I recently discovered Marimo Moss Balls. It is not actually moss it is algae. Marimos originatee in the lakes of Japan and Iceland.
I have 4 moss balls, mine are very young but, with proper care they can live up to 200 years old!
Marimo Moss balls can be burnt and then they will die. They can burn because of too much sunlight and they can die because their water is too hot. In summer I put an ice cube in their tank to keep them nice and cool.
