Self sustaining and adorable green balls of moss that create their own food to aid photosynthesis.
Light: Too much bright light can damage the marimos. Somewhere indirect but where brightness can reach, this may encourage them to photosynthesise which means they will release oxygen, making them move around in their water (very exciting when they do)
Water: They live in water - be sure to change the water every week or so. This may need to be increased during summer. When changing water very gently run water over the balls and use your hands to clean them to remove any excess dirt. They thrive when they're clean.
