General Description
Myriophyllum tuberculatum, commonly known as red watermilfoil, is a vibrant aquatic plant native to slow-flowing and stagnant waters in the Asian tropics. It is often confused with a similar reddish-brown milfoil native to Florida. This species requires intense lighting, CO2 injection, and specific nutrient levels for optimal growth, with a propensity to develop rusty red-colored leaves up to 10 cm in diameter under favorable conditions.
Aquarium Suitability
Suitable for aquariums, M. tuberculatum is a challenging plant to cultivate, demanding a minimum light requirement of 0.8 watts per liter and CO2 supplementation. It thrives with nitrates and phosphates maintained at levels of 5-15 mg/l and 1-2 mg/l, respectively, to avoid stunted growth. This plant benefits from an iron-rich environment and trace nutrients for healthy development, making it a striking addition for aquarists striving to add vibrant color accents to their setups.
Demands and Hardiness
Considered a difficult species to grow, M. tuberculatum requires meticulous care to thrive in aquarium settings. Regular maintenance of nutrient levels and adequate lighting is essential to prevent nutrient deficiencies that can hinder plant growth. Propagation through lateral shoot cuttings is recommended to ensure a steady growth pattern, making it a valuable addition for aquarists seeking a unique and visually appealing aquatic display.
Aquascaping & Usage
With its fine-leaved structure and intense coloration, M. tuberculatum serves as an ideal plant for adding colorful accents to aquascapes, background arrangements, midground plantings, and Dutch-style street layouts. Its striking appearance and moderate size make it suitable for smaller planted tanks, creating visually captivating focal points within the aquarium environment.
Propagation
Propagation of Myriophyllum tuberculatum is best achieved through the cutting and replanting of lateral shoots into the substrate. This method allows for continued growth and expansion of the plant, ensuring a healthy and vibrant presence within the aquatic habitat. Regular maintenance and pruning are essential to promote lateral shoot development and maintain the plant's bushy habit and visual appeal.
Habitat and Distribution
This species is found in regions such as India, Pakistan, China (Guangdong), Malaysia, Indonesia, and Australia, where it thrives in slow-flowing and stagnant waters. In Europe, M. tuberculatum is readily available in trade, while its presence in the US is less widespread. Despite being a challenging plant to cultivate, its unique aesthetic qualities and striking appearance make it a sought-after choice for aquarists looking to enhance their aquatic environments with vibrant color and distinctive foliage.
