Additional Information
Here is an excellent and attractive addition to any freshwater tank. The Marimo ball, also known as Moss ball or Japanese moss ball is actually a filamentous green algae (Chlorophyta) found in a number of lakes in the northern hemisphere: Japan, United Kingdom, Russia, Iceland and Northern Europe.
In its natural habitat, the Marino ball is moved around by undercurrents and sink or rise in order to receive plenty of light to carry out photosynthesis.
It ranks among the strangest plant on Earth and has been granted the status of National Treasure in Japan. In Iceland it is believed that taking good care of the plant will “make your wishes come true”.
Domestic Marimo can be grown in tap water at room temperature and be given small amounts of liquid fertilizer with half water changes on a weekly basis. The amount of light it needs varies from source to source. Some places say this plant needs high light while others say it requires little more than ambient light.
They "reproduce" when a bump forms on a Marimo and it falls off and gets pushed around until it forms the round shape. If you don't want to wait for that you can tear it apart. You can clean your Marimo by dipping it in water and gently squeezing like you would a dirty sponge.
Marimos balls develop their characteristically round shape because water currents push them around the bottom of lake beds. This algae is free floating so you don’t need a substrat in your tank. As it is photosynthetic, it will float or sink in response to light. The oxygen they produce makes them lighter so they rise to the top. To make them sink again, just squeeze the air out.
Marimos are mistakenly referred to as “moss balls” but they’re really a species of filamentous algae. If you’re looking for a fun “plant” to add to your indoor garden collection I highly recommend buying and growing a Marimo. They’re interesting little creatures that may not do much at first glance, but once you’ve had one around for a while you’ll see that it is very much a living thing. Sometimes Marimos floats and even in a cramped aquarium its moves around, either inching towards the light from the windows during cloudy days, or away from the light on very bright days.
Some aquarist have created quite unique landscapes using Marimos balls attached on wood or as a substrate cover. An easy way to do this is to open them up with your fingers and attach them to whatever you want with fishing line. They can be attached to small rocks to cover the substrate or they can be attached to roots. Just use your imagination.
