Habitat and Ecology [top]
Habitat and Ecology: The species typically occurs in the margins of lakes, swamps, and in the slower reaches or backwaters of large lowland rivers, it will also occasionally occur in canals and smaller ponds. It is most frequently found in mesotrophic to eutrophic systems in deep silt and usually in fairly shallow water. Cook and Nicholls (1986) consider that it is a poor competitor and this is why it is not more often dominant.
Systems: Freshwater
