Lilaeopsis brasiliensis (Brazilian micro sword) is a popular, grass-like foreground aquarium plant from South America, used to create a vibrant green lawn. It grows 4 to 7 cm tall, spreads via runners, and features flat, narrow leaves.
Lighting:
Moderate to high lighting is required to achieve a dense, compact carpeting effect.
Substrate:
Thrives best in a nutrient-rich aqua soil or fertilized substrate.
CO2 and Fertilization:
CO2 injection and regular liquid fertilizers (including iron) accelerate growth, though it can grow slowly without added CO2.
Water Parameters:
Prefers temperatures of 20 to 28°C (68 to 82°F) and a pH of 5.5 to 7.5. It also tolerates cool water and low-salinity brackish conditions.
Placement:
Position small clumps 2 to 3 cm apart in open foreground areas without shade.
Growth Rate:
Slow grower that requires patience to knit together into a full mat.
Pruning:
Occasional trimming encourages denser, horizontal runner growth.
