Riccia fluitans

Info

Crystalwort is well-documented around the world, and floats on the surface or inhabits moist substrate. Takashi Amano was the first to popularise this floating moss as an aquarium plant. He adds Riccia as a foreground plant to many of his designs. Cultivation and care are both easy: attach the cushions to rocks or logs to provide a solid base for them to grow on. Maintain compact growth by trimming the light green branches with scissors every so often. CO2 supplementation significantly increases growth.
