Pink-Tongued Skink (Cyclodomorphus gerrardii) Care Sheet
The Pink-Tongued Skink (Cyclodomorphus gerrardii) is a distinctive Australian skink best known for its characteristic pink tongue, elongated body and unusual preference for snails and other soft-bodied invertebrates.
Native to eastern Australia, Pink-Tongued Skinks inhabit relatively humid forest, woodland and vegetated environments. Unlike the more heavily built Blue-Tongued Skinks, they have a slender body, long tail and strong climbing ability.
They are best described as semi-arboreal. Although they spend considerable time on the ground, they readily climb branches, logs and vegetation and should be provided with significantly more vertical structure than a typical terrestrial skink enclosure.
Pink-Tongued Skinks are generally calm animals once established and can become relatively tolerant of careful handling. However, they should still be provided with sufficient cover and opportunities to behave naturally rather than being maintained primarily as handling animals.
One of the most important aspects of their husbandry is diet. Wild Pink-Tongued Skinks specialise heavily in molluscs, particularly snails and slugs. Captive diets should reflect this unusual feeding ecology while still providing appropriate variety and supplementation.
Successful husbandry centres on a spacious, well-structured enclosure, abundant climbing opportunities, appropriate UVB, a moderate basking area, high but fluctuating humidity, fresh water and a varied diet containing suitable molluscs and other nutritious foods.

Natural Distribution
Pink-Tongued Skinks are native to eastern Australia.
Their distribution extends through suitable habitats along parts of the eastern coastal region.
They occur in environments considerably more humid than those occupied by many familiar Australian arid-zone reptiles.
Captive-bred animals should be strongly preferred.
Natural Habitat
Pink-Tongued Skinks inhabit environments including:
- Moist forest
- Woodland
- Forest margins
- Dense vegetation
- Leaf litter
- Fallen timber
- Rocky areas
- Vegetated suburban environments
They frequently utilise areas containing abundant cover and moisture.
Their natural environment should not be interpreted as permanently wet. Good drainage and airflow remain important.
Semi-Arboreal Behaviour
Pink-Tongued Skinks are considerably better climbers than their body shape might initially suggest.
They readily utilise:
- Branches
- Logs
- Cork
- Low vegetation
- Elevated platforms
Captive accommodation should provide genuine three-dimensional usable space.
Appearance
Pink-Tongued Skinks have an elongated body with relatively short limbs and a long tail.
Colouration commonly consists of:
- Grey
- Silver-grey
- Brown
- Olive
- Dark transverse bands
Juveniles are often more strongly patterned than mature adults.
The Pink Tongue
The species takes its common name from its distinctive pink tongue.
This provides an obvious contrast with the blue tongue displayed by Tiliqua species.
The tongue is used as part of the animal’s normal sensory behaviour.
Adult Size
Adults commonly reach approximately:
16–18 inches total length
with a substantial proportion of this length consisting of the tail.
Their slender build means they appear considerably different from the heavier-bodied Blue-Tongued Skinks.
Lifespan
Pink-Tongued Skinks are potentially long-lived reptiles.
With excellent husbandry, a lifespan of:
15–20+ years
may be possible.
They should therefore be considered a long-term commitment.
Behaviour
Pink-Tongued Skinks can be relatively secretive, particularly when newly acquired.
Normal behaviour may include:
- Exploring
- Climbing
- Burrowing beneath cover
- Resting inside cork or foliage
- Hunting for food
- Basking intermittently
- Increased activity during lower-light periods
Adequate cover encourages natural behaviour and often results in a more confident animal.
Activity Pattern
The species is frequently most active during:
- Early morning
- Late afternoon
- Evening
Individual captive animals may also become active during daylight, particularly around feeding or basking periods.
Temperament
Captive-bred Pink-Tongued Skinks are generally regarded as relatively calm.
Once established, many become tolerant of routine keeper activity and careful handling.
Individual temperament always varies.
Handling
Allow newly acquired animals time to settle before beginning unnecessary handling.
When handling:
- Support the entire body
- Allow the animal to move across your hands
- Avoid gripping tightly
- Keep sessions relatively short
- Remain close to the floor or another safe surface
Never lift the animal by its tail.
Enclosure Size
For a single adult:
4 × 2 × 2 ft
should be considered a practical minimum.
Because this species climbs readily, additional height is valuable.
Larger accommodation provides greater opportunity for:
- Climbing
- Exploration
- Thermal gradients
- Dense cover
- Exercise
- Behavioural choice
Enclosure Orientation
Unlike a strictly terrestrial skink, enclosure height should not be wasted.
Provide structures extending through the enclosure rather than keeping all furnishings at floor level.
Climbing Structure
Provide:
- Natural branches
- Cork tubes
- Cork bark
- Logs
- Robust vines
- Elevated platforms
Branches should be securely fixed.
Provide routes that allow the animal to climb without requiring large unsupported jumps.
Hides
Provide several secure hides.
At minimum, include:
- A warm hide
- A cool hide
- A humid retreat
Additional elevated cover is beneficial.
Suitable hides include:
- Cork tubes
- Cork flats
- Hollow logs
- Dense artificial or live vegetation
Visual Cover
Dense cover helps animals feel secure.
Useful cover includes:
- Cork
- Leaf litter
- Branches
- Plants
- Artificial foliage
An enclosure should not be an open box containing only two hides and a water bowl.
Substrate
Suitable substrates include:
- Organic topsoil
- Coco fibre
- Cypress-type mulch
- Leaf litter
- Appropriate tropical soil mixtures
A mixture that retains some moisture while remaining aerated works well.
Substrate Depth
Provide sufficient substrate for natural digging and burrowing behaviour.
Approximately:
3–5 inches
is useful in many setups, with deeper areas where practical.
Bioactive Housing
Pink-Tongued Skinks can do well in appropriately designed bioactive enclosures.
A bioactive system may contain:
- Natural soil
- Leaf litter
- Live plants
- Springtails
- Suitable isopods
Plants should be robust enough to tolerate a relatively large skink moving through them.
Bioactive housing does not remove the need for routine cleaning and health monitoring.
Temperature Gradient
Pink-Tongued Skinks should not be maintained at the very high temperatures associated with many arid Australian lizards.
Provide a moderate thermal gradient.
Basking Temperature
Provide a localised basking surface around:
30–33°C
The animal must be able to move easily into substantially cooler areas.
General Day Temperature
General daytime temperatures can remain around:
22–26°C
Cool Area
Provide cooler areas around:
20–23°C
Night Temperature
Night temperatures can generally fall to approximately:
18–22°C
A natural nighttime reduction is appropriate.
Overheating
Pink-Tongued Skinks can be vulnerable to excessive heat.
Do not allow the entire enclosure to reach basking temperatures.
Particular care is required during warm summer weather.
Always maintain accessible cooler retreats.
Heating
Suitable overhead heating can be used to establish the basking zone.
All heating equipment should be:
- Securely installed
- Appropriately controlled
- Protected from direct contact
- Regularly monitored
Temperature Monitoring
Use reliable digital thermometers to monitor:
- Warm ambient temperature
- Cool-side temperature
An infrared thermometer is useful for checking basking surface temperatures.
UVB
Appropriate UVB should be provided as standard captive husbandry.
UVB supports:
- Vitamin D3 synthesis
- Calcium metabolism
- Healthy skeletal development
- Normal muscular function
- Natural basking behaviour
UV Gradient
The enclosure should provide a gradient from useful UV exposure around the basking area through to complete shade.
The animal should be able to regulate exposure behaviourally.
UVB Placement
Effective UVB provision depends on:
- Lamp output
- Distance
- Mesh obstruction
- Reflector
- Enclosure design
Follow current manufacturer recommendations for the specific UVB equipment being used.
Visible Lighting
Provide a clear day/night cycle with good-quality visible lighting.
Bright daytime lighting supports:
- Natural activity
- Basking behaviour
- Plant growth
- Circadian rhythm
Photoperiod
Approximately:
10–12 hours of daylight
is suitable, with seasonal adjustment possible.
Night Lighting
The enclosure should be dark at night.
Visible red, blue or purple night lamps should not be left operating throughout the night.
Humidity
Pink-Tongued Skinks require more humid conditions than many arid-zone skinks.
General humidity around:
60–80%
is suitable in many setups.
Exact humidity will naturally vary throughout the enclosure and across the day.
Humidity Fluctuation
The enclosure should not remain permanently saturated.
Humidity should rise following misting before gradually falling as surfaces dry.
This produces a healthier environment than constant wetness.
Humid Retreat
Provide a humid hide or retreat containing moisture-retentive material.
This allows the skink to choose higher humidity without requiring the entire enclosure to remain excessively damp.
Misting
Light regular misting may be used to maintain appropriate humidity.
Frequency depends on:
- Ventilation
- Substrate
- Room humidity
- Planting
- Season
Monitor conditions rather than misting according to an inflexible schedule.
Ventilation
Good ventilation is essential.
High humidity combined with stagnant air can contribute to:
- Mould
- Bacterial growth
- Skin problems
- Respiratory disease
The aim is humid, well-ventilated air rather than a constantly wet enclosure.
Water
Provide a clean, stable water bowl large enough for easy drinking.
Fresh water should always be available.
Replace contaminated water promptly.
Diet
Diet is one of the most distinctive aspects of Pink-Tongued Skink husbandry.
In nature, the species feeds heavily on:
- Snails
- Slugs
- Other soft-bodied invertebrates
Captive diets should reflect this mollusc-specialist feeding ecology.
Snails
Snails are an excellent dietary component when obtained from a safe source.
Suitable options may include appropriately sourced:
- Captive-bred feeder snails
- Plain commercially produced edible snails with no added seasoning or sauce
The shell can provide useful calcium.
Wild Snails
Do not automatically collect garden snails or slugs for feeding.
Wild molluscs may carry:
- Parasites
- Pesticides
- Herbicides
- Other environmental contaminants
Only use wild-collected foods where their safety can genuinely be established.
Other Animal Foods
Dietary variety may include suitable quantities of:
- Appropriately sized insects
- Earthworms from safe captive sources
- Other suitable invertebrates
- High-quality formulated foods appropriate for omnivorous skinks
Whole-prey-style foods are preferable to relying heavily on muscle meat.
Insects
Suitable feeder insects include:
- Roaches
- Crickets
- Locusts
- Black soldier fly larvae
- Silkworms
Feeder insects should be appropriately sized and gut-loaded.
Plant Foods
Pink-Tongued Skinks may accept some plant material, although animal foods—particularly molluscs—form an important part of their natural feeding ecology.
Suitable supplementary foods may include small amounts of:
- Leafy greens
- Squash
- Other appropriate vegetables
- Occasional suitable fruit
Fruit should not dominate the diet.
Dietary Variety
Avoid building the diet around a single food item.
A varied feeding programme helps provide a broader nutritional profile and greater behavioural enrichment.
Calcium
Calcium supplementation may be required depending on the composition of the diet.
Whole snails with shell naturally provide calcium, but the entire diet must still be considered.
Insect feeders may require appropriate calcium dusting.
Multivitamins
A suitable reptile multivitamin may be used periodically.
Avoid excessive supplementation.
Feeding Frequency
Juveniles generally require more frequent feeding than adults.
Adults can commonly be offered food approximately:
3 times per week
with quantities adjusted according to:
- Body condition
- Activity
- Age
- Reproductive status
Body Condition
Monitor body condition rather than feeding according to appetite alone.
Adult skinks can become overweight when consistently offered excessive calorie-dense food.
Social Housing
Individual housing is the safest general recommendation.
Although some keepers successfully maintain compatible animals together, social housing introduces additional risks.
Risks of Cohabitation
Potential problems include:
- Food competition
- Basking competition
- Chronic stress
- Aggression
- Unwanted breeding
- Difficulty monitoring individual health
Separate animals immediately if incompatibility develops.
Sexing
Sexing Pink-Tongued Skinks can be difficult, particularly in immature animals.
Mature males may develop:
- Broader heads
- More robust head proportions
- Subtle differences around the tail base
Experienced assessment may be required for reliable sex determination.
Reproduction
Pink-Tongued Skinks are live-bearing.
Females give birth to fully formed young rather than laying eggs.
This distinguishes them from many commonly kept lizards.
Breeding
Only mature animals in excellent health and body condition should be bred.
Successful breeding requires careful attention to:
- Seasonal cycling
- Nutrition
- Calcium
- UVB
- Female condition
- Compatibility
Gestation
Following successful mating, females undergo an extended gestation before giving birth to live young.
Exact duration can vary with environmental conditions and individual animals.
Litter Size
Females may produce approximately:
5–20+ young
with litter size varying substantially according to the size, age and condition of the female.
Newborns
Newborn Pink-Tongued Skinks are relatively well developed but require appropriately scaled accommodation.
Provide:
- Secure housing
- Multiple hides
- Climbing opportunities
- Appropriate UVB
- Moderate basking temperatures
- Suitable humidity
- Fresh water
- Appropriately sized foods
Juvenile Diet
Young skinks should receive a varied, nutrient-rich diet.
Appropriately sized snail material and small invertebrates can be introduced alongside other suitable foods.
Careful calcium provision is particularly important during growth.
Quarantine
All newly acquired reptiles should undergo quarantine.
A minimum of approximately:
90 days
is a sensible starting point.
Monitor:
- Appetite
- Weight
- Faeces
- Skin
- Shedding
- Respiration
- Activity
Veterinary parasite screening may be appropriate, particularly for animals of uncertain origin.
Shedding
Healthy Pink-Tongued Skinks generally shed successfully when humidity and hydration are appropriate.
Retained shed may occur around:
- Toes
- Tail
- Limbs
Provide suitable humidity and textured surfaces.
Do not forcibly remove firmly attached skin.
Signs of Good Health
A healthy Pink-Tongued Skink should generally display:
- Clear eyes
- Alert behaviour
- Strong coordinated movement
- Regular feeding
- Appropriate body condition
- Healthy skin
- Normal shedding
- Normal faeces
- Interest in its surroundings
Warning Signs
Seek veterinary advice for:
- Persistent food refusal
- Unexplained weight loss
- Swelling
- Weakness
- Tremors
- Limb or jaw deformity
- Respiratory symptoms
- Persistent diarrhoea
- Severe retained shed
- Skin lesions
- Significant lethargy
Common Husbandry Mistakes
Treating Them Like a Blue-Tongued Skink
Pink-Tongued Skinks are more slender, more arboreal and generally require greater humidity than typical Tiliqua husbandry provides.
Insufficient Climbing Structure
These skinks readily climb and should be given substantial usable vertical structure.
Excessive Heat
They do not require the extreme temperatures used for many arid-zone Australian lizards.
Poor Humidity Management
Conditions that are too dry can contribute to dehydration and shedding problems.
Constantly Wet Conditions
Higher humidity does not mean permanently saturated substrate.
Poor Ventilation
Humidity must be combined with effective airflow.
No UVB
Appropriate UVB should form part of modern captive husbandry.
Ignoring Their Natural Diet
Snails and other suitable molluscs are an important component of the species’ natural feeding ecology.
Feeding Unsafe Garden Snails
Wild molluscs may carry parasites or environmental contaminants.
Excessive Fruit
Fruit should only form a small supplementary part of the diet.
Overfeeding
Adults can become overweight when fed excessive quantities of calorie-dense foods.
Enclosure Too Open
Provide abundant cover so the animal can retreat and feel secure.
Captive-Bred Animals
Captive-bred Pink-Tongued Skinks should be strongly preferred.
Advantages include:
- Known origin
- Established feeding
- Better adaptation to captivity
- Reduced parasite concerns
- Reduced reliance on wild animals
Captive breeding also allows keepers to establish animals on appropriate diets from an early age.
