One sandwich filled to a half inch thickness. Should cover the top of a 28 or 20L tank. Great food source for goldfish and other plant eating fish.

Duckweed (Lemna minor) is a tiny, fast-growing floating aquatic plant ideal for ponds and aquariums, offering excellent natural filtration, shade, and a high-protein food source for fish. It thrives in full sun, easily covering water surfaces in dense, bright green mats that reduce algae growth, but it requires regular management to prevent rapid overgrowth.

Key Characteristics & Benefits

Rapid Growth: Covers water surfaces quickly, providing significant shade.
Water Filtration: Excellent at absorbing excess nutrients and improving water clarity.
Fish Food: High-protein (up to 40%) snack for koi and goldfish.
Easy Care: Hardy in USDA Zones 3-10; requires very little maintenance other than thinning.

Pros and Cons

Pros: Natural algae control, provides cover for fish, filters water, easy to cultivate.
Cons: Highly invasive and hard to eradicate once established; can create oxygen depletion if it completely covers a pond, causing fish kills.

Usage Tips

Control: Regularly skim excess duckweed to keep it from covering the entire surface.
Habitat: Thrives in still or slow-moving freshwater.
Size: Individual leaves (fronds) are 1/16 to 1/8 inches long.

Commonly Available Species

Lemna minor (Common Duckweed) is the most common variety for ponds.
