Corona Rainbowfish - Melanotaenia corona

The Corona Rainbowfish was scientifically described by Allen in 1982. Its scientific name is Melanotaenia corona. It was first collected in 1911, by Gjellerup. It was described in 1982 when Allen found Gjellerup's preserved specimens in Amsterdam.

The Corona Rainbowfish can exceed 12 cm (4.7 inches) in length. Its live colours remain unknown, because it is only known from two male specimens from the Sermowai River that were found preserved in a jar at the Zoological Museum in Amsterdam. Judging from the preserved specimens, the Corona Rainbowfish has four dark stripes on the upper side of its body. Each of these stripes is roughly one scale wide and they might have been purple when the fish was alive. The anal fin is dark and the second dorsal fin is also dark, but with a wide white margin. Compared to other Melanotaenia-species, the Corona Rainbowfish has really long second dorsal and anal fins.

Geographical distribution, habitat and conservation
The Corona Rainbowfish lives in Western New Guinea (formerly known as Irian Jaya). As mentioned above, it is only known from two male specimens that were collected from the Sermowai River by Dr. K. Gjellerup in 1911. The collected specimens lived above a waterfall in the Upper Sermowai Valley. Gjellerup had to travel up the Lower Sermowai Rier by boat for three days until he reached the waterfall, and then climb 400 meters (over 1300 feet) to reach the waters above the fall.

The Corona Rainbowfish is listed as “Data deficient” in the IUCN Red List of Threatened Species.
