Conservation ActionsThere are no conservation actions in place for this species. Further surveys are required to see if this species is still extant.
Location InformationThis species is known only from the Mbuta Basin, approximately 8 km north of Etna Bay in the narrow isthmus known as the Birds Neck region of West Papua, Indonesia. Formerly considered a remote, isolated area it is now accessible by a road that originates at a logging camp at Kayumerah Bay, immediately west of the entrance to the much larger Etna Bay (G.R. Allen pers. comm. 2019).
Population InformationThis species is considered one of the rarest rainbowfish species as it has not been seen since the first collection in 1997, despite several subsequent attempts to locate it, the latest of which was in 2016 (G.R. Allen and Kadarusman pers. comm. 2019).
There are large fluctuations in the water level of the habitat and these are likely to be leading to fluctuations in the population. However, it is not clear if these are of great enough magnitude to qualify as extreme fluctuations.
