Overview
Ricciocarpos natans is a small liverwort that floats freely on the water surface. Its body is about 1 cm long, heart- or fan-shaped, grooved down the middle and dark green. Purple, tassel-like scales hang into the water from its underside; this appearance sets it apart from other floating plants. Although it belongs to the same family as Riccia, it is larger and grows more slowly. In the wild it is found in still lakes, ponds and ditches.
Planting and Placement
It is not planted; it is placed on the surface. A calm, unrippled surface is ideal.
Care and Fertilization
- Light: Moderate.
- CO₂: Not required.
- Surface: Strong surface flow and splashing water cause it to flip over.
- Its bodies reproduce by forking and splitting in two. Remove the excess with a net; do not throw it into natural waters.
