Description
Eleocharis acicularis, commonly known as Dwarf Hairgrass, is one of the most popular carpeting plants in aquascaping. Its thin, grass-like leaves create a soft, flowing effect, mimicking natural underwater meadows. This low-growing, fast-spreading plant forms a dense, vibrant green carpet, making it an excellent choice for foreground coverage in planted tanks.
Fast Growth & Easy Maintenance
Eleocharis acicularis thrives in moderate to high lighting, with CO₂ supplementation significantly improving its growth rate and density. It propagates naturally via runners, making it a low-maintenance option for aquarists seeking a seamless, lush foreground. While it can adapt to low-tech setups, it flourishes best in nutrient-rich substrates with consistent fertilization. For aquarists looking to achieve a vibrant, natural-looking carpet, Eleocharis acicularis is a must-have.
