Species description
Geographical Origin and Habitat: This species is endemic to the limestone islet of Nosy Hara in northern Madagascar. It inhabits the dry leaf litter layer on the floor of dry deciduous forests and the crevices of karst limestone formations (tsingy) typical of the island, staying within centimeters of the ground.
Taxonomy and Genetics: Belongs to the Chamaeleonidae family, genus Brookesia. Formally described in 2012, it represents one of the most genetically and morphologically divergent chameleon species in Madagascar, exhibiting extreme insular dwarfism driven by the geographical confinement of its native islet.
Behavior and Habits: A diurnal, slow-moving, and incredibly cryptic animal. It spends daylight hours crawling slowly through leaf litter foraging for microscopic prey. At night, it climbs onto low twigs or grass blades just 5-10 cm above the ground to sleep, avoiding terrestrial predators.
Morphology: One of the smallest reptiles in the world, with adults reaching a total length of only 23 to 29 mm, tail included. It has a laterally compressed body resembling a dead leaf, a boxy head without prominent crests, and, in mature individuals, a characteristic orange-to-yellowish tail.
Care, breeding and tankmates
Terrarium Setup: Requires a small bioactive terrarium (e.g., 30x30x30 cm) arranged with extreme precision. The substrate must consist of natural organic soil covered by a thick layer of dried oak or catappa leaf litter. Add very thin twigs, moss, and small live plants to provide essential nocturnal roosting spots.
Lighting and Heating: Demands moderate and stable temperatures, as overheating is quickly fatal. The ideal daytime temperature is 22-24 °C, with a slight drop at night to 18-20 °C. Provide a very low-output UVB light source (e.g., shaded 2.0 or 5.0) alongside standard LED fixtures for plant growth.
Humidity and Hydration: Humidity levels must be kept high, between 70% and 85%. Fine misting with reverse osmosis water is required daily. The chameleon drinks only water droplets that form on leaves and twigs; due to its micro size, heavy water droplets can actually pose a physical hazard.
Feeding and Supplementation: Extremely complex diet consisting of microscopic live prey. They accept springtails, flightless fruit flies (Drosophila melanogaster), pinhead crickets, and aphids. Dust prey with pure calcium twice a week and a high-quality multivitamin with D3 once a month.
Compatibility: Must be housed strictly solitary (one individual per enclosure) or at most in a well-established breeding pair in larger setups, with close monitoring. The presence of any other animal (including small geckos or predatory insects) poses a direct and fatal threat.
Health and Common Diseases: Highly delicate and sensitive to handling stress (must never be handled unless absolutely necessary). Dehydration and overheating are the leading causes of rapid death. Maintain strict climate control and ensure excellent ventilation to prevent stagnant air buildup.

The catalog's scalar value is 1.99 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 1.99 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.
