Frequently Asked Questions (FAQs)

1. Are Marimo balls good for aquarium?

A Marimo Moss Ball is an interesting addition to a tank. They add green color to the setting and can draw small amounts of nutrients from the water that would otherwise feed less desirable forms of algae. Along these lines, some hobbyists suggest that they help remove small amounts of Nitrate from the water as well.

2. Is a moss ball a live plant?

They're green. They're cute. And they're alive, but they don't act like it! A bit of a misnomer, marimo moss balls are actually not moss at all but a colony of freshwater algae.

3. Do moss balls grow in fish tanks?

Marimo balls grow slowly: up to 5 mm per year, eventually reaching 2 to 5 inches in aquariums, or 8 to 12 inches in natural conditions. Wild marimos live in cold, dark waters where the waves slowly turn them to expose all sides to the light. Indoors they need to be kept in clean, cold water with low lighting.

4. How long do Marimo moss balls live?

Marimo balls are regarded as good luck charms in Japan, and since they have been known to live to 200 years or longer, they are often kept as family heirlooms.
