Native Distribution: Aru Islands, Salawati, Misool, Papua, Biak, Supiori, Numfor, Yapen, Papua Guinea (including Normanby) and Australia (Cape York Peninsula, Queensland).
Physical Description: A small 1.5m to 2m tree dwelling python. Basic body color is lime green with a yellow to white belly. Through selective breeding many color variations, ranging from blue to yellow, with varying amounts of green have been developed.

Green Tree Python Habitat

Native Habitat: Warm, humid, tropical rain forests.
Ambient Temperature: 24C to 30C.
Basking Temperature: Needs a basking spot with a temperature between 32C and 36C.
Humidity Range: 60% to 90%.
Lighting: Full spectrum fluorescent.
Terrarium Size: Adults are best kept on their own. Minimum terrarium dimensions: 60cm (length) X 60cm (width) X 120cm (height).
Terrarium Decor: Tropical rain forest motif with several perches or branches for hunting, basking, and sleeping.
Terrarium Substrate: Damp sphagnum moss mixed with fir bark chips.
Terrarium Containment: A top is necessary for containment and to regulate humidity.

Green Tree Python Husbandry

Hygiene: Clean water bowl and spot clean as necessary. Daily misting is beneficial to maintain humidity, however, any condensation on the glass should be allowed to dry out over night.
Feeding: Feed adult snakes several adult mice or one medium rat every 10 to 14 days.
Handling: Handling is tolerated but may be stressful to the snake.
Terrarium Compatibility: Best kept on their own.

Green Tree Python Breeding

Maturity: Sexual maturity is reached around 3 years of age.
Sexing: Probing after young are over 1 year old to avoid fracturing tail vertebrae.
Conditioning: Keep adults well fed on mice and / or rats.
Cycling: Breeding may occur year round after cycling, but usually occurs between December and March. Continue feeding and gradually lower the nighttime low temperatures for the breeders over a period of 6 weeks; e.g. daytime high temperature 30C; nighttime low 21C. See Green Tree Pythons mating photograph.
Sex Ratio: Breed in M/F pairs. Males will fight if put together.
Egg Laying: Gestation is around 100 days. The female will lay between 10 and 30 eggs 15 to 21 days after her pre-egg laying shed.

Green Tree Python Care of Eggs / Young

Incubation Temperature: If given a nesting box, most female Green Tree Pythons will incubate their own eggs by coiling around them in a beehive fashion. If using maternal incubation the ambient temperature should be between 28C and 29C. If using artificial incubation, keep the temperature at 30.5C for the first week, 31.5C for the next five weeks, then 29.5C for the last week.
Incubation / Gestation Time: 7 to 8 weeks. Most breeders pip the eggs after 49 days.
Size at Birth: 10 to 15 grams.
Hatchling Sex Ratio: Not temperature dependant.
Feeding: 1 pinky mouse every 7 to 10 days. Tease feeding is often necessary for young that are reluctant, at first, to feed on pinky mice.
Housing: During their first year, young Green Tree Pythons are best raised individually in small enclosures, e.g. 40cm (length) X 28cm (width) X 15cm (height), with a wet paper towel substrate, a shallow water dish and several perches.

Green Tree Python Ailments

Upper Respiratory Infection: Increase temperature to 32C and administer Cyprofloxacin Hydrochloride at a dosage of 11mg/kg orally every 48 to 72 hours until all symptoms disappear.
Blister Disease: This condition is caused by excessive moisture and poor ventilation. Correcting the problem will usually bring about a cure.
Prolapse: Keep the prolapsed area moist and apply a sugar / water paste to the exposed tissue to cause it to shrink back into place. If this does not happen within 24 hours, see a veterinarian.
