Asian Flying Snake / Golden Tree Snake (Chrysopelea ornata)

Asian Flying Snake / Golden Tree Snake (Chrysopelea ornata) Care Sheet

The Asian Flying Snake, more commonly called the Golden Tree Snake (Chrysopelea ornata), is a highly active arboreal colubrid native to South and Southeast Asia.

It is best known for its extraordinary ability to launch itself from branches, flatten the body and glide through the air between trees. This behaviour has earned members of the genus Chrysopelea the common name “flying snakes”.

Despite their relatively slender build, Golden Tree Snakes are fast, alert, highly arboreal predators that require a large, secure, vertically structured enclosure.

They are also rear-fanged and mildly venomous to prey. Human bites are not generally considered medically serious, but bites should still be avoided and treated appropriately.

This is an intermediate-to-advanced display species rather than a snake suited to frequent handling.

Natural Distribution

Chrysopelea ornata has a broad distribution across South and Southeast Asia.

It occurs in regions including:

  • India
  • Sri Lanka
  • Bangladesh
  • Myanmar
  • Thailand
  • Cambodia
  • Laos
  • Vietnam
  • Malaysia
  • Singapore
  • Indonesia
  • parts of southern China

Its broad range means local populations may experience somewhat different seasonal conditions.

Natural Habitat

Golden Tree Snakes inhabit a range of warm, vegetated environments including:

  • tropical forest
  • forest edges
  • plantations
  • gardens
  • secondary woodland
  • urban vegetation

They are strongly arboreal and spend much of their time above ground.

Captive housing should therefore emphasise height, climbing routes and visual complexity.

Appearance

Colouration varies geographically and individually.

Typical animals show combinations of:

  • green
  • yellow
  • black
  • cream
  • red or orange markings in some populations

The body is long and slender.

Scales often form attractive reticulated or banded patterns.

The head is distinct, with relatively large eyes suited to a visually active daytime predator.

Adult Size

Adults commonly reach approximately:

3–4½ feet

Some individuals may grow larger.

Their slender build means they require considerably more usable space than their body mass might suggest.

Gliding Behaviour

Members of the genus Chrysopelea are among the very few snakes capable of controlled aerial gliding.

When launching, the snake can:

  • leave a branch
  • flatten the body
  • form the body into an aerodynamic shape
  • undulate laterally in the air
  • steer towards another perch

This is true controlled gliding rather than simple falling.

Captive enclosures cannot realistically reproduce long-distance gliding, but they should still provide substantial climbing space and varied elevated routes.

Behaviour

Golden Tree Snakes are highly active.

Typical behaviours include:

  • climbing
  • exploring branches
  • basking
  • watching activity outside the enclosure
  • hunting from elevated positions
  • moving through dense foliage

They are often much more visible during the day than nocturnal arboreal species.

Temperament

Temperament varies.

Some individuals become relatively calm in captivity, while others remain:

  • nervous
  • flighty
  • defensive
  • prone to striking

They can move extremely quickly.

A defensive animal should be given space rather than repeatedly handled.

Venom

Golden Tree Snakes are rear-fanged and possess a venom system used primarily to subdue prey.

Human bites are not generally regarded as medically dangerous in healthy adults, but this should not be interpreted as meaning bites are harmless.

Potential effects can include:

  • local pain
  • swelling
  • irritation
  • redness

Anyone experiencing significant or worsening symptoms should seek medical advice.

Enclosure Size

For an adult, approximately:

48" × 24" × 48"

should be considered a practical minimum.

Larger enclosures are strongly encouraged.

A large enclosure should allow the snake to:

  • climb extensively
  • move horizontally
  • choose different temperatures
  • hide above ground
  • explore multiple levels

Vertical Structure

Height should be genuinely usable.

Provide:

  • horizontal branches
  • diagonal branches
  • vines
  • elevated shelves
  • cork tubes
  • dense foliage

An empty tall vivarium is not adequate.

Branches

Branches should vary in:

  • diameter
  • height
  • angle

They must be securely fixed.

This species is light-bodied but highly active and may launch itself between nearby structures.

Elevated Hides

Provide at least one secure arboreal retreat.

Suitable options include:

  • cork tubes
  • mounted hide boxes
  • dense foliage clusters

Ground-level hides should also be available.

Foliage

Dense vegetation provides:

  • security
  • visual barriers
  • climbing routes
  • shade
  • enrichment

Both live and artificial plants can be used.

Any live plants should be non-toxic and pesticide-free.

Enclosure Security

Security is essential.

Golden Tree Snakes are:

  • slender
  • fast
  • excellent climbers
  • capable of exploiting small gaps

Check carefully around:

  • sliding doors
  • ventilation
  • cable ports
  • roof panels
  • door tracks

Use reliable locks.

Substrate

Suitable substrates include:

  • coco husk
  • coco fibre
  • cypress mulch
  • orchid bark
  • soil-based reptile mixes
  • leaf litter

The substrate should support moderate humidity without remaining permanently wet.

Temperature Gradient

Provide a clear gradient.

Basking area

Approximately:

30–32°C

Warm ambient

Approximately:

26–29°C

Cool area

Approximately:

23–25°C

The snake must always be able to move away from the heat source.

Night Temperatures

Night temperatures can fall moderately to approximately:

21–24°C

Avoid prolonged exposure to excessive cold.

Heating

Overhead heating is most appropriate for an arboreal diurnal snake.

Suitable options include:

  • halogen basking lamps
  • deep heat projectors
  • ceramic heat emitters where necessary

Any internal heat source must be securely guarded.

Thermostat

All heat sources capable of overheating the enclosure should be controlled by a thermostat.

Measure temperatures independently at:

  • basking perch
  • upper warm area
  • middle level
  • lower cool zone

Arboreal snakes may experience very different temperatures at different heights.

Lighting

Golden Tree Snakes are strongly diurnal.

Provide bright daytime lighting and a clear photoperiod.

Approximately:

11–13 hours of daylight

is suitable depending on season.

The enclosure should be genuinely dark at night.

UVB

Low-level UVB is recommended.

Provide a gentle UV gradient so the snake can choose between:

  • direct exposure
  • partial shade
  • complete shade

A UV Index around approximately:

1–2

at accessible basking positions is appropriate where accurately measured.

Humidity

Maintain moderate-to-high humidity.

Approximately:

60–80%

is suitable for much of the time.

Humidity can rise after misting and fall gradually afterwards.

Ventilation

Good ventilation is essential.

Do not create a sealed, constantly wet enclosure in an attempt to maintain humidity.

Poor airflow can contribute to:

  • respiratory problems
  • bacterial growth
  • mould
  • skin disease

Misting

Light misting can help maintain humidity and provide drinking droplets.

Allow some drying between misting cycles.

Daily misting may be suitable in many setups, but actual frequency should depend on measured conditions.

Water

Fresh water must always be available.

Use a stable bowl positioned where the snake can access it easily.

Some individuals may drink droplets from leaves after misting.

Diet in the Wild

Golden Tree Snakes are opportunistic vertebrate predators.

Natural prey includes:

  • lizards
  • geckos
  • frogs
  • birds
  • bats
  • rodents
  • other small vertebrates

Lizards are especially important in the diet of many wild individuals.

Captive Diet

Some established captive animals accept appropriately sized rodents reliably.

Others may initially prefer:

  • lizards
  • scented rodents
  • other naturalistic prey

A detailed feeding history should always be obtained before purchase.

Captive-Bred Animals

Captive-bred animals are strongly preferable.

Advantages include:

  • known feeding history
  • lower parasite risk
  • reduced stress
  • known age
  • better acclimation
  • reduced wild collection pressure

Wild-Caught Animals

Historically, many Golden Tree Snakes in the trade have been wild-caught.

Wild-caught individuals may arrive with:

  • dehydration
  • internal parasites
  • external parasites
  • feeding refusal
  • injuries
  • chronic stress

Strict quarantine is essential.

Prey Size

Use moderate prey sizes.

The meal should create a modest swelling.

This is a naturally slender arboreal snake and should not be deliberately overfed.

Juvenile Feeding

Juveniles can generally be offered appropriately sized prey approximately:

every 5–7 days

depending on:

  • prey size
  • growth
  • body condition

Adult Feeding

Adults can generally be fed approximately:

every 7–14 days

depending on:

  • prey size
  • activity
  • body condition
  • reproductive state

Feeding Tongs

Use long feeding tongs.

Do not hand-feed.

Their speed and rapid feeding response make hand-feeding unnecessary and unsafe.

Handling

Golden Tree Snakes are best regarded as observation animals.

Handling should be:

  • minimal
  • calm
  • purposeful
  • avoided when unnecessary

They are fast enough that a startled animal can leave the keeper’s hands in seconds.

Stress

Reduce stress by providing:

  • dense foliage
  • elevated hides
  • visual barriers
  • predictable routines
  • minimal disturbance

An exposed, frequently handled animal may become chronically defensive.

Social Housing

Individual housing is recommended.

Permanent cohabitation can create:

  • competition
  • feeding accidents
  • reproductive stress
  • difficulty monitoring health

Sexing

Reliable sexing may involve:

  • probing
  • tail morphology
  • veterinary imaging

Probing should only be performed by an experienced person.

Breeding

Golden Tree Snakes are oviparous.

Captive breeding is achievable but remains less common than with mainstream colubrids.

Breeding should only be attempted with mature, healthy animals.

Seasonal Changes

Seasonal variation in:

  • temperature
  • humidity
  • rainfall
  • photoperiod

may influence reproductive activity.

Environmental cycling should remain within safe husbandry limits.

Egg Laying

Females require access to a secure laying area containing appropriately moist substrate.

Suitable media may include:

  • sphagnum moss
  • vermiculite
  • soil-based laying mix

The medium should be humid but not waterlogged.

Clutch Size

Clutch size varies.

Several eggs are typical, with actual number depending upon:

  • female size
  • age
  • body condition

Incubation

Eggs should be incubated under stable warm and humid conditions.

Temperatures around:

26–28°C

are commonly appropriate.

Avoid excessive heat.

Eggs should not be rotated once incubation is established.

Hatchlings

Hatchlings are:

  • small
  • slender
  • fast
  • excellent escape artists

Provide:

  • secure housing
  • fine climbing branches
  • dense foliage
  • appropriately scaled hides
  • clean water
  • correct heat and humidity

Hatchling Feeding

Young Chrysopelea may initially prefer lizard prey.

Some can be established onto scented rodents.

Anyone breeding the species should plan for this before eggs hatch.

Quarantine

All newly acquired snakes should undergo quarantine.

A minimum period of approximately:

90 days

is a sensible starting point.

Longer periods are appropriate for wild-caught animals.

Monitor:

  • body weight
  • feeding
  • faeces
  • respiration
  • skin
  • shedding
  • parasites

Parasites

Wild-caught individuals may carry significant parasite burdens.

Faecal testing is strongly recommended.

Treatment should be based on appropriate veterinary diagnosis.

Signs of Good Health

A healthy Golden Tree Snake should generally show:

  • clear eyes
  • clean nostrils
  • intact scales
  • good muscle tone
  • regular tongue flicking
  • confident climbing
  • alert daytime behaviour
  • regular feeding
  • complete shedding

Warning Signs

Seek veterinary advice for:

  • persistent food refusal accompanied by weight loss
  • repeated regurgitation
  • wheezing
  • open-mouth breathing
  • bubbles around the nostrils
  • skin lesions
  • abnormal swelling
  • persistent retained shed
  • parasites
  • neurological signs
  • severe lethargy

Common Husbandry Mistakes

Insufficient Height

These are highly arboreal snakes.

Empty Tall Enclosures

Height must be filled with usable climbing structure.

Poor Enclosure Security

They are fast and capable escape artists.

Excessive Handling

This species is better suited to observation.

Keeping Them Too Wet

Moderate-to-high humidity should be balanced with airflow.

Poor Lighting

They are strongly diurnal.

Assuming Every Individual Will Eat Rodents

Some animals remain specialised feeders.

Overfeeding

Their naturally slender build should be preserved.

Buying Wild-Caught Animals Without Preparation

Imported animals may require advanced quarantine and feeding strategies.

Responsible Ownership

Before acquiring a Golden Tree Snake, ensure you can provide:

  • large arboreal housing
  • secure containment
  • strong daytime lighting
  • appropriate UVB
  • reliable whole-prey feeding
