• Origin: Sri Lanka
• Placement in Tank: Midground to background
• Height: 10-30 cm (4-12 inches)
• Growth Rate: Slow to moderate
• Lighting Requirement: Low to Medium. Higher lighting can encourage more vibrant red coloration.

Planting and Maintenance Tips

• Substrate: Plant in a nutrient-rich substrate to support its strong root system. Root tabs can be used if you have plain gravel or sand.
• Planting: Use tweezers to gently plant the roots into the substrate after removing any rock wool or gel from tissue cultures.
• "Crypt Melt": The plant is sensitive to sudden changes in water parameters and may experience a period of melting (leaves decaying) when first introduced to a new aquarium (known as "crypt melt"). This is normal; maintain stable conditions, and it will typically recover and grow back.
• Maintenance: Minimal trimming is needed. Simply remove older or damaged leaves to maintain appearance.
• Coloration: While adaptable to low light, providing a nutrient-rich environment, medium light, and optional CO2 will help the plant achieve a more robust red/brown color and faster growth.
