Species description
Geographical Origin and Habitat: Cornufer montanus is an amphibian endemic to the Solomon Islands archipelago, primarily found in high-altitude montane environments on islands such as Bougainville. It inhabits pristine cloud forests, living among dense leaf litter, mossy banks, and low vegetation near clean mountain streams under highly humid and cool conditions.
Taxonomy and Genetics: Belonging to the family Ceratobatrachidae, this species is classified under the genus Cornufer (formerly placed in Platymantis). Genetics of this group highlight significant island radiation and specialization, characterized by direct development, a reproductive strategy that bypasses the aquatic tadpole stage entirely.
Behavior and Habits: Chiefly nocturnal and terrestrial. During daylight hours, it remains hidden beneath damp leaf litter, rotting logs, or thick moss to prevent desiccation. At night, it emerges to forage for small invertebrates and engage in social calling. Males vocalize from low vegetation or ground level with soft, repetitive clicks.
Morphology: Features a robust, stocky body with a wide head and snout. Its limbs are adapted for crawling rather than climbing, lacking extensive webbing. The skin is moderately textured with small tubercles. Coloration consists of cryptic shades of brown, grey, and moss green, providing excellent camouflage against the forest floor.
Care, breeding and tankmates
Terrarium Setup: A humid forest terrarium (bioactive preferred) of at least 60x45x45 cm is required for a pair. The substrate should consist of organic soil, coconut husk fiber, and a thick top layer of sterilized leaf litter and sphagnum moss to retain moisture. Furnish with cork bark pieces, rotting wood, and live plants such as ferns and bromeliads.
Lighting and Heating: Unlike lowland tropical species, this montane frog requires cool temperatures. Day temperatures must be kept between 20°C and 24°C, dropping to 16°C-18°C at night. Temperatures exceeding 26°C can cause severe heat stress and mortality. Low-output LED lighting is sufficient; a 2% UVB source is beneficial.
Humidity and Hydration: Maintain relative humidity between 80% and 95% at all times. This can be achieved through automated misting systems or twice-daily manual misting using reverse osmosis or declorinated water. Provide a shallow water dish with clean water, ensuring it is easy for the frogs to exit. The substrate must not become waterlogged.
Feeding and Supplementation: Insectivorous. Feed a variety of live insects, including appropriate-sized crickets, fruit flies (Drosophila), roaches, woodlice, and springtails. Dust all feeder insects with high-quality calcium and vitamin D3 supplements twice a week to support bone health and prevent metabolic bone disease.
Compatibility: Best kept individually or in confirmed male-female pairs. They can exhibit territorial behavior, particularly males during the breeding season. Do not cohabitate with other amphibian or reptile species due to the risk of stress, pathogen transmission, or predation of smaller animals.
Health and Common Diseases: Highly vulnerable to chytridiomycosis (fungal infection) and bacterial skin infections if kept in unhygienic or saturated environments. Heat stress is a major risk factor in captivity. Keep a close eye on temperature probes and ensure adequate terrarium ventilation to prevent stagnant air pockets.
