البيئة
بحري مرتبطة بالشعاب; نطاق العمق 0 - 60 m (Ref. 5222), usually 3 - 15 m (Ref. 9710). Tropical; 34°N - 30°S, 33°E - 131°W (Ref. 5222)

Length at first maturity / الحجم / وزن / العمر
Maturity: Lm ?, range 17 - ? cm
Max length : 28.0 cm TL ذكر/ مختلط الجنس; (Ref. 5222)
الأشواك الظهرية (المجموع) : 9; الأشعة الظهرية الناعمة (المجموع) : 14 - 16; شوكة شرجية: 3; أشعه شرجية لينه: 8 - 9. This species is distinguished by the following characteristics: greatest body depth 2.7-3.1 in standard length; body scales ctenoid except cycloid scales ventrally on abdomen; rounded caudal fin; pelvic fins usually not reaching the anus, 1.8-2.2 in head length Colour of body reddish brown anteriorly, dark brown posteriorly; caudal fin with 2 white to bluish white bands that converge posteriorly (Ref. 90102).
Adults inhabit clear, shallow waters of outer reef areas, in lagoons, back-reef areas, and on the reef-top. As solitary individuals (Ref. 90102), they prefer healthy coral reef in shallow areas, and are therefore greatly affected by reef degradation (Ref. 89707). They feed on small fishes (68%) and crustaceans. Because of its small size, the darkfin hind is not of much interest as a food fish (except perhaps to subsistence fisheries), but it does well in an aquarium and may find a market as an aquarium fish. They are caught with hook-and-line, gill nets, and in traps (Ref. 39231). Minimum depth reported taken from Ref. 128797.
