Species description
Geographical Origin and Habitat: This species is distributed along the coastal plains of East Africa, found in Kenya, Tanzania, Malawi, Mozambique, Zimbabwe, and eastern South Africa. It inhabits humid savannas, seasonally flooded grasslands, freshwater swamps, and dense reed beds. It lives primarily on the leaves of reeds, sedges, papyrus, and other emergent vegetation near permanent or temporary pools.
Taxonomy and Genetics: Belongs to the family Hyperoliidae, genus Afrixalus. Described by Bianconi in 1849. This species is distinguished within its genus by the presence of small black spiny tubercles on the dorsum of breeding males. Genetic studies show a close relationship to the genus Hyperolius, but with specific adaptations for folding leaves during egg deposition.
Behavior and Habits: Primarily diurnal and arboreal. It spends the hot hours of the day clinging vertically to reed leaves, camouflaged by its longitudinal stripes. At night, it becomes active to hunt small insects and breed. Males produce loud, distinctive breeding calls that sound like metallic tapping or rapid clicks to attract females near the water.
Morphology: A small frog, with adult specimens measuring between 3.0 and 4.0 centimeters (1.2-1.6 inches) in length. The body is slender and compressed, with large eyes featuring vertical pupils (a defining characteristic of the genus Afrixalus). The dorsal pattern consists of a dark brown central stripe flanked by two broad silver-white lateral bands running from the snout to the vent.
Care, breeding and tankmates
Terrarium Setup: Requires a vertically oriented terrarium (minimum 30x30x45 cm / 12x12x18 inches for a small group of 3-4 frogs). The substrate should consist of coconut fiber topped with damp sphagnum moss. It is essential to include tall, broad-leafed plants that mimic natural reeds (such as Sansevieria, Dracaena, Pothos, and vertical bamboo poles) for climbing and resting.
Lighting and Heating: Daytime temperature should be maintained between 24°C and 27°C (75.2°F - 80.6°F), with a night drop to 20-22°C (68°F - 71.6°F). Use a low-wattage basking bulb or heat emitter above the enclosure if needed. Provide a 2.0% UVB bulb for 10-12 hours daily to support calcium metabolism and simulate filtered sunlight.
Humidity and Hydration: Requires moderate to high humidity, between 60% and 80% during the day, peaking at 90% at night. Mist the enclosure once or twice daily with dechlorinated water. Provide a shallow, clean water dish at the bottom; the water must be replaced daily to prevent bacterial buildup which is harmful to their permeable skin.
Feeding and Supplementation: Insectivorous. Feeds on small live insects such as fruit flies (Drosophila melanogaster and D. hydei), pinhead crickets, springtails, and aphids. Dust prey with pure calcium three times a week for juveniles and once a week for adults, and a multivitamin supplement containing Vitamin A once a week to prevent deficiencies.
Compatibility: Can be housed in small monospecific groups in well-planted terrariums. They are peaceful toward conspecifics, though males may establish minor territorial calling sites during the breeding season. Do not house with other amphibian species to prevent stress and risk of pathogen transmission (such as chytrid fungus).
Health and Common Diseases: Vulnerable to dehydration (if humidity drops too low or fresh water is unavailable), bacterial skin infections due to poor substrate hygiene, and metabolic bone disease (MBD) from lack of calcium/UVB. Handling must be minimized and only done with wet hands or wet nitrile gloves.

The catalog's scalar value is 4 cm. The AmphiBIO v1 source reports a maximum adult measurement of 4 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.
