A set of two 3 cm Marimo moss balls — naturally occurring spherical colonies of Aegagropila linnaei algae (also sold as Chladoflora) with a dense, velvety dark green surface. The 3 cm size is compact enough for nano aquariums and shrimp tanks, and the pair can be placed together as a small natural grouping or separated to different areas of the layout for a more scattered, naturalistic effect.Marimo is one of the most genuinely low-maintenance species available. It grows in low light without CO2 injection and tolerates a wide range of temperatures and water conditions. Shrimp actively graze on the surface biofilm and are naturally attracted to these balls. Roll them gently between the palms at each water change to maintain their spherical shape and ensure even light exposure.Simply rinse and place in the aquarium — no planting or attachment needed. They sit naturally on the substrate. Suit aquariums from 10 litres upward. If they float after transit, a gentle squeeze underwater releases trapped air and they will sink to the substrate.
