White’s Tree Frog (Ranoidea caerulea) Care Sheet
The White’s Tree Frog is a large, robust and adaptable arboreal amphibian native to Australia and New Guinea. Also widely known as the Australian Green Tree Frog or Dumpy Tree Frog, Ranoidea caerulea is one of the most established tree frog species in captive herpetoculture.
Its relatively calm nature and adaptability have contributed to its popularity, but White’s Tree Frogs still require carefully managed temperature, humidity, ventilation, nutrition and supplementation. Their strong feeding response also means obesity is one of the most important preventable husbandry problems in captivity.

NATURAL HISTORY
Ranoidea caerulea occurs across northern and eastern Australia and parts of New Guinea.
The species occupies a remarkably broad range of environments including:
- Tropical forest
- Woodland
- Wetlands
- River margins
- Seasonally dry habitats
- Agricultural areas
- Gardens
- Areas around human habitation
White’s Tree Frogs are highly adaptable and are frequently found around buildings, water tanks and other artificial structures.
They spend much of their time above ground on:
- Trees
- Branches
- Vegetation
- Rock faces
- Human structures
During daylight they commonly shelter in cool, protected locations before becoming more active after dark.
Their ability to tolerate relatively dry periods distinguishes them from many tropical tree frogs.
ENCLOSURE
White’s Tree Frogs require an arboreal enclosure providing substantial usable vertical space.
For one or two adults, approximately:
60 × 45 × 60 cm (24 × 18 × 24 in)
provides a useful minimum starting point.
Larger accommodation is strongly encouraged, particularly for groups.
The enclosure should provide:
- Numerous climbing opportunities
- Broad resting surfaces
- Multiple hides
- Dense foliage
- Open hunting areas
- Shaded retreats
- Good ventilation
- Easy access to clean water
Height is important, but usable branches and resting locations are more valuable than empty vertical space.
ENCLOSURE TYPE
Front-opening glass terrariums and appropriately constructed arboreal vivariums work particularly well.
The enclosure must be securely closed.
White’s Tree Frogs possess large adhesive toe pads and are capable climbers.
Ventilation should provide good air exchange without excessively drying the enclosure.
Avoid completely sealed environments.
Persistent stagnant humidity can contribute to:
- Bacterial growth
- Fungal growth
- Poor substrate condition
- Skin problems
Humidity and ventilation should therefore be considered together.
SUBSTRATE
Suitable substrates include:
- Organic topsoil
- Coco-based substrate
- Amphibian-safe soil mixtures
- Leaf litter
- Bioactive substrate systems
The substrate should retain some moisture while allowing drainage.
A drainage layer can be useful in planted enclosures.
A covering of leaf litter provides a natural surface while helping protect the underlying substrate.
Avoid:
- Gravel
- Calcium sand
- Fertilised soil
- Chemically treated substrate
- Sharp materials
- Aromatic wood products
Loose substrate should not be allowed to accumulate excessively on feeder insects.
CLIMBING STRUCTURE
White’s Tree Frogs are heavy-bodied arboreal frogs.
Provide substantial branches capable of supporting the weight of an adult.
Useful structures include:
- Cork bark
- Cork tubes
- Natural branches
- Vines
- Bamboo
- Elevated platforms
- Broad-leaved plants
Provide horizontal and diagonal resting surfaces at several heights.
All furnishings must be securely positioned.
PLANTING
Live or artificial plants can provide:
- Visual cover
- Resting locations
- Shade
- Environmental complexity
- Humidity retention
Robust broad-leaved plants are particularly useful.
Plants should be:
- Non-toxic
- Free from pesticides
- Strong enough to support the frogs where appropriate
Dense planting should not eliminate airflow or usable hunting space.
TEMPERATURE
White’s Tree Frogs benefit from a moderate thermal gradient.
Daytime
A useful general ambient range is approximately:
22–26°C (72–79°F)
A warmer upper area can reach approximately:
27–29°C (81–84°F)
provided cooler areas remain freely accessible.
Night
Temperatures may fall naturally overnight.
Approximately:
18–22°C (64–72°F)
is generally suitable.
HEATING
Supplementary heating may not always be necessary where appropriate room temperatures are maintained.
Where heating is required, suitable options can include appropriately installed overhead heating.
Any heating equipment must be controlled by an appropriate thermostat.
Heat sources should create a gradient rather than heating the entire enclosure uniformly.
Avoid heating the enclosure from beneath.
Arboreal frogs naturally move vertically to regulate their environmental exposure.
OVERHEATING
White’s Tree Frogs are robust but should not be exposed to prolonged excessive heat.
Temperatures around or above:
30°C (86°F)
for prolonged periods should be avoided.
The enclosure must never be positioned where direct sunlight can cause uncontrolled heating.
Always provide:
- Cooler areas
- Shade
- Access to water
HUMIDITY
White’s Tree Frogs should not be maintained in permanently saturated conditions.
A useful general humidity range is approximately:
50–70% relative humidity
with temporary increases following misting.
Allow humidity to fluctuate naturally.
The enclosure can become more humid after misting before gradually drying as ventilation removes excess moisture.
This wet-to-drier cycle is preferable to constantly maintaining extremely high humidity.
MISTING
Light misting can provide hydration and temporarily raise humidity.
Misting is often most useful during the evening as the frogs become active.
The enclosure should be allowed to partially dry between misting sessions.
Constantly wet:
- Glass
- Branches
- Substrate
- Frogs
are not the objective.
Good ventilation remains essential.
WATER
A large shallow container of clean amphibian-safe water should always be available.
The water container should allow the frog to:
- Enter easily
- Soak comfortably
- Leave without difficulty
White’s Tree Frogs frequently soak at night and may defecate in their water.
Water should therefore be:
Checked daily and replaced whenever contaminated.
The container should be regularly cleaned.
Use appropriately treated amphibian-safe water.
LIGHTING
Provide a clear day/night cycle.
Approximately:
10–12 hours of daylight
per day is appropriate for routine maintenance.
Good-quality LED lighting can support:
- Natural behavioural rhythms
- Live plant growth
- Normal environmental cues
The enclosure should include shaded locations where frogs can retreat from brighter illumination.
UVB
Low-level UVB is recommended as part of high-quality captive husbandry.
A Ferguson Zone 1-type exposure is appropriate.
Aim for approximately:
UVI 0.5–1.0 in exposed accessible areas
with:
UVI 0 available beneath cover
The frog must always be able to regulate its exposure.
Actual UV exposure depends upon:
- Lamp type
- Reflector
- Distance
- Mesh
- Enclosure height
- Plant cover
- Furnishings
Do not select a UVB lamp solely according to the percentage printed on the packaging.
Where possible, exposure should be confirmed using an appropriate UV Index meter.
DIET
White’s Tree Frogs are opportunistic predators.
Captive diets should be based primarily around varied, appropriately sized invertebrates.
Suitable foods include:
- Crickets
- Locusts
- Cockroaches
- Earthworms
- Appropriate larvae
- Other nutritionally suitable feeder invertebrates
Dietary variety is strongly encouraged.
Reliance upon a single feeder species should be avoided.
Wild-caught insects should generally not be used because of possible:
- Pesticide exposure
- Parasites
- Disease transmission
- Environmental contamination
PREY SIZE
Prey should be appropriately sized for the individual frog.
White’s Tree Frogs possess extremely strong feeding responses and may attempt to consume surprisingly large items.
Their willingness to swallow something does not automatically make it suitable food.
Avoid excessively large prey that could:
- Cause injury
- Be difficult to swallow
- Create digestive problems
Uneaten feeder insects should be removed where necessary.
FEEDING FREQUENCY
Feeding frequency depends upon:
- Age
- Size
- Activity
- Temperature
- Body condition
- Prey size
Juveniles
Growing juveniles can generally be offered appropriately sized prey:
Daily or near-daily
with quantities adjusted according to growth and body condition.
Adults
Healthy adults can generally be fed:
Approximately 2–3 times per week
with quantity adjusted according to body condition.
Feeding after lights-out corresponds well with natural nocturnal activity.
SUPPLEMENTATION
Cultured feeder insects should be appropriately gut-loaded and supplemented.
A suitable supplementation programme should provide:
- Calcium
- Vitamin D3 where appropriate
- Vitamin A
- Other essential vitamins and minerals
Requirements depend upon:
- Frog age
- Diet
- Feeding frequency
- UVB exposure
- Reproductive status
- Supplement formulation
Follow the manufacturer’s recommendations for the particular amphibian-appropriate supplement being used.
VITAMIN A
Vitamin A is important in captive amphibian nutrition.
Deficiency may contribute to abnormalities involving:
- Feeding
- Eyes
- Skin
- Growth
- Reproduction
- Normal epithelial function
A reputable amphibian supplementation programme should provide an appropriate source of vitamin A.
Plain calcium alone does not provide a complete supplementation programme.
BODY CONDITION & OBESITY
Obesity is one of the most important husbandry concerns with captive White’s Tree Frogs.
They are enthusiastic feeders and may continue eating well beyond their nutritional requirements.
Excessive feeding combined with relatively limited captive activity can result in substantial weight gain.
Adult body condition should therefore be monitored carefully.
Pay particular attention to:
- Overall body shape
- Fat deposits
- Mobility
- Activity
- Feeding frequency
Do not use appetite alone to determine how much food should be offered.
A frog begging for food is not necessarily a hungry frog.
SOCIAL HOUSING
White’s Tree Frogs can often be maintained successfully in appropriately sized groups.
Animals housed together should be reasonably similar in size.
The enclosure must provide sufficient:
- Space
- Resting locations
- Hides
- Feeding opportunities
- Climbing structure
Significant size differences should be avoided.
White’s Tree Frogs are opportunistic predators and may attempt to consume considerably smaller frogs.
Group housing also requires monitoring to ensure every animal is feeding normally and maintaining appropriate body condition.
HANDLING
Despite their reputation for being calm and tolerant, White’s Tree Frogs should primarily be considered display animals.
Routine handling is unnecessary.
Amphibian skin is delicate and highly permeable.
When handling is genuinely necessary, clean powder-free nitrile gloves moistened with amphibian-safe water are recommended.
If bare hands must be used, they should be:
- Thoroughly clean
- Free from soap
- Free from sanitiser
- Free from moisturiser
- Free from chemical residues
- Moistened with clean amphibian-safe water
Handling should remain brief and gentle.
BEHAVIOUR
White’s Tree Frogs are primarily nocturnal.
During daylight they commonly remain:
- Inside hides
- Among foliage
- Against enclosure surfaces
- On elevated resting positions
Activity generally increases after dark.
Captive animals often become strongly conditioned to feeding and may approach the enclosure door when they associate movement with food.
This behaviour should not be interpreted as a requirement for physical interaction.
VOCALISATION
Male White’s Tree Frogs can produce surprisingly loud calls.
Calling is particularly common:
- At night
- During humid conditions
- During breeding activity
- In response to environmental sounds
Potential keepers should consider this before positioning the enclosure in a bedroom or other area where nighttime noise may be undesirable.
BREEDING
Breeding is associated with warm, wet seasonal conditions.
Males call to attract females.
Amplexus occurs before females deposit eggs in water.
Captive breeding generally requires deliberate seasonal conditioning and an appropriately designed aquatic breeding environment.
Eggs develop into aquatic tadpoles before metamorphosing into terrestrial froglets.
Successful breeding therefore requires planning for:
- Adult conditioning
- Egg management
- Tadpole accommodation
- Water quality
- Tadpole nutrition
- Metamorphosis
- Large numbers of developing froglets
Breeding should not be attempted without suitable accommodation and long-term plans for resulting offspring.
TADPOLES
Tadpoles are entirely aquatic.
They require:
- Clean water
- Stable water chemistry
- Appropriate temperatures
- Suitable food
- Adequate space
- Good water quality
As metamorphosis approaches, developing froglets must have easy access to suitable surfaces above the water.
Metamorphosing animals should be monitored carefully because their environmental and dietary requirements change rapidly.
ENRICHMENT
White’s Tree Frogs benefit from a structurally complex environment.
Useful enrichment includes:
- Multiple climbing routes
- Different branch diameters
- Elevated hides
- Broad resting surfaces
- Dense foliage
- Open hunting areas
- Leaf cover
- Varied appropriate live prey
The enclosure should allow frogs to choose between:
- High and low positions
- Warmer and cooler areas
- Exposed and sheltered locations
- Different humidity levels
- Different light intensities
Providing environmental choice encourages natural behaviour.
CLEANING & MAINTENANCE
Regular maintenance should include:
- Removing faeces
- Removing uneaten feeder insects
- Replacing contaminated water
- Cleaning the water container
- Removing decaying organic material
- Checking substrate condition
- Inspecting plants
- Checking ventilation
- Inspecting enclosure security
Avoid unnecessarily sterilising a healthy established bioactive enclosure.
Any cleaning products used must be amphibian-safe and thoroughly removed before frogs contact treated surfaces.
BIOSECURITY
Good biosecurity should be maintained between amphibian enclosures.
Equipment should ideally not be shared between unrelated amphibians.
Where equipment must be reused, it should be appropriately cleaned and disinfected.
Hands should be washed before and after enclosure maintenance.
Never release:
- Frogs
- Tadpoles
- Eggs
- Plants
- Substrate
- Enclosure water
- Biological material
into the natural environment.
QUARANTINE
New White’s Tree Frogs should undergo an appropriate quarantine period before entering an established collection.
Monitor:
- Appetite
- Weight
- Body condition
- Activity
- Skin condition
- Faeces
- Hydration
- General behaviour
Separate equipment should ideally be used for quarantined amphibians.
Veterinary assessment and appropriate diagnostic testing should be considered where health concerns exist.
HEALTH
Potential health problems include:
- Obesity
- Bacterial infections
- Fungal infections
- Parasitic disease
- Nutritional deficiencies
- Metabolic bone disease
- Dehydration
- Skin damage
- Trauma
Warning signs include:
- Persistent refusal to feed
- Unexplained weight loss
- Excessive weight gain
- Weakness
- Difficulty climbing
- Abnormal posture
- Skin discolouration
- Redness
- Swelling
- Skin lesions
- Persistent abnormal behaviour
Any persistent or serious health concern should be assessed by a suitably experienced exotic or amphibian veterinarian.
LONG-TERM CONSIDERATIONS
White’s Tree Frogs are frequently described as suitable beginner amphibians.
They are certainly more robust than many delicate frog species, but this should not be confused with being maintenance-free.
Potential keepers should consider:
- Adult enclosure requirements
- Long lifespan
- Heating
- Lighting and UVB
- Supplementation
- Water quality
- Regular maintenance
- Obesity prevention
- Veterinary access
Exceptional captive individuals have reportedly survived for more than 20 years, making acquisition a potentially substantial long-term commitment.
Their calm appearance and tolerance of human presence should also not encourage unnecessary handling.
A spacious, well-structured enclosure allowing natural climbing, resting, hunting and nocturnal activity provides the best opportunity to appreciate this species.
