Duckweed (Lemna spp.) is one of the smallest and fastest-growing floating plants in the aquarium hobby. Its tiny green leaves spread across the water's surface, creating natural cover while pulling nutrients directly from the water column.
It's particularly useful in shrimp tanks, breeding setups, and aquariums where nutrient uptake is a priority. The dense surface growth and dangling roots provide additional grazing area for shrimp and microorganisms while giving fry a little extra cover.
Duckweed is also extremely easy to grow. In the right conditions, a small amount can turn into a substantial colony surprisingly quickly.
Care Information
Scientific Name:Lemna spp.
Plant Type: Floating
Growth Rate: Very Fast
Lighting: Low to High
CO₂: Not Required
Temperature: Approximately 65–82°F
pH: Approximately 6.0–8.0
Difficulty: Very Easy
Placement: Water Surface
Propagation: Natural division
Best For: Shrimp tanks, breeding tanks, fry grow-out tanks, low-tech aquariums, and setups where fast-growing floating plants are wanted.
Duckweed requires very little special care beyond adequate light and nutrients. Because it reproduces so quickly, regular thinning is usually necessary to prevent it from completely covering the surface and reducing light to plants below.
It's worth knowing exactly what you're getting into: Duckweed is extremely persistent. Once introduced to an aquarium, completely removing it can be difficult. For aquarists who want fast-growing surface coverage, that's one of its greatest strengths. For those who don't, another floater may be a better choice.
The Reserved Aquatics Standard
Duckweed certainly isn't rare, and we're not going to pretend it is. What matters here is receiving healthy, actively growing plants that can establish quickly in your aquarium.
Simple, useful, and exceptionally good at what it does.
Quality Worth Keeping.
