Umbrella Hairgrass

Eleocharis vivipara

Plantae›Tracheophyta›Magnoliopsida›Poales›Cyperaceae

📍 Worldwide

Eleocharis Vivipara, Umbrella Hairgrass, is uniquely different from other hairgrass species — when grown submerged its slender stems branch repeatedly into arching, umbrella-like tufts rather than simple grass blades, creating a highly textural midground accent. Each stem tip can produce plantlets that anchor to substrate, aiding natural propagation. It needs moderate light and benefits from CO2.

Common Diseases

Algae Overgrowth

Symptoms

Green, brown, or black algae coating stems and leaves; reduced light penetration; stunted growth

Treatment

Increase water flow, reduce light duration to 8-10 hours daily, perform 30-40% water changes weekly, add algae-eating fish (Otocinclus) or shrimp (Red Cherry Shrimp), and manually remove affected portions

Nutrient Deficiency

Symptoms

Yellowing or pale stems, slow growth, weak branching, leaf discoloration

Treatment

Dose all-in-one fertilizer (Thrive, Flourish) 1-2 times weekly; ensure CO2 injection at 20-30 ppm; perform regular water changes to replenish macronutrients; consider upgrading to nutrient-rich aquasoil

Stem Rot

Symptoms

Blackening or mushy stems, foul odor, plant collapse, deterioration from base upward

Treatment

Improve water circulation with increased aeration; reduce organic waste through more frequent water changes; remove affected stems immediately; ensure substrate is not compacted; maintain stable temperature and pH

Melting

Symptoms

Rapid tissue breakdown, transparent or translucent stems, plant dissolving despite good conditions

Treatment

Gradually acclimate plant to new tank conditions over 2-3 weeks; maintain stable parameters (pH 6.5-7.5, temperature 20-28°C); ensure adequate CO2 and lighting; perform 25% water changes twice weekly until recovery
