Description

The Bornean leaffish is a small freshwater fish from Southeast Asia, ranging from Thailand to Indonesia. The species grows to about 12 cm and has a deep, laterally compressed body with mottled, brown camouflage that makes it strongly resemble a dead leaf. With its large, far-protrusible mouth it catches small fish and crustaceans as an ambush hunter. It lives in hill streams, peat areas and flooded forests, in fresh and slightly brackish water. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
