Dwarf Hairgrass (Eleocharis sp.) – Live Aquarium Foreground Plant

Dwarf Hairgrass is a favorite among aquarium lovers for creating lush, natural green carpets. This low-growing foreground plant brings a clean, professional aquascape look to both small and large freshwater aquariums. With proper care, it spreads beautifully across the substrate, adding depth, oxygen, and a natural environment for fish and shrimp.

For best results, many aquascapers use the Dry Start Method to encourage faster rooting and denser carpet growth.
