🌿 Overview

Limnobium laevigatum is a soft, floating freshwater plant native to tropical regions. Its rounded, bright green leaves float on the water surface, while long, feathery roots dangle beneath, creating a natural habitat for fry and shrimp.

Highly adaptable, Frogbit is beginner-friendly and grows without CO₂, although supplemental CO₂ and nutrient-rich water promote faster growth and denser mat formation. It is perfect for aquascaping, aquaponics, and natural-looking aquariums.

🍃 Appearance

• Rounded, lily-like floating leaves, 2–5 cm in diameter
• Long, feathery roots hanging under the water
• Forms dense floating mats, providing shade and hiding spots
• Bright green with soft, velvety leaf texture
• Adds tropical, natural aesthetics to any aquarium

🌿 Plant Type (Hard/Soft)

• Type: Floating aquatic plant
• Category: Soft plant
• Growth rate: Fast under moderate to high light

🌡️ Ideal Water Temperature

• 20°C – 28°C (68°F – 82°F)
• Thrives in tropical freshwater aquariums

💡 Lighting Conditions

• Moderate to high lighting recommended
• Moderate light supports healthy growth; high light encourages denser mats and vibrant leaves
• Low light slows growth and leaf size

🌿 CO₂ Requirement

• Not required
• CO₂ optional to enhance faster, denser growth
• Ideal for low-tech and beginner 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 optimal growth
• Provides shade for sensitive plants and reduces algae
• Requires occasional thinning to prevent overcrowding
• Sensitive to strong water currents; best in calm, still water

🌱 Propagation

• Propagates via natural offsets (daughter plants)
• Fast-spreading; dense mats form from multiple offsets
• Easy to move and plant in other areas of the tank

💡 Do You Know?

Limnobium laevigatum is widely used in aquascaping and aquaponics because it absorbs excess nutrients, provides shelter for fry and shrimp, and reduces light penetration, helping prevent algae growth. Its dangling roots also support small aquatic life and improve water aesthetics.
