C30 Eleocharis acicularis, commonly known as Hairgrass, is a timeless aquascaping plant widely used in Iwagumi and nature-style aquariums. Native to wetlands and riverbanks across the world, this plant features longer, flowing grass-like blades compared to Eleocharis parvula, giving aquascapes a more dynamic and natural appearance. It spreads through runners and gradually forms dense carpets when provided with nutrient-rich substrate, stable water conditions, and adequate lighting. While CO₂ injection is optional, it significantly improves growth rate, carpet thickness, and overall health. Eleocharis acicularis is adaptable and suitable for both low-tech and high-tech planted tanks, though medium to high light is recommended to prevent excessive vertical growth. The plant is completely shrimp-safe and fish-safe, making it ideal for community aquariums and shrimp tanks.
