Salvinia Minima

Salvinia minima, commonly known as Water Spangles, is a compact, fast-growing floating fern prized for its small, oval leaves and soft, textured surface. Native to Central and South America, this hardy freshwater floater forms dense, bright green mats that enhance aquariums and ponds while naturally improving water quality.

Each node produces paired floating leaves with a slightly bumpy, water-repellent texture, giving the plant a velvety appearance. Beneath the surface, modified submerged leaves function like roots, absorbing nutrients directly from the water column. Its ability to quickly uptake excess nitrates makes it a powerful natural aid in algae control and overall tank balance.

Perfect for aquariums, shrimp tanks, breeding setups, and outdoor water gardens in warm climates.

Key Points

• Small, textured floating leaves with vibrant green color

• Rapid nutrient absorption to help control nitrates

• Provides excellent cover for fry and shrimp

• Reduces light intensity to limit algae growth

• Fast-growing and easy to propagate

• Ideal for nano tanks and larger aquariums alike

Care & Growing Conditions

Salvinia minima is beginner-friendly and adaptable to a range of freshwater setups.

• Lighting: Low to moderate lighting (moderate light promotes compact growth)

• Water Temperature: 65–82°F

• pH Range: 6.5–7.5

• Water Flow: Prefers calm or slow-moving water

• CO₂: Not required

• Propagation: Spreads naturally through fragmentation and branching

Avoid strong surface agitation, which can damage or sink the delicate leaves. Regular thinning helps prevent complete surface coverage and ensures adequate gas exchange.

Ideal Uses

• Surface cover for planted aquariums

• Shrimp and fry protection

• Betta tanks

• Nutrient export systems

• Outdoor ponds (in frost-free regions)

• Low-maintenance floating plant displays
