Giant Hairgrass (Eleocharis montevidensis) is a striking, tall-growing grass that brings a graceful, windswept look to freshwater aquariums. Its long, thin blades sway with the current, creating a dynamic, natural feel that works especially well in nature-style and biotope aquascapes. It grows from runners and can form loose, grassy thickets that provide cover for fish and shrimp.
