Description: It is a floating freshwater aquatic plant, with one, two or three leaves each with a single root hanging in the water; as more leaves grow, the plants divide and become separate individuals. Duckweed is adaptable, fast-growing, hardy, and has no specific requirements, but is often considered a pest. In good conditions it spreads rapidly, and a small croup may develop to cover the surface of an average aquarium within a week. The light green, oval leaves are 0.12 in (3 mm) long and the root is 1-2 cm long. If regularly thinned, the plant can be very effective in an open-topped aquarium. Duckweed often looks better as an ornamental plant when kept together with other floating species, such as water lettuce (Pistia stratiotes), Azolla spp., or Salvinia spp. It propagates mainly by division.
