Species description
Geographical Origin and Habitat: Comes from the state of Goiás in Brazil. It grows in extremely soft, acidic, and clear oligotrophic waters, often in sandy areas exposed to direct sunlight along the waterways of the Brazilian highlands.
Taxonomy & Genetics: It is part of the Eriocaulaceae family and the genus Eriocaulon. It is a species not yet formally described, known by the name of its region of origin. It has a highly specialized genetics for living in mineral-poor waters.
Physical Structure: It develops a very rigid and flattened leaf rosette that grows almost flush with the ground. The leaves are thick, lanceolate, and curved downwards, arranged in concentric circles that form a perfect geometric star.
Color & Texture: It has an intense emerald green coloration. The texture is leathery and rigid, very different from the softness of other aquatic plants, which makes it immediately recognizable.
Care, breeding and tankmates
Lighting & CO2: Requires extremely strong lighting. CO2 must be consistently supplied at medium-high levels to support its photosynthesis and general health.
Nutrition & Substrate: A fertilized, acidic substrate is a mandatory requirement. The roots draw most of the nutrients from the substrate; adding tabs rich in iron and phosphates is recommended.
Water Chemistry: Prefers very soft (KH 0-2) and highly acidic water (pH 4.5-6.5). Water conductivity must be kept low. Temperature between 20 and 28 °C.
Space Management & Placement: Place in the foreground or midground. Given its compact size and very slow growth, it is suitable for small spaces, but requires free space around it.
Pruning: Pruning is almost non-existent. Carefully remove old or damaged leaves at the periphery of the rosette to maintain aesthetic appearance.
Risks & Diseases: It is one of the most demanding plants. A sudden increase in water hardness or pH can lead to the rapid collapse of the plant and melting of the leaves.
