Description

The Redder fighter is an Asian labyrinth fish (Osphronemidae) from slow-flowing, soft and oxygen-poor fresh water of Borneo in Southeast Asia. The species grows to about 5 cm and has a slender body; males are finely coloured with red, blue or green tints and spreading fins. With a labyrinth organ it can gulp air at the surface. Depending on the species the male broods the eggs in a bubble nest or in his mouth. It eats small invertebrates and insect larvae. The fish is harmless to humans.
