Freshwater fishes of  Southeast Asia

Awareness of the amazing diversity of Southeast Asia's marine fishes is high: coral reefs, for example, are highly photogenic.  The diversity of freshwater aquatic systems, such as forest streams, swamps, pools and lakes is much less appreciated.  The species illustrated on this web page thus serve as an introduction to this incredible diversity.

All images in this section are taken in natural habitat: the perspective is that of an observer standing next to a forest stream peering down into the water.
