Tropica Riccia fluitans 1-2-Grow!

Japanese Takashi Amano has inspired many aquarium owners to keep the 1-5 cm tall cosmopolitic liverwort, Riccia fluitans, submerged. It can be kept down by tying it to a stone with a piece of fishing line, but new shoots always grow towards the surface, so it may be necessary to prune it with scissors. Riccia fluitans thrives best with added CO2 and in good growing conditions small oxygen bubbles form on the leaf tips.

Care requirements: Difficulty: Medium (per Tropica). Light demand: Medium. CO2 demand: Medium; added CO2 is beneficial. Growth rate: Medium. Placement: Midground to background, tied to rocks or driftwood. Height in tank: 3-5+ cm. Aquarium plant from tissue culture in closed cup.
