Eleocharis pusilla, often called Dwarf Hairgrass or Pusilla Hairgrass, is a delicate and compact foreground plant prized for its fine, bright green, grass-like leaves. Native to Southeast Asia, it grows in tight, dense clumps that can form lush carpets in aquariums, making it a favorite for creating natural, flowing landscapes in aquascapes.
This species is moderate in care and thrives under moderate to high lighting with nutrient-rich substrate. CO₂ supplementation encourages faster growth and denser coverage.
