Riccia fluitans, also known as floating crystalwort or floating liverwort, is a versatile and fast-growing freshwater aquarium plant prized by aquascapers, shrimp keepers, and planted tank enthusiasts. Naturally found in slow-moving rivers, ponds, and lakes around the world, Riccia fluitans forms lush, bright green mats that can float on the water’s surface or be attached to driftwood, rocks, or mesh to create stunning underwater carpets.
In the wild, Riccia fluitans thrives in calm, nutrient-rich waters across Europe, Asia, Africa, and the Americas. It naturally floats just below the surface, forming dense mats that provide cover for fry, shrimp, and small fish. In home aquariums, this plant grows quickly under good lighting, producing vibrant green fronds that add a natural, oxygen-rich habitat for aquarium inhabitants.
Lighting: Requires medium to high light for best growth and vivid green coloration.
Placement: Can be grown floating freely on the surface or attached to hardscape with thread or netting for a moss-like carpet effect.
CO₂ and Nutrients: Benefits greatly from CO₂ injection and regular liquid fertilization, especially when grown submerged.
Trimming & Maintenance: Regular trimming prevents overgrowth and keeps mats healthy, ensuring they don’t block too much light from reaching plants below.
Water Conditions: Adaptable to a wide range of freshwater aquarium parameters, making it suitable for community tanks, shrimp tanks, and aquascapes.
Provides shelter and spawning areas for fish fry and shrimp.
Naturally oxygenates water and improves aquarium health.
Perfect for nature-style aquascapes and Iwagumi layouts.
Easy to propagate—just divide mats and reattach or let them float freely.
