Aegagropila linnaei, known as Marimo, literally " a ball of seaweed" in Japanese and as Cladophora ball, Lake ball, or Moss Balls in English, is a species of filamentous green algae (Chlorophyta) found in a number of lakes in the northern hemisphere. A marimo is a rare growth form of the species where the algae grow into large green balls with a velvety appearance. Colonies of such balls are only known to form in Iceland, Scotland, Japan and Estonia.
There are three growth forms. One is epilithic (growing on rocks) and is usually found on the shaded side of the rocks. Another growth form lives as free-floating filaments, as small tufts of unattached filaments that frequently form a carpet on the muddy lake bottom. The third growth form is the lake ball proper, where the algae grow into sizable balls of densely packed algal filaments that radiate from the center. The balls do not have a kernel of any sort
Domestic marimo grow in tap water at room temperature as long as the water is changed every one or two weeks (more frequently in summer and less often in winter). The marimo can be placed in the refrigerator in hot weather (above 25°C), but does not survive freezing.
Photosynthesis occurs in normal household lighting, otherwise, indirect sunlight since the marimo is adapted for low light conditions only. Marimo balls can be immersed in club soda water to increase the rate of photosynthesis. The elevated carbon dioxide favours algae growth but may be detrimental to fish and other aquatic creatures. If the marimo green color turns brownish it may recover without intervention, otherwise a minimal amount of salt can be added as a suggested remedy.
Marimo are a great addition to cold & tropical freshwater Aquariums
