The Marimo moss ball is a rare algae ball. Its scientific name is Aegagropila linnaei. These algae balls form in freshwater lakes in northern Europe, Japan, Iceland, and New Zealand. They are made of a type of green algae called Cladophora, which roll up into ball shapes. There are two main types of Marimo moss balls.
Marimo moss balls from nature
Natural Marimo moss balls grow in large lakes. They get water currents and waves to form their shape. These Marimo are usually bigger than the pet ones. Some can be as big as a basketball. The natural ones have a loose structure and a bright green color. They are delicate and need specific water conditions. They can live for a long time.
Farmed Marimo moss balls
Farmed Marimo moss balls are created through aquaculture. They roll the algae by hand to make them into a ball shape. These balls are usually smaller and more compact than the natural ones. They are easier to take care of and do not need as strict water conditions. Farmed Marimo are popular as pets in aquariums and terrariums. They are less likely to die than natural ones.
Shape and Size:
Marimo balls are bright green, fuzzy moss-like plants. They form into tight, smooth spheres, usually 5 to 8 centimeters wide. Some can get as big as 14 inches over many years. Their round shape comes from waves rolling them over in water, making them compact.
Color and Texture:
Marimo have a vibrant green color due to chlorophyll in the algae. This green can fade if the water quality is poor or the light is too bright. The texture is soft and fuzzy because of the dense algae strands that wrap around each other.
Habitat Requirements:
Marimo thrive in cool, freshwater lakes with little current. They prefer temperatures between 60 and 70 degrees Fahrenheit.
