Green Myrio (Myriophyllum pinnatum) is a fast-growing, feathery aquatic plant that adds a soft, flowing texture to freshwater aquariums. It is commonly used as a background plant or for providing shelter for small fish and shrimp. Its vibrant green color and fine leaves make it a visually appealing choice for planted tanks. Light requirements: Thrives under moderate to high lighting. Higher light levels promote denser growth and prevent the lower stems from losing leaves. Water parameters: Temperature: Prefers a range of 68 to 82°F (20 to 28°C). pH level: Best suited for slightly acidic to neutral water, with a pH range of 6.0 to 7.5. Hardness: Adaptable to soft to moderately hard water. Substrate and placement: Can be planted in the substrate or left floating. If planted, anchor the stems in fine-grain substrate to prevent them from floating up. Ideal for background placement due to its tall, bushy growth. Nutrients and CO2: Fertilization: Benefits from regular liquid fertilization, particularly with iron and micronutrients, to maintain healthy growth. CO2 supplementation: Not required but can enhance growth rate and overall plant health. Pruning and maintenance: Grows quickly and requires regular trimming to prevent overgrowth. Pruning encourages bushier growth and prevents lower stems from becoming bare. Remove any decaying leaves to maintain water quality. Propagation: Propagates easily through stem cuttings. Cut healthy stems and replant them in the substrate, where they will develop roots. Special considerations: Can be sensitive to algae if lighting and nutrients are not well-balanced. Provides excellent cover for fry and shrimp, making it a great addition to breeding tanks. May be eaten by herbivorous fish, so caution is advised when keeping it with plant-eating species. With proper lighting, nutrients, and trimming, Green Myrio can create a lush, natural backdrop in an aquarium while also improving water quality by absorbing excess nutrients.
