Distribution & Habitat
Currently known only from the Ajamaru Lakes region in Vogelkop Peninsula, Irian Jaya. They were collected about two kilometres east of Ayamaru (Ajamaru) Lake in the centre of the Vogelkop Peninsula. The lakes are located at the headwaters of the Ajamaru River which drains into the Kais River, eventually flowing into the Ceram Sea to the south. Habitat variable, relatively clear shallow water, with abundant vegetation. The lakes and streams are alkaline with pH always slightly above neutral (7.1-7.6). Water temperate about 26-27°C. Co-occurs with Melanotaenia boesemani. They have also been collected from the Manggosa and Saengga rivers (Siripa Creek, Burma Hill Creek, Texas Creek) on the north coast of the Bomberai Peninsula, where they co-occur with Melanotaenia irianjaya. Both rivers flow north into Bintuni Bay .
Live specimens were collected by Heiko Bleher in 1998 and Charles Nishihira in 2004. However, they are not readily available in the retail aquarium hobby being mainly kept by a few aquarists who are principally interested in rainbowfishes.
