Eriocaulon Vietnam care guide
Eriocaulon Vietnam (Eriocaulon sp. 'Vietnam') — high light, 22-28 °C, pH 4.5-6.5, CO2 recommended.
Overview
Eriocaulon Vietnam (Eriocaulon sp. 'Vietnam') is an aquatic plant of the family Eriocaulaceae, listed in the Aquairi knowledge base as an advanced-level species. It is typically grown under high light with pressurised CO2 injection on nutrient-rich aquasoil. A striking rosette-forming pipewort with fine needle-like leaves that radiate outward creating a spiky starburst appearance. One of the most visually distinctive foreground plants, but extremely demanding — requiring very soft acidic water, high CO2, and strong lighting.
Taxonomy
- Family: Eriocaulaceae
- Genus: Eriocaulon
- Scientific name: Eriocaulon sp. 'Vietnam'
- Common synonyms: Eriocaulon sp. Vietnam
Habitat
Eriocaulon is a genus of pipeworts (Eriocaulaceae) with around four hundred species worldwide, many in seasonally flooded fields and acidic, soft-water habitats of South and South-East Asia. In the Aquairi knowledge base, populations associated with this form are recorded from Vietnam.
Growth requirements
- Lighting: high
- CO2: recommended
- Temperature: 22-28 °C (72-82 °F)
- pH: 4.5-6.5
- GH: 0-3 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 10 cm
- Growth rate: slow
- Recommended placement: foreground
Placement
Midground accent forming a tight rosette of narrow leaves. A nutrient-rich substrate, soft water and CO2 are required for stable submersed growth. In the Aquairi knowledge base this form is recommended for the foreground under high light with pressurised CO2 injection, using nutrient-rich aquasoil.
Propagation
Flowering produces side shoots that can be separated from the parent rosette; division gives the most reliable propagation in the aquarium. Documented propagation techniques for this entry include: division of the parent plant.
Common issues
Sensitive to disturbance — replanting an established rosette often triggers melt, after which the plant slowly recovers. Soft, mineral-poor water with adequate CO2 reduces stress responses.
