About
Amazon frogbit (Limnobium laevigatum) is a floating plant in the family Hydrocharitaceae, native to Central and South America. It spreads round leaves about 2-3 cm across on the water surface and trails roots into the water column. Spongy aerenchyma on the leaf undersides provides buoyancy, keeping it stably afloat. Requiring no CO2 or substrate fertilizer, it absorbs excess nutrients vigorously, so it is often introduced for algae control and water purification. It propagates rapidly via runners producing daughter plants, so it should be thinned when crowded. Because it shades the tank below, balance with submerged plants is important. The dangling roots provide shelter and spawning sites for small fish and shrimp. Hardy and beginner-friendly, though leaves are prone to damage from strong surface flow or splashing.
