Today I though I would share with you my family of Marimo! Cladophora aegagropila, or marimo, are spherical shaped filament algae bits that thrive at the bottom of chilly lakes. The shape is cause by the current in the water, rolling them into a ball over time. The slow growing algae can be found in only a few lakes in Japan and Iceland. Marimo enjoy shade and cool water, similar to how life would have been in their natural environment. Their water needs to be changed about once a week, but other than that they are very simple pets!
