Green Tree Python

Latin name: Morelia viridis



Sexing and Characteristics:

There are several ways of sexing a snake but the main methods are popping & probing, both of these ways are reliable with probing being the most accurate.

Green Tree Pythons should not be popped due to their delicate spines, if you need your snake sexed, make sure this gets done by a professional.

Green Tree Pythons should not be handled or sexed until a minimum of one year of age as they have very delicate spines which can be easily kinked.

Green Tree Pythons are arboreal & will commonly be found coiled around a branch with their head in the middle of their coil.

There are several localities of Green Tree Pythons available ranging in a variety of colours & size such as Aru, Sorong, Biak etc.

I have personally kept a Merauke locality female due to her intense green colouring, with white flecking & powder blue hues.


Generally Green Tree Pythons reach between 4-6 ft, females are typically larger than males reaching around 6ft.

The size of Green Tree Pythons varies from Locality, with Aru being one of the smaller & more docile species.

Substrate and Water Needs:

For bedding you can use a variety of things, Pine & Cedar are to be avoided as these are toxic to reptiles.

You can use newspaper or paper towel which are cheap but not very appealing.

Orchid Bark, Eco earth, Coco fibre, Cypress mulch or similar are your best bet, they are great at holding humidity & are not too expensive and they look good.

You will need a fair sized water bowl, one the snake can submerse its body in.

Lighting and UVB:

Green Tree Pythons have no special lighting requirements but if you do use a bulb, please ensure the light has a bulb guard to avoid your snake from being burnt.

Temperatures & Humidity:

Your GTP should be provided with a basking spot between 28-30’C (82-86’F) in the hot end.

To achieve these temperatures several heating devices can be used such as:

Ÿ  Heatmats (Not recommended as these snakes mainly stay perched)

Ÿ  Basking/Infrared Bulbs

Ÿ  AHS heaters

Ÿ  Ceramic bulbs

These are down to personal preference & all should be used with the appropriate Thermostats to control the temperature & avoid overheating.

A Green Tree Pythons humidity should be around 70-80% with an increase whilst shedding.

Green Tree Pythons do not need constant high humidity 24 hours a day, they benefit more with a drying out period, spray your snake in the morning ensuring the glass condensates for a few hours.

If help is needed choosing heating/thermostat options, please do not hesitate to contact us & we will guide you in the right direction.


Neonate Green Tree Pythons are best kept in small tubs, with secure perches and foilage as they may go off feeding if they feel insecure.

Juvenile/sub-adult Green Tree Pythons can be housing housed in 60x45x60 Exo-Terra Glass terrarium or similar.

An adult Green Tree Python can be housed in a 3ft x 2ft x 2ft vivarium, if using wood make sure it is water tight and well sealed to prevent warping.

Provide them with appropriate sized perches & plants for hiding, one perch in the hot end & one in the cool end, an appropriately sized water bowl should also be provided.



Description of Diet:

Neonate Green Tree Pythons are able to take pinkies on their first feed.

You should be able to start feeding your snake on pinkies, if they are on the smaller side, then very small pinkies, you may feed them every 7-10 days at this point.

As the snakes grows it will need larger prey items. You will know when they need to go up a size once you can’t see the food item in their belly anymore.

Sub-adults can be fed medium/adult mice every 10-14 days.

Adult snakes should be fed on an appropriately sized meal every 2-3 weeks to avoid becoming overweight.

Green Tree Pythons have slow metabolisms so be careful not to overfeed.

Supplements, Nutrition and Usage:

Generally supplements are not needed but I feel that calcium can benefit breeding females to help the production of eggs, to replace the females calcium levels & prevent them from becoming egg bound.


They are not ideal for beginners as they are not very forgiving if husbandry mistakes are made, so should be left to the more experienced keeper.

I would recommend changing their water every 1-2 days, spot clean every few days, and clean them out properly every 4-6 weeks, using an appropriate disinfectant, I use F10.

Green Tree Pythons are best not handled due to stress & injury although it can be done they do best as a display animal.

Some Words on this Species:

They are very pretty Pythons that make great display snakes & if given the right set-up, make an great eye catching display.

If you have the experience/knowledge they can be very manageable & as with most snakes can have long life spans, so be prepared to take care for an animal for the rest of its life.

I would say they make a lovely display animal but are not the pet to be held but their attractiveness makes up for that.
