Riccia Verde
Riccia fluitans var. fluitans
herbRiccia Verde is a bright green, delicate aquatic liverwort prized in aquascaping for its feathery, branching appearance. It floats freely in water or can be attached to hardscape to create lush, moss-like carpets. This low-maintenance plant is excellent for planted aquariums and paludaria.

Growing Conditions
Soil
Growth Stages
Propagule/Fragment
1-2 weeksIndividual tiny branching fronds begin absorbing nutrients from water column
Ensure gentle water movement to distribute nutrients evenly. Maintain consistent lighting and water parameters.
Establishment
2-4 weeksFronds extend and multiply; plant begins to form loose clusters if floating, or anchors to hardscape
Start fertilizing if not already dosed. Ensure CO2 and macronutrient levels are adequate. Check for algae overgrowth.
Vegetative Growth
4-8 weeks onwardDense branching occurs; plant spreads laterally across substrate or hardscape; bright green color deepens
Prune excess growth to maintain desired shape and prevent shading of lower layers. Increase nutrient dosing if needed.
Maintenance/Maturity
OngoingPlant reaches desired density and coverage; growth rate stabilizes with regular care
Perform regular pruning and thinning to maintain aesthetics and health. Continue routine fertilization and water changes.
Propagation
As neededExcess biomass can be harvested and replanted in new areas or aquariums
Gently separate frond clusters by hand or with tweezers. Replant or float fragments to establish new patches.

Common Pests
-
Reduce light duration, increase water changes, boost CO2/nutrient dosing to favor plant growth over algae. Add algae-eating fish (Otocinclus, Amano shrimp).
-
Manual removal with toothbrush or thread. Reduce phosphate; increase magnesium. SAE (Siamese Algae Eaters) or Amano shrimp effective.
-
Remove decaying organic matter. Increase water flow and oxygen. Use hydrogen peroxide spot treatment or planaria-specific traps; avoid copper-based treatments.
-
Remove excess snails manually. Reduce feeding to starving population. Add snail-eating fish if appropriate for aquarium.
Uses
Aquatic Landscaping & Aquascaping
HouseholdRiccia Verde creates stunning naturalistic underwater landscapes with its feathery, branching structure. It can be grown as a floating plant, carpeting substrate, or attached to rocks and driftwood for creative scaping designs. [source]
Fish Habitat & Fry Nursery
WildlifeDense Riccia Verde provides shelter and grazing surfaces for small fish, shrimp, and fry. The intricate fronds offer hiding places and biofilm growth for newborn aquatic creatures. [source]
Ornamental Aquatic Plant (Non-Edible)
CulinaryWhile technically not for consumption, Riccia Verde is sometimes researched for its potential as a biofuel and oxygen-producing organism in experimental bioengineering and closed-loop aquatic systems. [source]
Water Quality Bioremediator
MedicinalRiccia Verde absorbs excess nutrients (nitrogen, phosphorus) from aquarium water, helping to reduce algae blooms and maintain stable water chemistry. This natural bioremediating function supports overall ecosystem health. [source]
Nano & Artistic Aquarium Design
CraftValued by aquascapers for creating intricate carpet effects and artistic formations in nano tanks and planted aquariums. Its delicate appearance adds visual depth and complexity to underwater designs. [source]

Harvest Tips
Riccia Verde is not harvested for consumption but propagated by gently separating healthy frond clusters with tweezers or by hand. Trim excess growth to maintain desired density and shape. Harvested fragments can be floated or reattached to hardscape. Remove dead or yellowing fronds regularly to maintain plant health and prevent decay.
Fun Facts
- 🌱 Riccia fluitans is one of the few truly aquatic liverworts and is not a true moss, despite its moss-like appearance. It lacks roots and absorbs nutrients directly through its fronds.
- 🌱 Riccia Verde can double or triple in mass within weeks under optimal lighting and nutrient conditions, making it one of the fastest-growing aquatic plants available.
- 🌱 In nature, Riccia fluitans is found in slow-moving streams and stagnant waters across tropical and subtropical regions worldwide, where it plays a role in carbon cycling and providing microhabitat for aquatic invertebrates.
