Bassler's Poison Frog

Geographical Origin and Habitat: Endemic to central Peru, along the eastern slopes of the Andes mountains, specifically in the regions of Huánuco, San Martín, and Pasco. It inhabits wet montane and pre-montane tropical rainforests at elevations between 200 and 1200 meters. They are frequently found near rocky streams, humid ravines, and waterfalls, hopping among wet rocks, tree roots, and leaf litter.

Taxonomy and Genetics: Belongs to the class Amphibia, order Anura, family Dendrobatidae, and genus Ameerega (formerly placed in the genus Epipedobates). Described by Melin in 1941. It exhibits high geographical variability, with several distinct color morphs featuring yellow, chrome-green, or orange stripes. Genetic makeup reflects the evolutionary isolation of Andean valleys.

Behavior and Habits: Diurnal and predominantly terrestrial, though they frequently scale wet boulders and low branches. Males produce a loud, distinctive, trilling advertisement call to attract females. Unlike the bolder Dendrobates species, Ameerega frogs are generally shy and very fast, darting into rocky crevices or under logs at the slightest disturbance.

Morphology: One of the larger poison dart frogs, with adults reaching lengths of 3.5 to 5 cm (1.4-2 inches). It features a slender body with long limbs adapted for jumping. The typical coloration consists of a black or dark brown dorsum accented by brilliant longitudinal stripes ranging from gold to turquoise. The belly is dark, marbled with electric blue.

Terrarium Setup: Requires a spacious terrarium, ideally 80x45x50 cm (32x18x20 inches) for a pair or small group. The layout should replicate a rocky stream bank, utilizing smooth stones, cork bark, moss, and a well-drained substrate covered with leaf litter. Large mesh ventilation areas are critical to prevent stagnant, humid air.

Lighting and Heating: Extremely sensitive to high temperatures. Daytime temperatures must be kept cool, between 22°C and 24°C (71-75°F), with a night drop to 16-19°C (60-66°F). Temperatures consistently exceeding 26°C (79°F) are highly dangerous and can quickly cause death. Use low-intensity LED lighting and a shaded 2.0 UVB source.

Humidity and Hydration: Maintain relative humidity between 80% and 90%. Mist the vivarium 2-3 times daily with reverse osmosis water. While high humidity is essential, air circulation must remain high. Providing a shallow, slow-moving water feature or stream (no deeper than 1 cm) is highly beneficial, as they enjoy soaking.

Feeding and Supplementation: Diet consists of live micro-insects. They can handle slightly larger prey than smaller dart frogs, including Drosophila hydei, small crickets, springtails, isopods, and freshly hatched flour beetles. Dust all prey insects at every feeding with a high-quality calcium and multivitamin powder containing Vitamin A.

Compatibility: Can be kept in small groups (e.g., a trio) if the enclosure is sufficiently large and complex, as they exhibit less severe conspecific aggression than Dendrobates. Do not co-house with different frog species or different Ameerega morphs to avoid cross-contamination and stress.

Health and Common Diseases: Heat stroke is the most critical threat, leading to rapid lethargy and death. Stagnant air combined with high humidity can cause bacterial skin infections. Spindle leg syndrome in developing tadpoles and nutritional deficiencies in adults are prevented by using fresh, high-quality dietary supplements.
