Aquarium plant from tissue culture in closed cup.

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. As a traditional floating plant it offers good protection for young fish.

闭杯组织培养的水族植物。

日本天野隆 (Takashi Amano) 启发许多水族馆业主将 1-5 厘米高的世界性地钱 (Riccia Fluitans) 浸泡在水中。可以用一根钓鱼线把它绑在石头上来抑制它，但新芽总是向表面生长，所以可能需要用剪刀修剪它。添加 CO2 后，Riccia Fluitans 生长得最好，在良好的生长条件下，叶尖上会形成小氧气泡。作为传统的漂浮植物，它为幼鱼提供了良好的保护。
