A marimo ball is a rare growth form of algae, which grows into large green balls with a soft, velvety appearance.they are native to japan where they naturally grow at Lake Akan. They are also found in Iceland ,Estonia and scotland. They can grow patches on a lake floor at depths from 2 to 2.5 m. The round shape of the marimo is maintained by wave action that turns it. In Japan the marimo has said to be a national treasure. They where named by the Japanese botanist “Tatsuhiko Kawakami”. Mari means bouncy ball and Mo is a term for plants that grow in water. So , marimo means bouncy plant.People often mistake them for living animals because they are usually moving around in the tank.
The Moss Ball is a spongy velvet-like green algae ball that in the wild is found around Japan and Northern Europe. They were once thought to be extremely slow growing, but recent studies suggest that the growth can be accelerated by providing more nutrients. In its natural habitat, they are moved around by undercurrents and sink or rise in order to receive plenty of light to carry out photosynthesis.
The Moss Ball requires moderate to high lighting, approximately 3 watts per gallon provided by full spectrum (5000-7000K) bulbs. The temperature of the water should be between 72°-82°F, with an alkalinity of 3-8 dKH and a neutral pH.
The Moss Ball propagates by division. It starts with a division line which progresses to the splitting off of a smaller new Moss Ball.
