- Country of Origin: Sri Lanka
Essentials
- Light: Low to moderate; adaptable to different lighting conditions, but moderate light encourages optimal growth.
- Water: Prefers slightly acidic to neutral water with a pH of 6.0–7.5. Thrives submerged and adapts to emersed setups.
- Temperature: 72–82°F (22–28°C).
- Soil: Grows well in nutrient-rich substrates; a fine-gravel or sandy substrate is ideal for its root system.
- Placement: Ideal for the foreground to midground in aquascapes, providing texture and color contrast with its narrow leaves.
Features
- Size: Typically grows up to 4–8 inches (10–20 cm) tall, depending on conditions.
- Rate: Slow-growing; minimal maintenance required.
- Foliage: Slender, lanceolate leaves that are bright green, adding a fresh appearance to the aquarium.
- Flowering: Produces small, inconspicuous spathes when grown emersed, particularly in ripariums or vivariums.
Care
- Fertilizer: Benefits from regular fertilization; root tabs are effective due to its heavy root-feeding nature. CO₂ supplementation is optional but can enhance growth.
- Pruning/Propagation: Minimal pruning needed; remove dead or decaying leaves to maintain appearance. Propagates through runners that develop new plantlets; these can be left to form a dense cluster or separated and replanted.
- Special Tips: Avoid sudden changes in water parameters to prevent "crypt melt," a condition where leaves deteriorate. Once acclimated, it is a hardy plant that can tolerate a range of conditions.
