Description
Overview: Riccia fluitans, or Crystalwort, was made famous by Takashi Amano, who first had the idea of tying it to stones to create a vibrant, bubbling "moss" carpet. Naturally a floating plant, it forms dense, bright green mats. When submerged and given high light and CO2, it produces massive amounts of oxygen bubbles. It is a fast grower and needs regular maintenance to keep it from detaching and floating to the surface.
