Emerald tree boa enclosure size

Arboreal — vertical height first. An adult emerald tree boa should live in at least 24" L × 24" W × 36" H; we build toward 36" L × 24" W × 48" H (3 × 2 × 4 ft, roughly 6 sq ft of floor and about a 180-gallon glass equivalent).

Hatchling / baby
12" L × 12" W × 18" H recommended · min 12" L × 12" W × 12" H
Juvenile
24" L × 18" W × 24" H recommended · min 18" L × 18" W × 24" H
Adult
36" L × 24" W × 48" H recommended · min 24" L × 24" W × 36" H

Temperature and heating

Overhead heat (halogen, deep heat projector or radiant panel) on a thermostat, creating a warm-to-cool gradient.

Basking / warm surface
86–88°F at the top perch
Warm side (ambient)
82–85°F
Cool side (ambient)
75–80°F
Night
No lower than 72°F

Lighting and UVB

UVB: Low-level UVB (ShadeDweller / T5 6%) is beneficial but not strictly required. Run lights on a 12 hours on, 12 hours off photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.

Humidity

Target 60–80%. Nightly misting with good ventilation; never stagnant and wet.

Substrate and depth

Soil/coco or bioactive. Depth: 3–4 in.

Diet and feeding

Frozen-thawed rodents every 2–3 weeks for adults — overfeeding is a common problem.

Enclosure tips and furnishing

  • Horizontal perches at several heights, as wide as the snake's body
  • Dense foliage for cover
  • Water bowl on the floor or elevated

Build list

  • Enclosure at adult size — Buy for the adult footprint to avoid repeated upgrades.
  • Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
  • Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly.
