Rotala wallichii is a delicate and striking aquatic plant known for its finely branched, soft feathery leaves that transition from bright green to vibrant shades of pink and red under the right conditions. Native to Southeast Asia, this plant is popular for adding a pop of color and texture to aquascapes, particularly in the midground or background. Rotala wallichii requires a bit more attention and thrives best in high light and with CO2 supplementation, making it an excellent choice for aquarists with some experience who are looking to create a dynamic and colorful display.

Key Features:

• Feathery, Soft Leaves: Rotala wallichii has fine, needle-like leaves that form soft, dense whorls along its stems, creating a beautiful, bushy appearance.
• Vibrant Coloration: The foliage develops vibrant pink to deep red hues under high light conditions, adding a beautiful contrast to the greenery in the aquarium.
• Ideal for Midground or Background Placement: The plant’s tall, delicate growth makes it well-suited for the midground or background, where it can add a sense of height, movement, and vibrant color.
• Moderate Growth Rate: Rotala wallichii grows moderately fast when provided with the right conditions, making it perfect for filling space while also creating an attractive and lush layout.

Care Requirements:

• Lighting: Rotala wallichii requires high lighting to achieve its vibrant red coloration and compact, bushy growth. Without sufficient light, the plant may appear less colorful and grow less densely.
• CO2: CO2 supplementation is highly recommended to help Rotala wallichii thrive. Adding CO2 will significantly improve the plant’s growth rate and enhance the intensity of its colors.
• Water Parameters: This plant prefers softer water with a slightly acidic pH range of 5.5-7.0 and temperatures between 22-28°C. It is also sensitive to water quality, so maintaining stable conditions is crucial.
• Trimming: Regular trimming is necessary to maintain the plant’s compact appearance and to encourage bushy growth. Trimming also prevents the lower parts of the plant from becoming shadowed and losing leaves.

Planting Tips:

• Planting in Clumps: Plant Rotala wallichii in small clumps, spacing the stems slightly apart. This helps encourage even growth and ensures light can reach all parts of the plant.
• Propagation: To propagate, trim the top of the stem and replant it in the substrate. The cuttings will develop roots and continue to grow, creating a bushier and fuller appearance.
• Nutrient Requirements: Rotala wallichii has a higher nutrient demand, especially when grown under high light. Regular fertilization, particularly with micronutrients and iron, will help maintain healthy growth and vibrant colors.
