Blackflag sandperch habitat
The Blackflag Sandperch is found on open rubble/muddy substrates, close to coral reefs. It feeds on small invertebrates and fish. There is evidence to suggest that this fish is a protogynous hermaphrodite, with the two smallest paratypes being female and the larger three male (Randall 1984). This species is found to a depth of 50 m (P. Heemstra pers. comm. 2009).
