Gastrophrynoides borneensis

Geographical Origin and Habitat: Native to East Malaysia (Sarawak, Borneo). It primarily occurs in moist leaf litter and on moss-covered rocks of submontane hill forests. It lives mostly concealed within leaf litter or burrowed inside moist soils.

Taxonomy and Genetics: Belongs to the Microhylidae family, genus Gastrophrynoides. This group consists of narrow-mouthed frogs highly adapted to specific fossorial or semi-arboreal microhabitats.

Behavior and Habits: Primarily nocturnal and secretive. It spends the daytime hours buried under the substrate or hidden beneath leaf litter, emerging to forage and breed during heavy seasonal rains.

Morphology: Features a plump, rounded body reaching about 3.5 cm. Skin texture ranges from smooth to warty with cryptic colors. Males are smaller than females and exhibit distinct vocal sacs during the breeding season.

Terrarium Setup: Provide a horizontal terrarium with a deep (10-15 cm) layer of loose, damp substrate such as coconut fiber and sterile peat moss. Add cork bark hides, dry leaves, and flat shelters to create shaded spots.

Lighting and Heating: Maintain daytime temperatures around 25.0°C and night temperatures at 22.0°C. Provide a 12-hour light cycle; a low-intensity UVB source is recommended to support general health.

Humidity and Hydration: Maintain relative humidity between 80.0% and 90.0%. Mist regularly with dechlorinated water and supply a very shallow water dish to prevent drowning risks.

Feeding and Supplementation: Strictly insectivorous. Offer gutloaded crickets, roaches, fruit flies, and small worms. Dust prey with high-quality calcium and vitamin D3 twice a week to support skeletal structure.

Compatibility: Best kept in a species-specific setup. Small groups of similar size can cohabitate, avoiding competition or accidental cannibalism.

Health and Common Diseases: Highly susceptible to bacterial skin infections (red leg disease) if ventilation is poor or the substrate is soiled. Regularly check skin condition and hydration levels.
