Length at first maturity / Size / Gewicht / Alter
Maturity: Lm 12.5, range 10 - 15 cm
Max length : 30.0 cm FL Männchen/unbestimmt; (Ref. 108763)
Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 30 - 36; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 25 - 30.
Adults are found in the sublittoral zone and may enter semi-enclosed sea areas (Ref. 11230). In Guam, it is encountered in large numbers around fish aggregating devices, buoys anchored offshore to attract pelagic game fishes.
