🌿 Overview

Salvinia is a floating aquatic fern known for its small, fuzzy, oval-shaped leaves that rest on the water surface. It is widely used in aquariums to create shade, reduce algae growth, and provide shelter for fry and shrimp.

This plant is highly beginner-friendly, adaptable to a wide range of water conditions, and requires minimal care. While CO₂ and fertilizers are optional, nutrient-rich water enhances faster growth.

🍃 Appearance

• Small, bright green oval leaves with fine hairs on the surface
• Forms dense floating mats across the water surface
• Provides a soft, natural look to aquariums
• Ideal for shading sensitive plants and creating hiding spaces for fish and shrimp
• Can cover large areas quickly under optimal conditions

🌿 Plant Type (Hard/Soft)

• Type: Floating fern
• Category: Soft aquatic plant
• Growth rate: Fast; rapid mat formation under good light

🌡️ Ideal Water Temperature

• 20°C – 30°C (68°F – 86°F)
• Prefers tropical freshwater conditions

💡 Lighting Conditions

• Moderate to high lighting recommended
• Moderate light supports healthy growth; high light accelerates mat formation

• Benefits from liquid fertilizers for faster growth
• Provides shade and reduces algae growth in open tanks
• Requires occasional thinning to prevent overcrowding
• Prefers clean, nutrient-rich water

🌱 Propagation

• Propagates via natural fragmentation
• Leaves produce small runners that form new plants
• Can be easily divided and spread across the aquarium surface
