Description
A rootless liverwort. Originally floating, but in Takashi Amano's style it's tied to stones with mesh to form an emerald underwater 'lawn'.
Care
To keep it on the bottom, tie it to a flat stone with nylon mesh. Without bright light and CO₂ it floats up.

- Привязать тонкой леской или нейлоновой сеткой к плоскому камню. Через 2–3 недели риччия сама прирастёт.
