Dyeing Poison Dart Frog "Pic Matecho"

Geographical Origin and Habitat: This specific geographic morph of Dendrobates tinctorius is native to northern French Guiana, restricted to the forested hills surrounding Pic Matecho. It inhabits the humid leaf litter of primary tropical rainforests. It lives primarily on the forest floor among wet decaying leaves, exposed tree roots, and plant debris, but can also climb mossy fallen tree trunks and low branches near epiphytic bromeliads.

Taxonomy and Genetics: Belongs to the family Dendrobatidae, genus Dendrobates. Dendrobates tinctorius is a highly polymorphic species; the 'Pic Matecho' population represents a geographically isolated lineage that maintains stable color traits due to the ecological barriers of the hills. Genetically close to the classic 'Matecho' morph, it shows consistent minor variations in the shape of its yellow and black markings.

Behavior and Habits: Diurnal and terrestrial in its habits. It is an active, inquisitive, and highly territorial frog, especially among males competing for feeding territories and breeding sites. Males produce a soft, buzzing call to attract females. It spends its active hours foraging on the forest floor, displaying bold behavior when housed in well-structured terrariums.

Morphology: One of the largest poison dart frogs, with adults measuring between 5.0 and 6.0 centimeters, with females being larger and heavier than males. The body is vertically compressed with strong limbs for climbing. The coloration of the 'Pic Matecho' morph features a brilliant yellow-orange dorsal saddle with very few black spots, while the limbs and belly are a deep cobalt blue with black speckles.

Terrarium Setup: Requires a humid bioactive terrarium measuring at least 50x50x50 cm for a pair. The substrate must consist of coconut fiber, peat moss, and sphagnum moss, topped with a generous layer of oak or Catappa leaves to protect their sensitive skin. Incorporate live plants (such as Neoregelia bromeliads, Philodendron, and Ficus pumila) and cork bark to create hiding spots and climbing areas.

Lighting and Heating: Daytime temperature should be maintained between 24°C and 26°C (75.2°F - 78.8°F), with a slight drop to 20-22°C (68°F - 71.6°F) at night. Avoid temperatures exceeding 28°C (82.4°F) as it can quickly be fatal. Lighting should support plant growth (LED or T5), and a low-output UVB bulb (2.0%) is highly recommended to assist in vitamin D3 synthesis.

Humidity and Hydration: Humidity must be kept high, between 80% and 95%. This is achieved through daily misting, either manually or using an automatic misting system. Avoid standing water on the substrate; a proper drainage layer (clay balls and mesh) is mandatory. Provide a shallow water dish (only a few millimeters deep) for the frogs to soak.

Feeding and Supplementation: In captivity, they feed exclusively on tiny live insects. The staple diet consists of flightless fruit flies (Drosophila melanogaster and D. hydei), springtails, pea aphids, and pinhead crickets. Every feeding must be dusted with a high-quality calcium and multivitamin supplement containing Vitamin A (retinol) to prevent nutritional deficiencies.

Compatibility: Best kept in established male-female pairs. Females are highly competitive and aggressive toward one another, often fighting for dominance or the male's attention, which can lead to stress or death. Cohabitation with other morphs of D. tinctorius or other frog species must be avoided to prevent stress and cross-breeding.

Health and Common Diseases: Major health risks include spindle leg syndrome in tadpoles caused by poor parental nutrition, and fungal skin infections (Chytridiomycosis) due to poor ventilation or unsanitary conditions. Maintaining stable humidity, proper supplementation, and cleaning leaves and glass regularly will prevent most health issues.
