Lemna Minor, also known as duckweed aquatic plant, is a fast-growing, adaptable, hardy, and easy-going plant. Duckweed produces small and oval leaves measuring about 0.12 inches and we ship it in a 4 oz container or by pound. The light green leaves enhance the look of your tank as this clover-like botanical floats along your open-top aquarium.

In good conditions, you can expect your duckweed aquatic plant to spread quickly — a small amount can cover the surface of an average aquarium in one week. Because of its fast growth, duckweed is great for all types of aquariums, especially those with a heavy biological load. The plant will absorb any excess nutrients from the water column to help keep your tank free of algae.

Many fish, and particularly Koi and goldfish, love to eat duckweed and others will appreciate the shade and cover it provides, making them feel secure.

Maintenance for Duckweed Aquatic Plants

Your duckweed floating plant should be regularly thinned to remove excess material. Balance out the look of this plant with other floating plants like water lettuce or dwarf baby tears.

  • Minimum Lighting Required: Low to Moderate
  • Temperature Range: 41°F - 95°F
  • Tank Placement: Floating

Due to the large temperature range in which duckweed aquatic plants thrive, you can use it in tanks with varied water conditions.

    A little goes a LONG way!

    Plants are very healthy and ordered way to much. Did not realize how well this spreads out over the surface of your tank. Within a few minutes of placing it in my tank, my Endlers were already investigating it. Now my shrimps are going crazy in it, crawling all over the roots and doing their "shrimpy" thing
