Riccia fluitans

Japanese Takashi Amano has inspired many aquarium owners to keep Riccia fluitans submerged. It can be kept down by tying it to a Riccia Stone with a piece of Riccia Line, but new shoots always grow towards the surface, so it may be necessary to prune it with scissors. Under water Riccia fluitans thrives best with added CO2 and in good growing conditions small oxygen bubbles form on the leaf tips. As a traditional floating plant offers good protection for young fish.
