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.

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: Moderate
  • Temperature Range: 42.8°F - 91.4°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.

    Majority of the duckweed was green and healthy, and is doing well in my tank.

    Duckweed was clean, alive and well when received. I gave a 4 rating because my 2nd order contained many fewer plants than my first order.

    Healthy plant that comes in a small cup. I used it on my 20 gal, a 5 gallon, and a three gallon and I still had to throw half of it away simply because it came with so much! You definitely get your moneys worth and more.

    Grew incredibly fast as hoped, and has been very easy to take care of! My gourami and angel fish really love the duckweed and the gourami spends more time in the upper water column now like he's supposed to
