Eriocaulon sp. ‘Vietnam’ – Vietnam Eriocaulon

Eriocaulon sp. ‘Vietnam’ is a rare and striking foreground plant, admired for its fine, rosette-like tufted leaves that form dense carpets in aquariums. Native to Southeast Asia, it is highly sought after in the aquascaping hobby for creating delicate, textured foregrounds and natural-looking riverbed effects. This plant requires stable, nutrient-rich conditions and moderate to high lighting to thrive.

Lighting

• Moderate to High Lighting: Bright light encourages compact, dense growth. Under low light, the plant may grow taller and sparse, losing its attractive rosette shape.

Water Parameters

• Temperature: 20–26 °C; stable, moderate temperatures are ideal.

• pH: 6.0–7.5, slightly acidic to neutral water supports healthy growth.

• Water Hardness: Soft water (2–10 dGH) preferred for optimal growth.

Substrate

• Nutrient-Rich Substrate: Thrives in fine aquasoil or enriched substrates; root tabs recommended for inert gravel.

• Depth: 3–5 cm (1–2 inches) substrate depth allows proper rooting and rosette formation.

CO₂ and Fertilization

• CO₂: Recommended for faster, denser growth and healthy leaf development.

• Fertilization: Regular dosing of macronutrients and iron-rich micronutrients promotes lush, vibrant growth.

Growth and Maintenance

• Growth Rate: Slow; patience is required to establish dense carpets.

• Pruning: Remove damaged leaves carefully to maintain neat rosettes. Separate and replant healthy shoots to expand coverage.

Placement in Aquarium

• Foreground: Ideal for delicate carpets and detailed foreground scapes, complementing rocks and driftwood.

Propagation

• Division: Forms new rosettes from runners. Separate mature plants to propagate and expand the carpet.

Water Flow and Circulation

• Moderate Flow: Ensures clean leaves, prevents debris accumulation, and encourages healthy growth.

Algae Control

• Prevention: Balanced light and nutrients reduce algae on delicate leaves. Avoid sudden changes in light or water chemistry.

Compatibility

• Community Tank Friendly: Safe with most peaceful fish and invertebrates. Avoid digging or burrowing species that may disturb the roots.

With proper care, Eriocaulon sp. ‘Vietnam’ will form a delicate, textured foreground, giving your aquascape a natural, riverbed-like appearance.

Interesting Fact: Eriocaulon sp. ‘Vietnam’ is prized for its adaptability in aquascapes with high light and CO₂. Its tufted, rosette growth not only looks visually stunning but also provides hiding spots for shrimp and small fish, enhancing both aesthetics and ecological balance.
