Eriocaulon sp. "Vietnam" is not yet known for a long time in Europe, however it has already proved to be an easy aquarium plant - in contrast to a number of other Eriocaulon rarities in the aquarium hobby. This plant, not yet determined to species, was originally found in the Vietnamese province Thanh Hoa. It is a medium-sized, about 15-30 cm tall Eriocaulon with relatively broad, medium-green, arching leaves, resembling Eriocaulon sp. "Goias".

This grass-like plant still grows with medium lighting and is even said to be suitable for hard water. However, a nutrient-rich substrate and a not too low CO2 concentration in the water column (at least 20 mg/l) are surely very conducive for its growth. With time, this plant forms a dense "grass tussock" with a number of leaf rosettes and can be divided into several single plants for propagation.

Eriocaulon sp. "Vietnam" can be used in aquascaping similarly to Blyxa japonica - e.g. as a meadow-like stand in the midground, linking the background with low ground covers in the foreground, or as scattered tufts between hardscape elements. In contrast to similar rosette plants such as Sagittaria subulata or Helanthium bolivianum, it does not develop runners, making its handling easy. This undemanding Eriocaulon surely deserves a wide distribution in the aquarium hobby.

Temperature: Ideally maintained between 72°F (22°C) and 82°F (28°C)

pH Level: Slightly acidic to slightly alkaline, within the range of 6.0 to 7.5

Water Hardness: Soft to moderately hard, with a range of 2 to 15 dKH

Lighting: Medium to high intensity lighting is recommended for optimal growth

CO2 Requirement: Moderate to high levels of CO2 supplementation are beneficial

Nutrient Level: A well-balanced nutrient-rich substrate or liquid fertilizer is recommended.

pairs well with small schooling fish like tetras, rasboras, and guppies.

Avoid combining it with aggressive or herbivorous species that may damage the delicate foliage.

Planting: Gently insert the plant roots into a well-prepared substrate, ensuring they are securely anchored.

Maintenance: Regularly check water parameters, lighting intensity, and CO2 levels to maintain optimum conditions for the plant's growth.

Pruning: Trim any dead or decaying leaves to maintain a clean and healthy appearance. Remove any excessive growth to prevent overcrowding.

Propagation: TCulture Eriocaulon sp Vietnam can be propagated by separating and replanting the offshoots that develop from the main plant.

Health and Disease: Monitor the plant for signs of nutrient deficiencies or diseases. Quarantine new additions to prevent potential contamination.
