生態學
海洋; 淡水; 半鹹淡水 礁區魚類; 深度上下限 0 - 13 m (Ref. 82332). 熱帶; 39°N - 33°S, 29°E - 166°W (Ref. 188)
Indo-Pacific: widespread in Indian Ocean and western Pacific, including entire eastern coast of Africa, Madagascar, Mauritius eastward to Japan, eastern Australia, and Samoa (Ref. 188). Introduced into Hawaii, apparently by accident, and now abundant (Ref. 188). At least one country reports adverse ecological impact after introduction.
印度-西太平洋: 廣泛分佈, 東非，馬達加斯加，模里西斯向東至日本，澳洲東部，美屬薩摩亞。 引入夏威夷中了 - 顯然地由於意外事件 - 在那裡它現在很豐富。 (出版的大多數的先前資料被稱為 Herklotsichthys punctatus). 至少一個國家報告引入後的不利的生態衝擊。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 12.3, range 7 - 17 cm
Max length : 25.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 48635); common length : 10.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188)
背棘 (總數): 0; 背的軟條 (總數): 16-23; 臀棘 0; 臀鰭軟條: 15 - 21. Diagnosis: Body slender, its depth 18 to 30% of standard length; presence of two fleshy outgrowths on the hind margin of the gill opening; sharp belly with keeled scutes, 16-19 pre-pelvic and 12-14 post-pelvic scutes (Ref. 188, 3259). The presence of elongate wing-like scales underneath the normal paired pre-dorsal scales separate it from all other species except the two Australian species with prominent black spots on the flank, Herklotsichthys koningsbergeri and Herklotsichthys Species A, and the unspotted Herklotsichthys Species B, which has dusky tips to dorsal and caudal fins and more lower gill rakers, 36-42 vs. 33-36 in H. quadrimaculatus (Ref. 188). Flank silvery with an electric blue line preceded by two orange spots (Ref. 188).
在成對的前背部的鱗片的下面細長翼狀的鱗片除了 H. koningsbergeri 以外區隔它和所有的其他種，而且 Herklotsichthys 種一在側面與有對背鰭與尾鰭鰭與更多的下鰓耙的暗色尖端的 Herklotsichthys 種 B 上那裡有突出的黑色斑點。 側面銀色的有被前面有被位於每個鰓蓋上的二個橘色的斑點的一條鐵青色線。
Adults form schools near mangroves, shallow coastal bays and lagoons during the day and moves further offshore into deeper water by night (Ref. 188, 48635); at depths of 0-13m (Ref. 58302, 82332). Known in mills around in large schools under wharves or along sandy beaches in protected bays (Ref. 26367). Pelagic (Ref. 58302). Feeds on zooplankton, mainly at night, chiefly copepods in juvenile stages, but larger prey as adults (chaetognaths, polychaetes, shrimps and small fishes) (Ref. 188). Breeds during its first year and probably survives only a few months after maturity (Ref. 188). Marketed fresh and dried salted (Ref. 188). Usually parceled in leaves and baked in a motu oven. Do not recover quite as quickly as other species of baitfish after heavy fishing (Ref. 26367).
成魚形成魚群紅樹林附近，淺灘近岸海灣與潟湖在白天期間而且移動進一步離岸進入較深的水域夜晚.(參考文獻 188,48635) 在壓榨機在遮蔽的內灣中在碼頭下面大群魚群周圍或者沿著沙灘。 (參考文獻 26367) 是大洋性的。 (參考文獻 58302) 主要在晚上覓食浮游動物, 主要地橈足類幼生, 與當成魚時, 吃較大的獵物 (毛顎類動物，多毛類動物，蝦與小魚). 在第一個上繁殖年而且可能只平安渡過數個月成熟後。 在市場上銷售生鮮或乾漬.。 (參考文獻 188) 在一個 motu 烤箱中通常在樹葉中分配而且燒烤.。 無法完全恢復在大量的漁撈之後像其他種的誘餌魚一樣的很快地.(參考文獻 26367)
