Overview
This Asian grass floats thanks to swollen leaf sheaths. Its fairly broad, lance-shaped, water-repellent leaves make a surface cover very different from duckweed or a floating rosette. In open air, on damp soil, it also grows in a creeping way.

Growing in the aquarium
Let it grow its shoots at the surface rather than trying to make it a fully submerged plant. Provide enough light and room for fast growth. Fragments let you renew the cover. Thin the planting if it becomes too dense, to keep light for the plants below.
