Duckweed (Lemna minor) is a tiny, fast-growing floating plant that brings big benefits to freshwater aquariums. It provides shade and shelter for shrimp, bettas, fry, and other small fish while helping to control algae growth by blocking excess light. Duckweed absorbs nitrates and other waste compounds, making it a natural aid for maintaining healthy water quality. It thrives under moderate to high lighting and spreads quickly, making it an ideal option for tanks needing nutrient export or surface coverage. To manage growth, simply scoop out excess as needed. Its floating mat can also encourage natural behavior and surface foraging. Duckweed is especially popular in breeding setups and natural-style aquascapes. Safe for all freshwater livestock. Whether you’re looking to improve tank balance or add a touch of greenery, duckweed is a hardy, helpful plant for any aquarist.
