Salvinia cucullata is a unique, free-floating aquatic fern prized for its tightly folded, cup-shaped leaves and soft, velvety texture. Native to Southeast Asia, this compact floating plant adds rich surface coverage, natural shading, and visual contrast to aquariums, ponds, and paludariums.
Its small, clustered leaves form dense, overlapping rosettes that create a sculpted, almost quilted appearance across the water’s surface. Unlike larger floating plants, Salvinia cucullata remains relatively manageable, making it ideal for nano tanks and controlled aquascapes. It also provides excellent refuge for fry, shrimp, and surface-dwelling fish while helping reduce excess nutrients in the water.
Perfect for aquarists seeking a natural, low-maintenance floating plant with distinctive texture and fast growth.

Care & Growing Conditions
Salvinia cucullata is easy to grow and adapts well to a variety of freshwater environments.
-
Lighting: Moderate light promotes tighter, more compact growth
-
Water Temperature: 68–82°F
-
pH Range: 6.5–7.5
-
Water Flow: Prefers calm or slow-moving water
-
CO₂: Not required
-
Propagation: Division; spreads naturally by fragmentation
Under high humidity and strong lighting, leaves become more cupped and densely layered. Lower light may result in flatter leaf growth.
Ideal Uses
-
Surface cover in planted aquariums
-
Nutrient export in shrimp tanks
-
Shade for bettas and labyrinth fish
-
Natural filtration support in ponds
-
Decorative accent in aquascapes
