Duckweed (Lemna minor)
Duckweed is a tiny aquatic plant that offers incredible benefits for freshwater aquariums, shrimp tanks, and outdoor ponds. Known for its rapid growth, easy care, and natural filtration ability, duckweed is ideal for aquarists seeking a low-maintenance plant that improves water quality while providing surface cover.
With its small, bright green leaves and trailing roots, duckweed spreads quickly across the surface of the water, creating a shaded, natural canopy that helps reduce algae growth by limiting light penetration. It’s an excellent choice for tanks housing small fish, shrimp, or fry, offering both shelter and a supplemental food source.
Why Choose Duckweed?
- Provides natural water filtration by absorbing excess nutrients
- Spreads quickly to cover water surface, reducing light for algae growth
- Offers shelter and hiding spots for small fish and shrimp
- Acts as a supplemental food source for aquatic creatures

I added duckweed to my 10-gallon shrimp tank and it spread quickly. The water looks clearer now, and my shrimp have more hiding spots. Easy to maintain and no special care needed.

Perfect for my outdoor pond. It spreads naturally and helps shade the water. My fish seem more active and the water is cleaner.

It grew fast at first, but I had to trim it occasionally to prevent overgrowth. Still, it’s a good option for beginners.
