Two-spot banded snapper habitat
This species inhabits coral reefs (Lieske and Myers 1994, Kuiter and Tonozuka 2001) and outer reef slopes (Myers 1999, Kuiter and Tonozuka 2001). This species is sometimes solitary but more often occurs in large schools of more than 100 individuals (B. Russell pers. comm. 2015). They feed mainly on small fishes and crustaceans. This species reaches a maximum total length of about 20 cm, but is commonly found to 15 cm (Anderson and Allen 2001). The length at 50% maturity for males in Papua New Guinea is 12.5 cm fork length, while for females the value is 16.7 cm fork length (Longenecker et al. 2013).
This species is caught mainly with handlines, traps, and gill nets. It is considered to be an important market fish in some areas such as Sri Lanka, but generally marketed in small quantities (Anderson and Allen 2001).
