Bleher's Rainbowfish Chilatherina bleheri

Bleher's Rainbowfish is endemic to shallow, well-vegetated, rocky streams around Lake Holmes and the related lower Mamberamo river system in West Papua, Indonesia.

The male, above left, is deeper-bodied and more colourful than the female, above centre. The back third of his body is red, including his tail fin. The female is greenish - bluish green or olive - with a pale reddish tail.

Bleher's Rainbowfish is threatened by introduced species of carp and tilapia which outcompete them for space and food.
