The Aegagropila linnaei, commonly known as the Marimo Moss Ball, is a fascinating and unique addition to aquariums and terrariums. Unlike most plants, these moss balls are not true moss but a form of filamentous green algae that naturally form into soft, velvety spheres. They are beloved for their charm, simplicity, and ease of care, making them a perfect choice for aquarists of all experience levels.
Key Features:
-
Spherical Green Algae: Marimo Moss Balls are naturally spherical and have a velvety texture, adding a playful and eye-catching accent to aquascapes. Their appearance can add a touch of whimsy and interest to any aquarium setup.
-
Low Maintenance: Ideal for beginners, Marimo Moss Balls require minimal care and thrive in a wide range of lighting and water conditions. They’re perfect for low-tech setups.
-
Aquascaping Accent: Versatile in placement, Marimo Moss Balls can be arranged as standalone decorations on the substrate or grouped to create a lush, aquatic “garden” look in the foreground.
-
Shrimp and Fish-Friendly: The soft texture provides shelter and enrichment for shrimp and small fish. Additionally, Marimo Moss Balls can help improve water quality by absorbing excess nutrients.
Care Requirements:
-
Lighting: Marimo Moss Balls thrive under low to medium light. While bright lighting can encourage faster growth, too much direct light may cause yellowing. Indirect or gentle light is ideal for their well-being.
-
CO₂: CO₂ supplementation is unnecessary, making Marimo Moss Balls suitable for low-tech aquariums.
-
Water Parameters: Adaptable to a wide range of conditions, they prefer slightly acidic to neutral water (pH 6.0-8.0) and temperatures between 18-28°C. They generally do better in cooler temperatures.
-
Cleaning: To keep them healthy, gently clean them occasionally. Remove the moss balls from the aquarium, rinse them in tank water, and roll them gently between your hands to maintain their shape.
Planting Tips:
- Simply place Marimo Moss Balls on the substrate or any flat surface in your tank. They do not need to be attached to hardscape.
- Rotate them occasionally to ensure even exposure to light and maintain their round shape.
- Marimo Moss Balls are highly compatible with most freshwater fish and shrimp and are resistant to nibbling, making them a durable and safe addition to your aquatic environment.
