Cyperus helferi 133A is a graceful, grass-like aquatic plant often used in aquascaping for its long, flowing, ribbon-like leaves that add movement and texture to the aquarium. Native to Thailand, it thrives best in moderate to high lighting with nutrient-rich substrate and benefits greatly from CO₂ supplementation to achieve healthy, lush growth. Without CO₂, it grows more slowly and may struggle in low-light setups, making it more suitable for intermediate to advanced aquarists. It prefers stable, clean water conditions with good circulation and should be planted in the midground or background, where its arching leaves can sway in the current. Propagation occurs through runners or plant division, and while slow to establish, once settled it creates an elegant, natural aquascape centerpiece.
