Red Root Floater (phyllanthus fluitans) has evolved from a desert plant to a water plant. Red Root Floater does not grow in the substrate; it grows near the surface of the water. For this reason, the plant makes a suitable open aquarium specimen. Red Root Floater spreads rapidly through runners that form plantlets. The runners require pinching off to prevent the plantlets from shading out submersed aquarium plants. The plant develops bright red leaves under intense light.
