Green Myrio

About the Green Myrio

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.

1. Light requirements: Thrives under moderate to high lighting. Higher light levels promote denser growth and prevent the lower stems from losing leaves.

2. 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.

3. 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.

4. 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.

5. 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.

6. Propagation:

   • Propagates easily through stem cuttings. Cut healthy stems and replant them in the substrate, where they will develop roots.

7. 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.
