Riccia fluitans - Iconic Floating Moss for Vibrant Aquascapes

Riccia fluitans aquarium plant, commonly known as Floating Crystalwort, is a versatile aquarium liverwort that can be grown floating on the surface or carpeted along the substrate. With its vibrant green, moss-like texture, it’s especially popular in Nature-style and Iwagumi aquascapes.

Originally discovered and popularised by Takashi Amano, Riccia is ideal for creating dense, bright green cushions, whether attached to rock, wood, or mesh. When grown with CO₂ injection, high light, and fertilisation, it develops bubbly pearling that adds life and movement to your layout.

Floating, it offers shade and biofilm for shrimp tanks and fry tanks, while as a carpet it requires regular trimming to prevent it from lifting and floating away.

Riccia is suitable for intermediate hobbyists, especially those using pressurised CO₂ systems, and is ideal for highlighting hardscape or foreground space with vibrant green colour and fine texture.

Tips for Aquascapers: Secure Riccia to rocks or driftwood with thread or mesh for a natural, stable arrangement. Regular trimming keeps the moss compact and encourages healthy growth.
