Myrio Green (Myriophyllum pinnatum) – Lush, Fine-Leaf Background Plant for Planted Aquariums
Myrio Green, also known as Myriophyllum pinnatum, is a vibrant, fast-growing stem plant prized for its delicate, feathery foliage. Its bright green, finely divided leaves create a soft, flowing texture in the aquarium, making it an excellent background or midground filler for aquascapes.
This plant thrives in nutrient-rich conditions and grows quickly, helping absorb excess nutrients and improving water quality. With strong lighting and CO₂ supplementation, it becomes even fuller and more vibrant. Myrio Green is ideal for breeding tanks as its dense growth offers shelter for fry and shrimp.
