Limnobium Laevigatum is the best complementary floating plant for aquariums. Originated from South Africa, this pristine plant showcases fine, long, and decorative roots. It can grow approximately 1-5 cm tall and its leaves from 5-15 cm wide. Its roots also yield protection to gouramies and other surface fish that like the roots of floating plants. When well maintained with proper nutrients and light intensity, new leaves will appear above the water surface. Plus, when the nutrient level in the water decreases, it will grow much slower which makes it a great indicator of the available nutrients.
