Duckweed (Lemna minor) is a common floating aquatic plant that can be beneficial in aquariums under certain conditions.
It is known for its rapid growth and ability to absorb excess nutrients such as nitrates and phosphates from the water. This can help to reduce algae growth and improve water quality in the aquarium.
It is found in calm, still waters in the wild. It thrives in freshwater environments with plenty of sunlight.
Duckweed provides shade for aquarium inhabitants, which can be beneficial for fish and other plants that prefer lower light levels. It also provides shelter for small fish and invertebrates.
Like other aquatic plants, duckweed contributes to oxygenating the water through photosynthesis, which is essential for the health of fish and other aquatic organisms.
While duckweed can be beneficial in many aquarium setups, it may not be suitable for all tanks. Some fish species may uproot or eat duckweed, while others may benefit from its presence. Additionally, in heavily filtered aquariums, duckweed may struggle to establish itself due to the strong water flow.
Propagation: Duckweed reproduces quickly, so it’s important to monitor its growth to prevent it from completely covering the surface of the water. Regular removal may be necessary to keep it in check.
