It looks very similar to the water hyacinth, with perfectly round, bright green leaves. It is likely that high organic inputs into water bodies will also reduce oxygen levels in the systems (Akers, 2010). It is also good in traditional aquariums, because the fine, long and decorative roots provide protection to gouramies and other surface fish that like the roots of floating plants.
