Frogbit (Limnobium laevigatum) – Floating Aquarium Plant

Frogbit (Limnobium laevigatum) is a fast-growing floating plant widely appreciated for its decorative appearance and functional benefits. The plant features smooth, round leaves that float on the water surface, while its long, feathery roots hang below, creating a natural refuge for fish fry and shrimp.

Frogbit helps reduce excess nutrients, improve water quality, and limit algae growth by shading the aquarium. It adapts easily to a wide range of water conditions and is suitable for both beginner and experienced aquarists. Moderate surface water movement is recommended to prevent leaf damage.

This plant propagates quickly through runners, making it easy to maintain or share. Frogbit is completely shrimp-safe and fish-safe, making it ideal for community tanks, breeding setups, and natural-style aquariums.
