In the wild, just a few dozen fish of this species survive in a single river. The introduction of carp and tilapia has decimated its numbers and could soon prove fatal to the species.
The female is much larger than the male, who rarely measures more than 3 cm. She is also less colourful.

This is a viviparous fish. In order to breed, the male mates with the female, by means of a modified anal fin.
