Species description
Geographical Origin and Habitat: Atheris nitschei is native to the montane regions of Central and East Africa, ranging across Uganda, Rwanda, Burundi, and the Democratic Republic of the Congo. It inhabits humid biotopes at elevations between 1,500 and 3,000 meters, showing a preference for papyrus swamps and bamboo forests.
Taxonomy and Genetics: A member of the family Viperidae and the genus Atheris. Commonly known as the Great Lakes Bush Viper or Nitsche's Bush Viper. Its genetics are adapted to high-altitude montane and swamp ecosystems. The subspecies Atheris nitschei rungweensis was previously recognized but has been elevated to a full species.
Behavior and Habits: Nocturnal and arboreal, closely associated with highly humid, wet environments. It is an ambush predator that spends daytime hours hidden in dense shrubs, reeds, or papyrus stems. The species carries a highly active hemotoxic venom. Its strong prehensile tail is used to anchor itself while striking.
Morphology: One of the largest and most robust species in the genus Atheris, reaching lengths of up to 70-80 cm. It features a broad, triangular head that is distinct from the neck. Coloration is typically bright leaf green with bold black markings on the head (often V-shaped) and a black zig-zag pattern along the back.
Care, breeding and tankmates
Terrarium Setup: A spacious vertical terrarium of at least 60x50x80 cm is required. Furnish the enclosure with sturdy climbing branches, bamboo stalks, and live plants to replicate a dense wetland habitat. Use a moisture-retaining substrate such as peat moss and sphagnum moss. Secure locks are mandatory.
Lighting and Heating: Requires cool to moderate temperatures due to its high-altitude origin. Daytime temperatures should range from 21°C to 24°C, with a localized basking spot of 27°C. Nighttime temperatures must drop to 16-18°C. Provide a 2% to 5% UVB lamp on a 10-hour cycle, avoiding excessive heat.
Humidity and Hydration: Maintain high humidity levels between 75% and 85%. Spray the terrarium daily with clean water, preferably in the evening. Since they drink droplets off leaves rather than from a water bowl, daily misting is vital. Ensure proper cross-ventilation to prevent mold and stagnant air.
Feeding and Supplementation: Carnivorous. Feed appropriately sized frozen-thawed mice using long feeding forceps. Neonates may occasionally require scenting or small frogs to start feeding. Dust prey with calcium and vitamin D3 supplements once a month for adults.
Compatibility: Strictly solitary. Do not house together. The venom is medically significant and dangerous. Keep the terrarium locked and clearly labeled. Use proper snake hooks and handling gear for any maintenance or relocation. Keep emergency protocols handy.
Health and Common Diseases: Highly sensitive to temperatures above 28°C, which can cause fatal heat stroke. Susceptible to respiratory infections and scale rot if the enclosure lacks proper airflow while maintaining high humidity. Consult a specialized exotic animal veterinarian.

The catalog's scalar value is 75 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 75 cm for this species, recorded as total length (TL). 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.
