Artbeschreibung
Geographical Origin and Habitat: This species is endemic to Negros Island in the Philippines. It inhabits primary and secondary tropical rainforests, ranging from lowland valleys to submontane foothills up to 900 meters above sea level, spending its life on the damp forest floor.
Taxonomy and Genetics: Belongs to the family Ceratobatrachidae and the genus Platymantis. It belongs to the terrestrial cluster of direct-developing species in the region. Eggs are deposited in hidden, damp terrestrial cavities under leaf litter or logs and hatch directly as froglets.
Behavior and Habits: Primarily terrestrial, crepuscular, and nocturnal. During the day, it remains hidden under leaf litter, rotting logs, or soil crevices. At night, it emerges to hunt crawling insects. Males vocalize from ground level or very low logs during rain.
Morphology: A medium-sized, stocky frog with a broad head and relatively short, powerful hind legs adapted for leaping across forest litter. The skin is granular with distinct ridges. Its cryptic coloration is composed of shades of brown, grey, and charcoal to mimic forest soil.
Pflege, Zucht und Mitbewohner
Terrarium Setup: Requires a horizontally oriented terrarium measuring at least 60x40x40 cm (24x16x16 inches) for a pair. Substrate should consist of a moist soil/peat mix 6-8 cm deep, covered with a thick layer of dried hardwood leaves (oak, catappa) and cork bark hides.
Lighting and Heating: Provide low-intensity LED lighting and a 2% to 5% UVB source. Maintain daytime temperatures between 22°C and 25°C (72°F-77°F) with a slight drop at night. Avoid under-tank heating pads as they can dry out the damp soil substrate rapidly.
Humidity and Hydration: Maintain high humidity levels between 80% and 90%. Mist the terrarium daily with reverse osmosis or dechlorinated water. Provide a shallow, broad water bowl for hydration, ensuring the water is changed daily and kept completely free of chlorine.
Feeding and Supplementation: A voracious feeder. Offer a variety of gut-loaded live insects like crickets, small roaches (Dubia), mealworms, and earthworms. Dust prey with calcium and vitamin D3 twice a week, and a complete herpetological multivitamin every two weeks.
Compatibility: Best kept in pairs. Since they are opportunistic ground predators, do not house them with smaller frog species that could be eaten, or with hyperactive tankmates that might disrupt their daytime rest cycles.
Health and Common Diseases: Vulnerable to bacterial skin infections if the substrate is allowed to become waterlogged and stagnant. Maintain a clean leaf litter layer and ensure the drainage layer functions. Monitor calcium intake to prevent Metabolic Bone Disease.

Amphibienprofil
- Diät
- Insectivore
- This species is primarily insectivorous in the wild, feeding on a wide variety of small forest invertebrates. In captivity, their diet should consist of appropriately sized crickets, fruit flies, and small worms. It is important to dust the feeder insects with calcium and vitamin supplements to ensure proper nutrition. Feeding them every other day is usually sufficient for adult frogs. Clean, fresh water must be available at all times.

- Lebensstil/Mikrohabitat
- Arboreal
- These amphibians lead a primarily terrestrial and scansorial lifestyle within tropical forest ecosystems. They navigate the complex structure of the forest floor, frequently climbing on small shrubs, roots, and rocks. A heavily planted terrarium with a deep substrate layer best replicates their natural habitat. They thrive in environments with very high humidity and dense vegetation. Consistent environmental conditions are key to keeping them healthy.
- Aktivitätszyklus
- Nocturnal
- They are predominantly nocturnal animals, becoming most active after the sun goes down. During the day, they remain well hidden in the damp, shaded parts of the forest floor to avoid desiccation and predators. Once night falls, they emerge to actively forage for small insect prey. Captive environments should mimic this cycle with appropriate lighting periods. A strict day and night cycle is crucial for their overall well-being.
- Sozialität
- Gregarious
- As small forest dwellers, these frogs are generally quite shy and reclusive by nature. They spend the majority of their time hidden among leaf litter, under decaying logs, or in the crevices of low-hanging vegetation. When threatened, they rely heavily on their natural camouflage to blend into the forest floor. They may vocalize during the breeding season with distinct calls to attract mates. Providing ample hiding spots in captivity helps reduce their stress levels.
- Reproduktion
- Direct development
- These frogs are known for their unique reproductive strategy, often involving direct development in moist terrestrial environments. Rather than having a free-swimming tadpole stage, females lay eggs in damp leaf litter. Inside the egg capsules, the embryos develop fully and hatch as miniature, fully formed froglets. This adaptation allows them to reproduce without relying on standing bodies of water. Maintaining adequate moisture in the breeding enclosure is strictly required.
- Toxizität
- Toxic
- No known toxicity to humans, but sensitive to chemical agents on the skin.
- Lebensphase
- Direct development
- Direct embryonic development: eggs are laid in moist leaf litter and hatch directly into tiny froglets.
- Handhabungstoleranz
- Display only
- Like most small frogs, they have delicate, permeable skin that can absorb harmful oils and salts from human hands. They should be considered a display-only species, with handling strictly avoided unless absolutely necessary for health evaluations or enclosure transfers.
- Brumation
- Nicht erforderlich
- Hailing from tropical environments, this species does not undergo brumation. They require a consistently warm and highly humid environment year-round, without significant seasonal drops in temperature.
- Häutung
- Periodic
- They shed their skin regularly, a process heavily dependent on maintaining high ambient humidity in the enclosure. Shedding happens quickly and discreetly, often at night, and the shed skin is almost always immediately consumed by the frog to recover nutrients.
