🌿 Overview

Eleocharis vivipara is a soft, creeping aquatic plant native to tropical South America. Popular in aquascaping, it is known for its thin, grass-like leaves that form dense carpets in the foreground or midground.

This plant is moderately beginner-friendly, making it suitable for low-tech setups, though its growth rate, density, and appearance are greatly improved with high lighting, CO₂ supplementation, and nutrient-rich substrates.

🍃 Appearance

• Thin, bright green grass-like blades forming dense mats
• Height: 5–15 cm, depending on growth conditions
• Spreads horizontally via creeping stems and rhizomes
• Adds soft, flowing texture to aquascapes
• Ideal for foreground, midground, shrimp tanks, and nature-style aquariums

🌿 Plant Type (Hard/Soft)

• Type: Creeping / carpeting plant
• Category: Soft aquatic plant
• Growth rate: Moderate, faster with CO₂ and high light

🌡️ Ideal Water Temperature

• 20°C – 28°C (68°F – 82°F)
• Prefers stable tropical freshwater conditions

💡 Lighting Conditions

• Moderate to high lighting recommended
• High light promotes compact, dense carpets and vibrant green color
• Low light slows growth and elongates blades

🌿 CO₂ Requirement

• Optional but recommended
• CO₂ enhances growth rate, carpet density, and blade color
• Can survive without CO₂, suitable for low-tech setups

⚗️ Ideal pH Level

• pH: 6.0 – 7.5
• Slightly acidic to neutral water preferred

💧 Other Requirements

• Substrate: Fine-grained and nutrient-rich for strong rooting
• Fertilization: Benefits from liquid fertilizers and root tabs
• Water hardness: Soft to moderately hard
• Regular trimming promotes horizontal growth and prevents leggy blades
• Prefers stable water parameters for healthy, lush growth

🌱 Propagation

• Propagates via creeping stolons / rhizomes
• New shoots form along runners to expand carpets
• Can be divided and replanted to cover larger areas
• High light and CO₂ accelerate spread and compact mat formation

💡 Do You Know?

Eleocharis vivipara is widely used in aquascaping as “Hairgrass” because of its fine, delicate blades that mimic natural riverbeds. It is a favorite among hobbyists for nano tanks, foreground carpets, and creating natural aquascapes. It also provides hiding spots for shrimp and fry while enhancing the tank’s aesthetic.
