生態學

印度-太平洋: 肯亞到南非北部與向東至法屬玻里尼西亞與皮特凱恩群島。 未知的從紅海，亞丁灣，阿曼灣，波斯灣 , 與印度的海岸。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 17 - ? cm
Max length : 28.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5222)
背棘 (總數) : 9; 背的軟條 (總數) : 14 - 16; 臀棘: 3; 臀鰭軟條: 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.
棲息於清澈的, 外圍礁石區域的淺水域。 也發現於潟湖，礁背的區域, 與在礁頂上。 吃小魚 (68%) 與甲殼動物。
