An undescribed yellow to greenish rainbowfish with reddish fins, a yellow midlateral stripe, and narrow black stripes forming a distinctive zig-zag pattern along the lower side. The species is restricted to the middle reaches of Running River in the Burdekin River catchment, north of Townsville.

Although Running River Rainbowfish have been known since 1982, they were previously considered to be a variety of the Eastern Rainbowfish (Melanotaenia splendida splendida) or perhaps a distinct species. Research has now shown that the species is genetically distinct from other rainbowfishes.

Distribution |
Endemic to a small stretch of Running River between two gorges, in the Burdekin River catchment, north Queensland. The species has also been translocated to two nearby creeks. |

Australian Society for Fish Biology (ASFB): Critically Endangered Unmack & Hammer (2016) found that Eastern Rainbowfish, Melanotaenia splendida splendida, had been introduced into the upper reaches of Running River, above the upper gorge, and were rapidly moving downstream, hybridising and introgressing with the undescribed Running River Rainbowfish - which will eventually lead to the extinction of this species in Running River. In September 2016, as a result of this hybridisation threat, the Running River Rainbowfish was listed as Critically Endangered by the ASFB Threatened Fishes Committee. A captive breeding program, initially established at the University of Canberra, and now also at James Cook University, is developing "insurance" populations that can translocated to other suitable creek systems - with the ultimate goal of re-establishing Running River Rainbowfish in Running River. |
