Tiger-legged Monkey Frog

Geographical Origin and Habitat: Found in the highly humid lowland primary rainforests of the Amazon Basin, spanning Peru, Ecuador, Colombia, and Brazil. Unlike its arid-dwelling relative *Phyllomedusa sauvagii*, this monkey frog inhabits dense, canopy-covered forests, slowly walking along thin vines and branches to navigate its environment.

Taxonomy and Genetics: A slender and elongated frog, adults reach about 4 to 5 cm in length. The dorsum is a vibrant leaf-green, providing excellent camouflage, while the hidden inner thighs and flanks feature a striking pattern of bright orange and black tiger-like stripes that serves as a flash coloration defense. Females are typically larger and stouter than the more slender males.

Behavior and Habits: A nocturnal and arboreal species that remains quiet and well-camouflaged during the day, pressed flat against leaves. At night, it becomes active, moving with slow, hand-over-hand climbing motions using its opposable thumbs. Breeding involves guttural chuckling calls from males and the creation of leaf nests suspended over water, where eggs are deposited in a gelatinous mass.

Morphology: Sexual dimorphism is characterized primarily by size, with adult females being significantly larger and heavier, particularly when gravid, whereas males are smaller, more slender, and possess calling vocal sacs.

Terrarium Setup: Requires a spacious, vertically oriented terrarium (minimum 45x45x60 cm). The enclosure should be heavily decorated with thin diagonal branches, vines, and broad-leafed live plants (such as *Philodendron* or *Pothos*) to provide resting sites. A clean water area or large bowl at the bottom is necessary, along with a bio-active substrate containing springtails and isopods to process waste.

Lighting and Heating: Prefers warm, tropical temperatures of 25–27°C during the day, with a nighttime drop to 21–23°C. High quality ventilation is crucial to prevent stagnant, overheating conditions which can be fatal. A 5% UVB light source is highly recommended to promote proper calcium metabolism and prevent metabolic bone disease.

Humidity and Hydration: Humidity levels must be kept high, around 80–90%, using automated misting systems or daily manual spraying with declorinated or reverse osmosis water. Good ventilation is essential to ensure that the environment dries slightly during the day and avoids damp, stagnant conditions that lead to bacterial skin infections (such as red-leg syndrome).

Feeding and Supplementation: Exclusively insectivorous, feeding on appropriately sized crickets, roaches, and flies. Food items should be dusted with calcium and vitamin D3 supplements three times a week for juveniles, and once or twice a week for adults, to prevent metabolic bone disease and support skeletal health.

Compatibility: Highly peaceful and gregarious, they can be housed in small groups or harems without aggression. They are entirely safe to keep together as long as adequate space is provided, though they should not be mixed with other amphibian species to prevent stress, pathogen transmission, or hybridization.

Health and Common Diseases: Skin is highly permeable and sensitive; they should never be handled with bare hands, as oils, soap residues, and human body heat can cause severe toxic shock. Stress from inadequate hiding places or handling can lead to snout rubbing against glass, causing abrasions that may become infected. Maintain strict terrarium hygiene to avoid bacterial infections.
