Marimo moss balls - Chladoflora (2cm) Set of 3

Three 2cm Marimo balls — tiny, perfect for nano and shrimp tanks

    Description

    A set of three 2 cm Marimo moss balls — tiny, naturally occurring spherical colonies of Aegagropila linnaei algae with a dense, velvety dark green surface. The 2 cm size is ideal for nano aquariums and shrimp tanks where space is limited and proportion matters. The set of three provides a small natural grouping that can be arranged between rocks and wood in detailed aquascape foregrounds.

    Marimo is one of the most genuinely low-maintenance species available. It grows in low light without CO2 injection and tolerates a very wide range of temperatures and water conditions. Shrimp actively graze on the surface biofilm. Roll them gently between the palms at each water change to maintain their spherical shape and ensure even light exposure on all sides.

    Simply rinse and place in the aquarium — no planting or attachment needed. They sit naturally on the substrate. Suited to aquariums from 10 litres upward and particularly effective in nano set-ups and shrimp tanks where the small size adds planted foreground detail without taking up significant space. If they float, a gentle squeeze underwater releases any trapped air.

    Healthy moss balls, however a lot smaller than I anticipated but that was my interpretation, sizing on website is accurate.

    Review

    Delivery was fast, but the person who packed them didn't close the seal on the plastic bag, so they turned up bone dry. I let them rehydrate for a few days so I could then clean them and add in them with my other Marimo balls (bought elsewhere), and was so shocked to find how unbelievably filthy they were. The water I cleaned them in was dark brown by the time I'd finished. I will absolutely not be putting them anywhere near my other Marimo balls. They have brown patches, which is a symptom of not enough light. They also don't hold a spherical shape, so clearly haven't been moulded often enough whilst being grown. I guess for the price I'm not sure why I expected decent Marimo balls...

    Giving 4star rather than 5 only because I had to rinse them quite a few times and really it’s probably as they were on sand.Otherwise I am delighted with these moss balls so much so that I bought 3 more.My daughter is taking 3 of them for her house.

    Got what I ordered but I didn't realise how small they were. So I've ordered some bigger ones. Otherwise my catfish loves it so much that he tore some of it apart as soon as he spotted it haha! Arrived quickly. Second ever purchase from here!

    Common Questions

    How small is 2cm?

    Each ball is 2 cm in diameter — roughly the size of a large grape. The set of three makes an effective small grouping in nano tanks and shrimp set-ups.

    Do they need CO2 or special lighting?

    No — Marimo grows in low light without CO2 injection.

    They're floating — what do I do?

    A gentle squeeze underwater releases any trapped air and they will sink to the substrate.

    Are they safe for shrimp?

    Yes, fully. Shrimp graze on the surface biofilm constantly and are naturally attracted to Marimo.

    How do I keep them round?

    Roll them gently between your palms at each water change to maintain their spherical shape.
