Marimo Ball Moss – branched, 5–7 cm

This single moss ball is a live aquatic plant for aquarists who want a low-maintenance decorative element. Its low light and CO2 requirements and very slow growth make it a practical choice for tanks where demanding plants are not an option.

Why it matters

• Low lighting demand: the plant is rated for approximately 0.35 W per litre, so it can be kept under modest lighting.
• Low CO2 requirement: it is listed for 4–7 mg/l, and the supplier states that no CO2 or fertiliser dosing is needed.
• Easy propagation: the supplier describes splitting the ball into smaller pieces, with added NO3 and PO4, as the method for multiplying the balls.
• Flexible form: the moss can be torn apart, arranged into a carpet, or tied to roots, which gives options for layout.

What it works with

The ball suits planted freshwater aquariums, garden ponds and paludariums, and its small size fits tanks where space for foreground plants is limited. Because it grows slowly and needs little light and CO2, it can share a tank with other low-demand plants and does not require a dedicated dosing setup.
