Description

The goldspot halfbeak is a livebearing freshwater halfbeak (Zenarchopteridae) from clear, soft fresh water of Borneo in Southeast Asia. The species grows to about 5 cm and has a very slender, elongate body with an extended lower jaw; males bear glittering golden spots and colourful fins. As a surface fish it swims just below the waterline of forest streams and snaps at insects falling on the water; fertilisation is internal. The fish is harmless to humans.
