Myriophyllum guyana, also known as Guyana Foxtail, Fine Leaf Myrio, or Guyana Myriophyllum, is a graceful aquatic stem plant ideal for planted aquariums and aquascapes.
Its fine, feather-like leaves create lush green density and add a flowing, natural movement to the tank — especially in gentle current.
This species is hardy and moderately fast-growing, suitable for both beginners and advanced aquascapers who want a soft, textured background plant.
