Species description

Geographical Origin and Habitat: Distributed in the humid lowland rainforests of the Ecuadorian Amazon and Peru. It lives in the leaf litter, near small streams and damp root systems.
Taxonomy and Genetics: Family Dendrobatidae. Commonly known as the Ecuadorian Poison Frog. Its scientific name "bilinguis" refers to the dual notes in the male's call. It is a prized species among experienced hobbyists.
Behavior and Habits: Active diurnal species. Very lively, they spend their day foraging in the leaf litter. Males produce a metallic, double-note call to attract females. Eggs are laid on dry leaves, and males carry the hatched tadpoles on their backs to nearby pools.
Morphology: Small frog, reaching about 2.5 cm in length. Features a striking color pattern: a dark body with bright red or orange spots on the back, yellow spots on the limbs, and a marbled turquoise-blue belly. Females are slightly larger and rounder than males.

Care, breeding and tankmates

Terrarium Setup: Requires a terrestrial terrarium of at least 60x45x45 cm. Provide a thick drainage layer (clay balls) covered with organic soil and a dense layer of leaf litter (oak or Catappa). Include cork bark and coconut shells for hiding and nesting.
Lighting and Heating: Maintain temperatures between 25-27°C during the day, dropping to 21°C at night. Provide 5% UVB lighting to prevent metabolic bone disease. Temperatures above 30°C are lethal.
Humidity and Hydration: Keep humidity levels high (80-90%) with daily misting using reverse osmosis water. Good ventilation is essential to prevent stagnant conditions and bacterial diseases like Red Leg syndrome.
Feeding and Supplementation: Strictly insectivorous. Feed daily with small prey like fruit flies (Drosophila melanogaster and D. hydei) and springtails. Dust prey with calcium and vitamin D3 supplements three times a week.
Compatibility: Best kept in single pairs (1 male, 1 female) due to female territoriality and physical competition. Avoid mixing with other dendrobatid species to prevent stress or hybridization.
Health and Common Diseases: Avoid direct handling as soap residues and oils on human skin are highly toxic. Panicked frogs can suffer snout-rubbing injuries from colliding with the glass. Maintain strict enclosure hygiene.
