🌿 Overview

Salvinia cucullata is a soft, floating aquatic fern native to tropical and subtropical regions. It produces dense floating mats with small, fuzzy, oval leaves that enhance the natural look of aquariums.

Highly adaptable, it is beginner-friendly and can grow without CO₂, although high light and nutrient supplementation accelerate growth and increase mat density.

🍃 Appearance

• Small, bright green, oval-shaped leaves with fuzzy surfaces
• Forms dense mats on the water surface
• Height: Floats naturally; leaves ~1–2 cm wide
• Adds soft, flowing texture to aquascapes
• Provides shade for sensitive plants and hiding spaces for fry and shrimp

🌿 Plant Type (Hard/Soft)

• Type: Floating fern
• Category: Soft aquatic plant
• Growth rate: Fast; dense surface coverage 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
• Low light slows growth and may reduce leaf vibrancy

🌿 CO₂ Requirement

• Not required
• CO₂ is optional and can slightly enhance growth
• Ideal for low-tech aquariums

⚗️ Ideal pH Level

• pH: 6.0 – 7.5
• Slightly acidic to neutral water preferred

💧 Other Requirements

• Floating plant; no substrate needed
• Benefits from liquid fertilizers for faster growth and healthier leaves
• Provides shade and reduces algae growth in open tanks
• Requires occasional thinning to prevent overcrowding

🌱 Propagation

• Propagates via natural fragmentation
• Leaves produce new plants from runners
• Easy to spread across the water surface for dense coverage

💡 Do You Know?

Salvinia cucullata is popular in aquascaping and aquaponics because it creates natural floating surfaces, reduces light to slow algae growth, and provides shelter for fry and shrimp. Its dense mats also help maintain water quality by absorbing nutrients from the water column.
