Population [top]

Population:Coradion melanopus is moderately common and the most abundant member of the genus at Cenderawasih Bay, West Papua, Indonesia (G.R. Allen pers. comm. 2009). A total of five to ten individuals per dive were recorded on inshore reefs during a 2008 survey. Members of this genus are usually seen in relatively low numbers which is not necessarily indicative of a declining population (G.R. Allen pers. comm. 2009).
Current Population Trend:Stable
Additional data:
Population severely fragmented:Unknown

This species is usually seen feeding on barrel sponges (Xestospongia). It can be found to a maximum depth of 50 m. This species lives singly or in pairs when breeding.
Generation Length (years):1-2
