting it fall back to 60-70% during the day. Combine high humidity with good ventilation; stagnant, humid air promotes respiratory infections.

Substrate
Cypress mulchCoconut fibre or barkSphagnum moss

A substrate that retains moisture but drains well. Watch for mould and stagnant humidity; renew regularly.

UVB
Optional

Not essential (nocturnal species). A low-intensity UVB (T5 tube ~5%, Ferguson zone 1) can be beneficial if provided with accessible shaded areas.

Water source
Always available

A large bowl of clean water renewed regularly. The animal drinks mainly the droplets deposited on its body and the branches after spraying; mist regularly to maintain hydration and humidity.

Origin
Boidae

Northern South America — the Guiana Shield: Guyana, Suriname, French Guiana, Venezuela, northern Brazil and Colombia. Not to be confused with Corallus batesii, the Amazon Basin form.

Feeding & health

Diet

Carnivore — Rodents (mice, young rat sized to the snake's girth)

A reactive feeder: feed with tongs, at night, using thawed prey. Moderate, spaced-out meals (slow metabolism) to avoid obesity and regurgitation. Listed under CITES Appendix II (EU Annex B): proof of origin required; favour captive-bred (CBB) individuals, as wild-caught animals are fragile and often parasitised.

Breeding
Viviparous

Gestation of about 6-7 months; sexual maturity around 3-4 years. A slight seasonal cooling stimulates breeding. The newborns (red/orange) require high humidity and are prone to dehydration.

Health watch points
  • Respiratory infections (insufficient ventilation, stagnant humidity, temperatures too low)
  • Regurgitation (handling after a meal, unsuitable temperatures or prey too large)
  • Dehydration and difficult shedding (dysecdysis) when humidity is insufficient
  • Internal parasites, especially in wild-caught animals (nematodes, protozoa)
  • Thermal stress / hyperthermia: overheating can be rapidly fatal

Frequently asked questions

Answers to the most common questions about keeping the emerald tree boa.

How big does an adult Emerald Tree Boa get?
An adult Emerald Tree Boa typically measures 1.5–1.8 m (total adult length. a more slender species, slightly smaller than corallus batesii. ontogenic colour change: red or orange newborns turn green between 6 and 12 months. characteristic large front teeth.).
What temperature and humidity does a Emerald Tree Boa need?
A gradient of roughly 24–26 °C on the cool side to 28–30 °C on the warm side. Humidity 60–90 %.
What does a Emerald Tree Boa eat?
Carnivore: Rodents (mice, young rat sized to the snake's girth).
Is the Emerald Tree Boa a good reptile for beginners?
Advanced level. Defensive, with a reputation as a biter ('nippy'), equipped with very large front teeth. Wild-caught animals are particularly irritable and tricky to acclimatise; captive-bred (CBB) individuals are calmer but remain reactive feeders. Handling should be kept to the strict minimum. Plan ahead: a lifespan of 15–20 yrs.
