Potamogeton pusillus, commonly known as Lesser Pondweed, is a submerged aquatic plant belonging to the Potamogetonaceae family. It features slender, branched stems with linear, translucent, bright green leaves that can form dense underwater meadows. It is ideal for cold-water aquariums, natural ponds, or as an oxygenating plant in shallow bodies of water.

Care tips
This species prefers clear, calm waters with good exposure to indirect or moderate sunlight. It doesn't require a specific substrate, as it can root in sand, gravel, or even float freely, though a nutrient-rich substrate will encourage more vigorous growth. Maintaining water quality is crucial; avoid sudden changes in water temperature or chemistry, as it is sensitive to pollution. A common mistake is insufficient light, which can lead to slow growth and weak leaves.
