Green tree python care guide
Morelia viridis
A fully arboreal display python that perches all day. Perch placement and stable humidity matter more than floor area — an advanced-keeper species.
Arboreal — vertical height first
Green tree python enclosure size
Arboreal — vertical height first. An adult green tree python should live in at least 24" L × 24" W × 30" H; we build toward 36" L × 24" W × 36" H (3 × 2 × 3 ft, roughly 6 sq ft of floor and about a 135-gallon glass equivalent).
- Hatchling / baby
- 18" L × 18" W × 18" H recommended · min 12" L × 12" W × 18" H
- Juvenile
- 24" L × 18" W × 24" H recommended · min 18" L × 18" W × 24" H
- Adult
- 36" L × 24" W × 36" H recommended · min 24" L × 24" W × 30" H
Temperature and heating
Radiant panel above the highest perch on a thermostat; never a hot floor.
- Basking / warm surface
- 86–88°F at the top perch
- Warm side (ambient)
- 82–84°F
- Cool side (ambient)
- 76–78°F
- Night
- 72–75°F
Lighting and UVB
UVB: T5 UVB 5–6% (UVI 1–2 at perch height). Run lights on a 12 hours photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target 60–80%. Daily misting plus a moisture-holding substrate; ventilation must still be good to avoid respiratory infection.
Substrate and depth
Cypress mulch or bioactive soil. Depth: 2–3 in.
Enclosure tips and furnishing
- Two or more horizontal perches at different heights
- Foliage cover around the perches
- Water bowl below
- Smooth perch dowels of correct diameter
Build list
- 24x24x30+ front-opening arboreal cage — Perch height is the usable space.
- Radiant heat panel — Warms a perch from above the way sun through canopy does.
- 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 — stick-on dials are inaccurate.
- Cypress mulch — Holds humidity between mistings.
Green tree python FAQ
How big should an adult Green tree python enclosure be?
At least 24" L × 24" W × 30" H, and we recommend building to 36" L × 24" W × 36" H — about 3 × 2 × 3 ft, or a 135-gallon glass equivalent. Arboreal — vertical height first.
What temperatures does a Green tree python need?
Basking or warm surface 86–88°F at the top perch, warm side 82–84°F, cool side 76–78°F, night 72–75°F. Radiant panel above the highest perch on a thermostat; never a hot floor.
Does a Green tree python need UVB?
T5 UVB 5–6% (UVI 1–2 at perch height). Photoperiod: 12 hours.
What humidity does a Green tree python need?
60–80%. Daily misting plus a moisture-holding substrate; ventilation must still be good to avoid respiratory infection.
What substrate is best for a Green tree python?
Cypress mulch or bioactive soil, at a depth of 2–3 in.
How big does a Green tree python enclosure need to be for a hatchling?
Hatchling / baby: 18" L × 18" W × 18" H recommended, minimum 12" L × 12" W × 18" H. Scale up to the adult footprint as the animal grows.
