Western Pacific: Bali and the Philippines east to Samoa, north to Ryukyu Islands, south to Rowley Shoals, the southern Great Barrier Reef, and New Caledonia; throughout Micronesia. Replaced by the uniformly yellow species ovalauensis in Fiji, and by Meiacanthus tongaensis in Tonga (Ref. 37816).
西太平洋: 巴里島與菲律賓東至美屬薩摩亞, 北至琉球群島, 南至羅雷淺灘,大堡礁的南方與新加勒多尼亞; 在密克羅尼西亞各處。 在斐濟被全身黃色的種 ovalauensis 取代了, 與藉著 Meiacanthus tongaensis 在東加.(參考文獻 37816)

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 4; 背的軟條 (總數): 25-28; 臀棘 2; 臀鰭軟條: 15 - 18. Identified by the blue-edged diagonal black line from the eye and yellow dorsal fin or back. Adults have long filaments on the caudal fin tips; length without filaments (Ref. 48636).
鑑定特徵為邊緣藍色的斜黑色的線從眼與黃色的背鰭或背面了。 在尾鰭頂端上成魚有長的絲狀突起; 沒有絲狀突起的長度.(參考文獻 48636)

生物學特性     字彙 (例如 epibenthic)

Adults are found solitary or in pairs (Ref. 90102) in lagoon and seaward reefs below the surge zone to 30 m depth (Ref. 9710). A common species, often seen along slopes and drop-offs, adults sometimes in small groups (Ref. 48636). Feed on zooplankton and also on small benthic invertebrates. Inoffensive, but immune from predation (Ref. 9710). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Mimicked by Ecsenius bicolor and Plagiotremus laudanus (Ref. 90102).

在對 30 公尺深的湧浪區之下棲息於潟湖與臨海礁石。 (參考文獻 9710) 一種常見的種, 時常見到沿著斜坡與海峭壁,成魚形成小群魚群有時.(參考文獻 48636) 捕食浮游動物以及在小型底棲的無脊椎動物上。 無攻擊性, 但是不會被掠食.(參考文獻 9710) 卵生的.(參考文獻 205)
