Alternanthera lilacina, commonly known as Purple Alternanthera, is a vibrant and attractive aquatic plant that adds a splash of purple color to aquariums. Here's some information about Alternanthera lilacina:
Appearance: Alternanthera lilacina features beautiful purple to reddish-purple leaves that can vary in intensity depending on lighting conditions. The leaves are elliptical or lanceolate in shape and grow in opposite pairs along the stem. The plant has a bushy growth habit, with stems reaching a height of 6-12 inches (15-30 cm) under ideal conditions.
Care Requirements: While Alternanthera lilacina is relatively easy to care for, it benefits from specific conditions to thrive. Here are some care guidelines:
Lighting: Medium to high lighting is recommended to maintain the intense purple coloration. Providing around 2-4 watts per gallon of light or using LED lights designed for plant growth will promote healthy growth and vibrant foliage.
Water Parameters: It prefers a temperature range of 72-82°F (22-28°C) and a slightly acidic to neutral pH level between 6.0 and 7.5. The water hardness can be moderate to soft.
Nutrients and Substrate: Alternanthera lilacina benefits from a nutrient-rich substrate. Using aquasoil or adding root tabs with essential nutrients like iron can promote healthy growth and vibrant colors. Additionally, supplementing with liquid fertilizers that contain micronutrients can further enhance growth and leaf coloration.
CO2 Injection: While not mandatory, providing a CO2 supplement can boost growth and color intensity. Carbon dioxide injection can be particularly beneficial in high-tech planted aquarium setups, where the demand for nutrients and CO2 is higher.
Pruning and Propagation: Regular pruning is necessary to maintain the desired shape and prevent the plant from becoming too bushy. Alternanthera lilacina can be propagated by taking stem cuttings and replanting them in the substrate.
Compatibility: Alternanthera lilacina is generally compatible with most freshwater fish and invertebrates. However, keep in mind that some herbivorous fish species may nibble on the leaves, so it's best to choose tankmates carefully.
With its stunning purple foliage, Alternanthera lilacina can serve as an eye-catching focal point or a vibrant accent in planted aquariums. Its color contrasts well with other green plants, creating an appealing visual display. By providing the right conditions and care, you can enjoy the beauty of Alternanthera lilacina in your aquatic setup.
