Tokay Gecko (Gekko gecko) Care Sheet
The Tokay Gecko is one of the largest, most impressive and instantly recognisable geckos in the world. Famous for its blue-grey colouration, orange or red spotting and remarkably loud call, the species has a reputation for being highly defensive and possessing an exceptionally powerful bite.
Tokay Geckos are intelligent, active and fascinating animals, but they are generally better suited to experienced keepers and should primarily be considered a display species rather than a handling pet.
Captive-bred animals are strongly preferable wherever available.

NATURAL HISTORY
Tokay Geckos have a wide natural distribution across South and Southeast Asia and into parts of East Asia.
They inhabit a variety of environments including:
- Tropical and subtropical forest
- Trees
- Rocky areas and cliffs
- Caves and crevices
- Buildings and other human structures
They are excellent climbers and possess specialised adhesive toe pads that allow them to move across vertical surfaces and even ceilings.
Although primarily arboreal and scansorial, describing them as strictly tree-dwelling oversimplifies their natural behaviour. Wild Tokays also make extensive use of rock faces, crevices and buildings.
They are predominantly nocturnal and typically spend daylight hours concealed within secure retreats.
ENCLOSURE
Tokay Geckos require a tall, spacious enclosure that provides extensive climbing opportunities.
For a single adult, we recommend a minimum enclosure of approximately:
60 × 60 × 90 cm (24 × 24 × 36 in)
Larger accommodation is strongly encouraged, particularly for a large adult male.
An enclosure around:
90 × 60 × 120 cm (36 × 24 × 48 in)
can provide considerably greater scope for climbing, environmental gradients and enrichment.
The enclosure must be:
- Secure
- Escape-proof
- Well ventilated
- Capable of maintaining appropriate humidity
- Extensively furnished
Tokays are powerful, fast and extremely capable climbers. Doors, ventilation panels, cable openings and other potential escape points should be checked carefully.
VERTICAL STRUCTURE
Much of the usable space within a Tokay enclosure should be above ground level.
Provide numerous:
- Cork tubes
- Cork bark
- Thick branches
- Bamboo
- Vines
- Vertical and diagonal climbing structures
- Large-leaved plants
- Elevated resting platforms
Branches and climbing structures should extend through different temperature and lighting zones.
This allows the gecko to regulate its temperature, UV exposure and security without having to descend to the enclosure floor.
All structures must be securely fixed.
HIDES & COVER
Tokays naturally seek tight, secure retreats.
Provide multiple hiding opportunities throughout the enclosure.
Excellent options include:
- Cork tubes
- Cork bark
- Hollow branches
- Dense foliage
- Artificial rock crevices
- Appropriately positioned enclosed hides
At least some retreats should be located high within the enclosure.
Dense visual cover is particularly important for newly acquired or nervous animals.
A Tokay should be able to remain concealed while still having access to suitable temperature zones.
SUBSTRATE
A moisture-retentive naturalistic substrate works well.
Suitable options include mixtures containing:
- Organic soil
- Coco fibre
- Orchid bark
- Leaf litter
- Sphagnum moss in selected areas
A bioactive tropical substrate can also be used.
Springtails and appropriate tropical isopods can form part of a bioactive system.
The substrate should help maintain environmental humidity without remaining permanently saturated or waterlogged.
A drainage layer may be useful in heavily planted or frequently misted enclosures.
Bioactive systems still require routine observation and maintenance.
HEATING
Tokay Geckos require a vertical thermal gradient.
Because they naturally warm themselves from environmental heat and daylight, an appropriate overhead daytime heat source can be provided.
A suitable halogen or incandescent basking lamp can create a warm illuminated area near the upper portion of the enclosure.
Where supplementary or nighttime heating is necessary, an appropriate non-light-emitting source such as a:
- Deep Heat Projector
- Ceramic Heat Emitter
may be used.
All heating equipment capable of overheating the enclosure should be appropriately thermostatically controlled.
Heat sources must be positioned so the gecko cannot contact them and suffer burns.
TEMPERATURE
Provide a gradient rather than attempting to maintain the entire enclosure at one temperature.
Basking/Warm Area
Approximately:
32–35°C (90–95°F)
provides a useful general basking target.
A range of warm perches should be available rather than one tiny concentrated hot spot.
General Daytime Temperature
Approximately:
24–29°C (75–84°F)
through the remainder of the enclosure.
Temperatures should naturally become cooler towards the lower portion.
Night
A nighttime reduction is appropriate.
Approximately:
20–24°C (68–75°F)
is suitable for healthy established animals.
If the room becomes significantly colder, thermostatically controlled non-light-emitting supplementary heat may be necessary.
All visible basking lights should be switched off overnight.
TEMPERATURE MONITORING
Use reliable digital thermometers positioned at different heights within the enclosure.
An infrared temperature gun is useful for checking exposed basking surfaces.
Remember:
A thermostat controls the heater — it does not replace a thermometer.
Because Tokay enclosures are tall, measuring temperature only near the substrate gives an incomplete picture of the environment available to the animal.
UVB & LIGHTING
Although Tokay Geckos are nocturnal, they can still benefit from appropriately controlled UVB exposure.
Wild Tokays may receive low levels of ultraviolet radiation while resting near the entrances of retreats or during periods of exposure around dawn and dusk.
A suitable low-output linear UVB system can therefore be provided.
Aim for approximately:
UVI 1.0–2.0 in the most exposed upper basking area
with extensive opportunities to retreat towards:
UVI 0 in full shade
Dense foliage and hides should allow complete withdrawal from UV exposure.
The correct lamp depends on:
- Lamp type
- Reflector
- Installation distance
- Mesh obstruction
- Enclosure height
- Position of branches and resting sites
Do not select UVB solely according to the percentage printed on the lamp.
A suitable UV meter provides the most reliable way of measuring actual exposure.
PHOTOPERIOD & VISIBLE LIGHT
Provide a clear day/night cycle.
Approximately:
12 hours light / 12 hours darkness
provides a useful general photoperiod, with seasonal variation acceptable.
High-quality LED lighting can also be beneficial in planted enclosures.
All visible and UV lighting should be switched off overnight.
Do not use red, blue or purple night bulbs.
Darkness is an important part of the animal’s normal daily cycle.
HUMIDITY
Tokay Geckos require a humid environment, but the enclosure should not remain permanently saturated.
A useful general range is approximately:
60–80% relative humidity
with natural fluctuations throughout the day.
Humidity can rise considerably following evening misting before gradually declining.
This daily cycle is preferable to attempting to maintain one constant humidity percentage.
The enclosure should provide:
High humidity + good ventilation + periods of surface drying
rather than stagnant, permanently wet conditions.
Monitor humidity using a reliable digital hygrometer.
MISTING & HYDRATION
Misting can be used to:
- Increase humidity
- Provide drinking droplets
- Support live plants
- Reproduce natural moisture cycles
Evening is an appropriate time for the main misting period because Tokays become active after dark.
Additional light misting may be necessary depending on enclosure conditions.
Allow surfaces to partially dry between misting cycles.
Automatic misting systems can be useful in large or planted enclosures but should be adjusted according to actual conditions rather than simply running on a fixed excessive schedule.
WATER
Provide fresh drinking water at all times.
A stable water dish should be positioned where it can be accessed easily.
Some Tokays preferentially lick droplets from leaves, branches and enclosure surfaces following misting, but this does not mean that a water dish should be omitted.
Water should be replaced regularly and the dish cleaned whenever contaminated.
DIET
Tokay Geckos are primarily predatory and consume a wide range of invertebrates.
A varied diet of appropriately sized captive-bred feeder insects is recommended.
Suitable feeders include:
- Crickets
- Locusts
- Dubia roaches
- Other suitable roaches
- Silkworms
- Black soldier fly larvae
- Mealworms
- Other appropriately sized captive-cultured invertebrates
Larger prey should not automatically be considered better.
Choose prey that can be captured and swallowed comfortably.
Dietary variety is preferable to relying exclusively on one feeder species.
VERTEBRATE PREY & PREPARED FRUIT DIETS
Wild Tokays are opportunistic predators and may occasionally consume small vertebrates.
However, rodents are unnecessary as a routine component of the captive diet.
A varied selection of appropriately supplemented invertebrates can provide the basis of a suitable captive diet without regularly offering pinky mice.
Likewise, fruit-based prepared diets formulated for species such as Crested Geckos should not be treated as a normal dietary requirement for Tokay Geckos.
Tokays should primarily be maintained on appropriate animal prey.
FEEDING FREQUENCY
Feeding frequency depends on:
- Age
- Size
- Growth
- Activity
- Reproductive status
- Prey size
- Body condition
Young growing Tokays require food more frequently than established adults.
As a broad guide:
Juveniles: Small meals most days or every other day depending on age and body condition.
Adults: Approximately 2–3 appropriately sized meals each week.
These are guidelines rather than rigid rules.
Monitor the animal’s body condition and adjust feeding accordingly.
CALCIUM & SUPPLEMENTATION
Captive feeder insects should be appropriately supplemented.
A suitable regime should provide:
- Calcium
- Vitamin D3 where appropriate
- Vitamin A
- Other essential vitamins and minerals
There is no universal supplementation schedule appropriate for every product.
Requirements depend on:
- Product formulation
- Age
- Feeding frequency
- Reproductive status
- Diet
- UVB provision
Follow the manufacturer’s recommended dosing schedule for the supplements being used.
Where effective UVB is provided, excessive dietary vitamin D3 supplementation should be avoided.
Feeder insects should also receive an appropriate nutritious diet before being offered.
TEMPERAMENT
Tokay Geckos have a well-earned reputation for defensive behaviour.
When threatened, a Tokay may:
- Vocalise
- Open its mouth
- Lunge
- Bite
- Attempt to flee
- Defend a preferred retreat
Their defensive behaviour should not be interpreted as the animal being “bad” or inherently aggressive.
For a prey animal confronted by a much larger animal, biting can be an effective defensive strategy.
Providing secure retreats and minimising unnecessary disturbance can significantly reduce stress.
HANDLING
Tokay Geckos should generally be regarded as display animals.
Routine handling is unnecessary.
They are:
- Extremely fast
- Strong climbers
- Capable of jumping
- Difficult to restrain safely
- Equipped with a powerful bite
When movement is necessary for enclosure maintenance or veterinary care, it is often safer and less stressful to encourage the animal into a:
- Cork tube
- Hide
- Catch container
- Secure transport box
rather than attempting to grab it.
Heavy gloves are not automatically recommended, as they can significantly reduce dexterity and increase the risk of accidentally injuring the gecko.
Calm container-based transfer is preferable wherever practical.
IF A TOKAY BITES
Tokay Geckos can bite extremely hard and may maintain their grip.
If bitten:
Do not pull or forcibly tear the gecko away.
Doing so can injure both the keeper and the animal.
Remain calm and support the gecko if possible.
Providing the animal with a stable surface and allowing it to release voluntarily is preferable to forcibly removing it.
Once released, clean the wound thoroughly and seek appropriate medical attention if the bite is deep, heavily bleeding or shows signs of infection.
VOCALISATION
Tokays are famous for their remarkably loud calls.
The characteristic:
“To-kay! To-kay!”
call gives the species its common name.
Males can call repeatedly, particularly at night and during reproductive activity.
They can also produce:
- Barks
- Croaks
- Hisses
- Warning vocalisations
Potential keepers should consider this before placing the enclosure in or near a bedroom.
SOCIAL HOUSING
For general captive husbandry, Tokay Geckos are best housed individually.
They are territorial animals and do not require another Tokay for companionship.
Housing multiple animals together can result in:
- Territorial conflict
- Injury
- Competition for food
- Competition for preferred retreats
- Chronic stress
- Breeding pressure
Adult males should not be housed together.
Although experienced breeders may maintain compatible breeding pairs under carefully managed conditions, this should not be treated as the standard housing arrangement for pet Tokays.
Individual housing allows much more accurate monitoring of:
- Feeding
- Faeces
- Weight
- Shedding
- General health
SEXING
Adult males are generally larger and more robust than females.
Mature males also typically show:
- More prominent pre-anal/femoral pores
- Larger post-cloacal structures
- Broader head
- More robust overall build
Females are generally smaller and less heavily built.
Young animals can be more difficult to sex reliably.
SHEDDING
Healthy Tokay Geckos shed their skin periodically and commonly consume the shed.
This is normal behaviour.
Correct hydration and humidity help support successful shedding.
Check for retained skin around:
- Toes
- Tail tip
- Eyes
- Other extremities
Repeated shedding problems may indicate inappropriate humidity, dehydration, nutritional problems or underlying illness.
TAIL LOSS
Tokay Geckos can detach their tail as a defensive mechanism.
The tail will regenerate, but the replacement generally differs in appearance from the original.
Never deliberately cause tail loss and never restrain or lift a Tokay by its tail.
An animal that has recently lost its tail should be monitored carefully for:
- Healing
- Infection
- Feeding
- General condition
Veterinary advice should be sought if the wound appears abnormal.
BREEDING
Tokay Geckos reproduce by laying hard-shelled eggs.
Females generally deposit eggs in protected locations and attach them firmly to a surface.
Suitable sites may include:
- Cork
- Hollow structures
- Vertical surfaces
- Secure crevices
Eggs should not be forcibly removed from a surface once firmly attached, as this can damage them.
Tokays can demonstrate notable parental behaviour, with adults sometimes remaining near and defending eggs.
Breeding should only be undertaken when appropriate facilities are available for adults and offspring.
CLEANING & HYGIENE
Remove:
- Faeces
- Dead feeder insects
- Contaminated substrate
- Decaying food
- Excessive mould
- Dead plant material
as necessary.
Water dishes should be cleaned regularly.
Bioactive enclosures still require routine maintenance.
Because Tokays can become highly defensive when their enclosure is disturbed, cleaning can often be carried out more safely while the animal remains securely concealed within a cork tube or other retreat.
Always wash your hands thoroughly after handling the gecko, feeder insects or enclosure equipment.
Reptiles can carry Salmonella without appearing ill.
HEALTH
Regular observation is particularly important because Tokays may spend considerable time concealed during daylight hours.
Potential warning signs include:
- Persistent loss of appetite
- Unexplained weight loss
- Weakness
- Difficulty climbing
- Swollen or deformed limbs
- Tremors
- Soft or abnormal jaw
- Persistent retained shed
- Skin lesions
- Abnormal faeces
- Regurgitation
- Nasal or oral discharge
- Wheezing
- Open-mouth breathing unrelated to defensive behaviour
- Swelling
- Significant behavioural changes
Metabolic Bone Disease
Inadequate calcium, vitamin D3 and/or UVB provision can contribute to metabolic bone disease.
Signs may include:
- Weakness
- Tremors
- Skeletal deformity
- Difficulty climbing
- Swollen limbs
- Softened jaw
Correct nutrition, supplementation and lighting are fundamental to prevention.
QUARANTINE
New Tokay Geckos should undergo an appropriate quarantine period before introduction to an established reptile collection.
This is particularly important where an animal’s previous history is unknown or where wild-caught origin is suspected.
During quarantine monitor:
- Appetite
- Weight
- Faeces
- Hydration
- Shedding
- External parasites
- General behaviour
Veterinary examination and faecal parasite testing may be appropriate.
Captive-bred animals are strongly preferable where available.
LONG-TERM CONSIDERATIONS
Tokay Geckos can live for many years and require considerably more than a small tropical terrarium.
Before acquiring one, consider:
- Adult enclosure size
- Heating
- UVB
- Lighting
- Electricity
- Live feeder insects
- Supplements
- Veterinary treatment
- Their defensive temperament
- Their powerful bite
- Their loud nighttime vocalisations
They can be spectacular captive reptiles, but someone wanting a gecko primarily for regular handling would generally be better suited to another species.
The Tokay Gecko is at its best when provided with a large, densely furnished enclosure in which its natural climbing, hunting, hiding and vocal behaviour can be observed.
