Why Choose a Borneo Eared Tree Frog?

Distinctive Ear-like Head Ridges

The Borneo Eared Tree Frog is instantly recognisable by the raised, serrated bony ridges behind its eyes. These structures resemble ears and give the species its common name.

This unusual head shape distinguishes it from many other tree frogs and makes it an appealing choice for amphibian enthusiasts interested in unusual natural adaptations.

Attractive Striped Colouration

Its body typically displays a cream, yellow, tan or light-brown base colour, complemented by dark longitudinal stripes and additional markings across the limbs.

These patterns help the frog blend into bark, branches and other natural surfaces. Individual colouration can vary, so enquire about the actual specimen if appearance is important to your purchase.

Impressive Climbing and Jumping Abilities

As an arboreal species, the Borneo Eared Tree Frog is adapted to life above the ground. Its strong limbs and expanded toe pads help it climb branches, grip foliage and jump between suitable surfaces.

A vertically oriented enclosure with sturdy branches and broad leaves provides opportunities for natural movement and exploration.

Fascinating Night-time Activity

Borneo Eared Tree Frogs are generally most active after dark. During the day, they may rest on branches or remain concealed among foliage.

Their evening activity can include climbing, searching for food and calling, particularly under suitable breeding conditions. This behaviour makes them rewarding to observe without frequent handling.

A Larger Tree Frog for a Carefully Planned Terrarium

With adults often reaching around 7–10 cm in body length, this species offers a more substantial presence than many small tree frogs.

Its size and activity make adequate enclosure space important. A carefully planned habitat should include vertical climbing opportunities, secure resting areas and suitable environmental conditions.

Physical Appearance and Identification

Prominent Cranial Ridges

The species’ most distinctive feature is the raised, serrated ridge above and behind each eardrum. These bony extensions create the characteristic file-like appearance.

Body Colour

The body may range from cream and yellow to tan or light brown. Colouration and pattern intensity vary between individuals.

Dark Stripes and Leg Markings

Longitudinal dark stripes commonly run along the back and sides, while the legs display contrasting bands or smaller markings.

Large Eyes and Toe Pads

The frog has prominent eyes and expanded toe pads that support its arboreal lifestyle.

Differences Between Males and Females

Females generally grow larger and have a more robust body than males. Males may be slimmer and are known for their calling behaviour during the breeding season.

Sexing young frogs can be difficult. If you require a particular sex, ask the supplier whether it can be identified reliably rather than assuming it can be guaranteed.

Size and Growth

Adult Borneo Eared Tree Frogs typically reach approximately 7–10 cm in body length, although measurements vary and some individuals may be larger. Females are usually more robust than males.

Young frogs require appropriately sized live prey and a secure enclosure with no gaps through which they could escape. As they grow, their feeding routine and available space should be adjusted to suit their size.

Before purchasing, enquire about the frog’s current measurements, developmental stage and feeding history. These details will help you choose suitable feeder insects and prepare an appropriate habitat.

Because this species can become a relatively large tree frog, plan for its adult size rather than selecting an enclosure based only on the dimensions of a juvenile.

Natural Habitat and Behaviour

Native to Borneo

The Borneo Eared Tree Frog is native to Borneo, an island shared by Brunei, Indonesia and Malaysia.

It occurs in forest environments and suitable modified habitats, particularly where vegetation and breeding water bodies are available.

Arboreal Lifestyle

This species spends much of its time above ground, perching on branches and vegetation. Its climbing abilities allow it to use different levels of its environment.

In captivity, a vertical terrarium with sturdy branches, cork bark and broad-leaved plants can provide suitable climbing and resting opportunities.

Nocturnal Activity

The frog is generally more active during the evening and night. It may rest quietly during the day before becoming more active when light levels decrease.

A consistent light-dark cycle and sheltered daytime resting areas help support its normal activity pattern.

Calling Behaviour

Males can produce loud calls, especially during the breeding season or under suitable environmental conditions. This is an important consideration when deciding where to place the enclosure in your home.

Breeding Behaviour

Like other members of its group, the Borneo Eared Tree Frog can produce foam nests attached to vegetation above water. The developing tadpoles subsequently enter the water below.

Breeding requires additional planning, suitable conditions and appropriate care for eggs and tadpoles. It should not be attempted without researching the species’ specific reproductive requirements.

Borneo Eared Tree Frog Enclosure Setup

A suitable enclosure should provide ample vertical space, sturdy climbing structures, sheltered resting places, good ventilation and stable environmental conditions.

Enclosure Size

For one adult, a vertically oriented terrarium measuring approximately 45 × 45 × 60 cm can serve as a preliminary planning reference. A larger enclosure may be preferable for an active adult or a group.

The final dimensions should reflect the frog’s adult size, available climbing space and enclosure design. Any group housing requires additional room and careful monitoring.

Choose a secure terrarium with a properly fitted lid to prevent escapes.

Climbing Branches

Provide sturdy branches, cork bark and suitable climbing structures at different heights.

Arrange the furnishings to create natural routes between resting places. Ensure that branches cannot fall or shift when the frog jumps or climbs.

Plants and Foliage

Live or artificial plants can provide cover and resting surfaces. Broad leaves and sturdy stems help create a naturalistic environment.

If using live plants, select varieties suitable for amphibian enclosures and ensure they have not been treated with pesticides or other harmful chemicals.

Hiding and Resting Places

Provide sheltered locations among foliage, branches and cork structures. These areas allow the frog to rest during daylight hours and retreat when disturbed.

Avoid overcrowding the enclosure with decorations that restrict movement or create unsafe gaps.

Substrate

A suitable substrate can help retain moisture and support live plants. Depending on the enclosure design, appropriate options may include coconut fibre, suitable soil mixes and leaf litter.

Prevent waterlogging and remove waste regularly. Avoid loose materials that could be swallowed accidentally during feeding.

Water Dish

Provide a shallow dish containing clean, dechlorinated water. It should be easy for the frog to enter and leave safely.

Replace the water regularly and clean the dish to prevent waste and contaminants from accumulating.

Ventilation

Humidity is important, but stagnant air can encourage mould and other problems. Ensure that the enclosure has appropriate ventilation and monitor temperature and humidity with reliable instruments.

The goal is to maintain suitable moisture without keeping the habitat permanently saturated.

Temperature Requirements

Temperature control is important for maintaining the health of Borneo Eared Tree Frogs. Published husbandry recommendations vary, so the exact range should be confirmed for the identified species.

A temperature of approximately 22–26°C is a cautious starting reference while you confirm the recommended conditions for your animal. Some care guides recommend cooler ambient conditions than those used for other tropical tree frogs.

Important precautions include:

• Use reliable thermometers to monitor enclosure conditions.
• Avoid prolonged excessive heat.
• Prevent sudden temperature fluctuations.
• Use thermostatically controlled heating equipment when required.
• Ensure that the frog can move away from warmer areas.
• Confirm the appropriate daytime and night-time ranges before purchasing.

Do not assume that every tropical frog requires high temperatures. Excessive heat can be dangerous, and species-specific husbandry guidance should take priority over generic recommendations.

Humidity Requirements

Borneo Eared Tree Frogs require appropriate moisture levels, balanced with good airflow.

A relative humidity range of approximately 60–80% is a general starting reference. The appropriate range can vary with temperature, enclosure design and the animal’s condition.

To maintain suitable humidity:

• Use a reliable hygrometer.
• Mist with clean, dechlorinated water as needed.
• Provide a suitable moisture-retaining substrate.
• Maintain access to clean water.
• Ensure adequate ventilation.
• Remove waste and monitor for mould.
• Avoid leaving the enclosure continuously saturated.

Monitor humidity throughout the day instead of relying on a single reading. The goal is a stable, clean environment that supports the frog without creating persistently wet or stagnant conditions.

Lighting and Day-Night Cycle

A consistent light-dark cycle helps support the frog’s daily routine.

Approximately 10–12 hours of light followed by darkness is a useful starting reference. Low-level UVB lighting may be beneficial when appropriately selected and installed, but its use and intensity should be confirmed for the species and enclosure.

Provide shaded resting places so the frog can avoid direct illumination. Lighting should not create excessive heat or dry the habitat too quickly.

If the terrarium contains live plants, choose lighting that supports plant growth while maintaining appropriate conditions for the frog.

What Do Borneo Eared Tree Frogs Eat?

Borneo Eared Tree Frogs are carnivorous and require appropriately sized live prey.

A varied diet can include suitable feeder insects obtained from reliable sources.

Crickets

Appropriately sized crickets are a common feeder insect and can form part of a varied diet.

Small Cockroaches

Suitable feeder cockroaches can provide dietary variety when they are an appropriate size for the frog.

Other Feeder Insects

Depending on the frog’s size, other suitable insects may be offered to provide variety. Avoid wild-caught prey that may have been exposed to pesticides or other harmful chemicals.

Feeding Frequency

Juveniles generally require more frequent feeding than adults. Feeding frequency should be adjusted according to age, prey size, body condition, appetite and the animal’s growth.

Observe the frog during feeding and remove uneaten prey when necessary.

Gut-Loading and Supplements

Feeder insects should be appropriately nourished before being offered. Calcium and vitamin supplementation may be required to support a balanced diet.

Follow a species-appropriate supplementation routine and avoid excessive supplementation. An amphibian-experienced veterinarian can provide advice if you are uncertain about the correct approach.

Lifespan and Long-term Care

A lifespan of approximately 5–10 years is a broad estimate for Borneo Eared Tree Frogs, although individual longevity varies with genetics, health and husbandry.

Long-term care includes:

• Maintaining appropriate temperatures and humidity.
• Providing a secure enclosure with climbing structures.
• Offering suitable live prey.
• Keeping water clean.
• Maintaining enclosure hygiene.
• Minimising unnecessary handling.
• Monitoring appetite, activity and body condition.
• Seeking veterinary care when health concerns arise.

Prepare the enclosure and feeding arrangements before purchasing. Consistent husbandry helps reduce stress during the transition into captivity.

Can Borneo Eared Tree Frogs Live Together?

Borneo Eared Tree Frogs may be kept in groups when sufficient space and suitable conditions are provided, but group housing requires careful planning.

Compatibility depends on individual size, sex, behaviour, enclosure dimensions and access to food.

If keeping more than one frog:

• Provide adequate vertical climbing space.
• Include several resting places and areas of cover.
• Ensure that every frog can access food.
• Monitor for persistent aggression or stress.
• Quarantine new arrivals separately before considering introductions.
• Separate animals when illness, injury or incompatible behaviour occurs.

Avoid housing frogs of substantially different sizes together if there is a risk of injury or feeding competition. Do not assume that Borneo Eared Tree Frogs can safely share an enclosure with unrelated species.

Handling and Safety

Borneo Eared Tree Frogs are best regarded as observation animals rather than pets for frequent handling.

Amphibian skin is sensitive and permeable, and residues from soaps, lotions and other substances can be harmful. Unnecessary handling can also cause stress or injury.

Follow these precautions:

• Avoid unnecessary handling.
• Use appropriate clean, non-powdered gloves when essential handling is required.
• Follow suitable amphibian-handling guidance for necessary transfers.
• Keep the frog away from children and household pets.
