Green Myrio Plant

Green Myrio (Myriophyllum sp.)

Appearance & Growth

Bring soft texture and fresh green color to your aquarium with Green Myrio. Its finely divided, feathery foliage creates a delicate contrast to broad-leaved plants and driftwood. As the stems fill out, they form a lush backdrop where small fish can weave between the leaves and shrimp can explore for biofilm.

Size & Placement

A tall-growing stem plant best suited to the background of most aquariums or the midground of larger layouts. Stems can grow to the water surface, so regular trimming helps maintain your preferred height and prevents shading of plants below.

Compatible Tankmates

• Small, peaceful community fish such as tetras, rasboras, and corydoras
• Dwarf shrimp, which use the fine foliage as grazing surfaces and cover
• Plant-safe snails such as nerites
• Avoid: plant-eating fish and vigorous diggers that may damage delicate leaves or uproot stems

Planted-Tank Role

Green Myrio adds height, movement, and fine-leaved shelter to freshwater aquascapes. Growing stems take up nutrients from the aquarium, while dense foliage provides cover for fry and small invertebrates. Gentle water circulation helps keep debris from collecting among the leaves. Plants support a balanced aquarium but do not replace filtration or regular water changes.

Lighting & Nutrition

• Lighting: moderate to bright aquarium lighting encourages fuller growth. Insufficient light can lead to sparse stems and loss of lower leaves.
• Photoperiod: start with 6–8 hours daily and adjust to plant response and algae growth.
• Fertilizer: provide a complete aquarium plant fertilizer according to its label, adjusting dosing to your setup.
• CO2: supplemental CO2 can encourage denser, more vigorous growth; results without injection depend on lighting and available nutrients.

Water Conditions

• Best suited to stable freshwater aquarium conditions with gentle circulation.
• Avoid abrupt changes in temperature or water chemistry.
• Keep foliage free of accumulated debris and remove damaged or decaying growth promptly.
• Green Myrio is a trade name used for more than one Myriophyllum species; precise temperature, pH, and hardness preferences depend on the variety supplied.

Planting Guidance

• Remove any bunching weights, bands, or packing material before planting, and gently rinse the stems.
• Separate the stems and remove leaves from the portion that will sit beneath the substrate.
• Plant stems individually with space between them so light and water can reach the lower foliage.
• Handle gently to avoid crushing the stems or damaging the fine leaves.
• Position away from strong filter outlets that could batter the foliage.

Trimming & Propagation

• Trim stems above a leaf node to maintain height and encourage branching.
• Replant healthy top cuttings after removing the lowest leaves.
• Thin crowded groups periodically to keep the lower stems from becoming shaded.
• Some older foliage may decline as the plant adjusts to a new aquarium. Remove deteriorating sections and watch for healthy new growth.
