Species description
Geographical Origin and Habitat: Native to the dense primary and secondary rainforests of the Amazon Basin, with key populations distributed across Peru, northern Brazil, southern Colombia, and French Guiana. It is an strictly arboreal species that spends its life in the forest understory and canopy, heavily relying on water-filled bromeliads (phytotelmata) for shelter and breeding.
Taxonomy and Genetics: A member of the Dendrobatidae family under the genus Ranitomeya, commonly known as the Amazonian Poison Frog. Historically confused with Ranitomeya ventrimaculata, it was established as a distinct species based on acoustic analysis and genetic markers. It belongs to the 'thumbnail' group, with adult sizes ranging between 1.6 and 1.8 centimeters.
Behavior and Habits: Strictly diurnal, highly active, and agile. They spend their active hours climbing among leaves and hunting micro-insects. Males are territorial and defend their calling sites, emitting a short, metallic, buzz-like call to court females. Paternal care is highly developed: males carry hatched tadpoles on their backs to transport them to separate water pools.
Morphology: Possesses a striking aposematic coloration. The head and upper dorsum display brilliant fiery red-orange stripes forming a characteristic Y-pattern on a black background. The legs and underbelly are colored in electric blue or cyan, covered with a fine black reticulated mosaic pattern. Their toes are equipped with wide, sticky pads for climbing wet vertical leaves.
Care, breeding and tankmates
Terrarium Setup: Requires a vertically oriented terrarium, with minimum dimensions of 30x30x45 cm (12x12x18 inches) for a single breeding pair. It must be densely planted with live bromeliads, climbing vines, and ferns. Use a well-draining substrate (clay balls topped with coco-fiber and dried leaf litter). Provide hollow branches and cork bark. Leaf axils must contain clean water.
Lighting and Heating: Bright LED lighting is required to sustain live plants. A low-output 2% to 5% UVB source is highly recommended to promote vitamin D3 synthesis and prevent metabolic bone disease. Maintain daytime temperatures at 24-27°C (75-81°F) using heat mats if necessary. Provide a nocturnal temperature drop to 20-22°C (68-71°F). Avoid heat exceeding 29°C (84°F).
Humidity and Hydration: Humidity must remain consistently high, between 80% and 95%. This is best achieved using an automatic misting system spraying reverse-osmosis water 2 to 4 times daily. However, clean air circulation through fine mesh vents is mandatory to prevent stagnant, waterlogged conditions that lead to bacterial infections and skin rot.
Feeding and Supplementation: Strictly micro-insectivorous. Their diet in captivity consists of Drosophila melanogaster fruit flies, springtails, pea aphids, and newly hatched pinhead crickets. It is vital to dust all food at every feeding with a high-quality calcium and multivitamin supplement containing preformed Vitamin A, preventing spindle leg syndrome and malnutrition.
Compatibility: Best kept in single breeding pairs. Group housing is possible only in larger terrariums (minimum 45x45x60 cm) with multiple bromeliads to reduce territorial aggression, especially among females competing for nesting sites. Do not house them with other species of poison dart frogs to avoid hybridization and stress.
Health and Common Diseases: The primary care risks are rapid dehydration if humidity drops below 70% and fatal overheating during summer months (temperatures above 30°C/86°F are lethal). Because of their micro-size and permeable skin, they are strictly observation-only pets; handling with bare hands should never occur due to toxic residues on human skin.

The catalog's scalar value is 1.9 cm. The AmphiBIO v1 source reports a maximum adult measurement of 1.9 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
