Species description
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. 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.
Care, breeding and tankmates
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. 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.

It is typically used as a striking accent plant in the foreground to midground. Ensure it is placed in an open area where it won't be overshadowed by faster-growing surrounding plants.
It forms a rigid rosette with slightly broader and greener leaves compared to E. cinereum. Over time, mature specimens can develop a small, thick stem-like base.
This is a relatively slow-growing plant. It takes its time to form a substantial rosette and settle into a new environment, requiring patience from the aquascaper.
Eriocaulon sp. "Goiás" requires a deeply enriching, slightly acidic substrate environment to support its rigorous growth and complex root system. An active aqua soil that buffers the pH and provides abundant macronutrients is the ideal choice for cultivating this rare specimen. A substrate depth of 6-8 cm is highly recommended, giving its substantial roots ample room to spread, anchor, and feed. Ensuring the soil remains loose and highly fertile is key, as this plant depends heavily on its roots to uptake the minerals necessary for its distinctive appearance.
It thrives with consistent liquid dosing of micro and macro elements. While it feeds heavily from the roots, CO2 injection and liquid nutrients are highly recommended for optimal development.
It relies heavily on root nutrient uptake. Planting in a rich aquasoil and providing regular replenishment with root tabs are key to its long-term success.
Minimal trimming is needed. The primary maintenance involves simply plucking away older, deteriorating leaves near the base to prevent algae buildup and maintain a tidy appearance.
It propagates by producing offsets or splitting the crown when mature. Carefully divide the small plantlets from the mother plant using a sharp blade and replant them.
It is prone to melting during the initial acclimation phase or if subject to sudden parameter shifts. It demands soft, acidic water and unshaded, intense lighting to thrive.
It serves as an excellent structural accent or focal point in the foreground. Its distinct geometric shape adds immense visual interest and contrast to typical carpeting plants.
