An offshore species found mainly around coral reefs. Generally solitary or occur in small schools of six or less. Preys on small schooling fishes such as Decapterus, Caesio, Nasio, Cirrhilabrus, Pterocaesio and squids. Caught mainly by pole-and-line. Marketed canned and frozen (Ref. 9684, 48637). Adults may be ciguatoxic (Ref. 37816). Minimum depth reported taken from Ref. 128797.
一個外海種主要地珊瑚礁的周圍發現。 通常獨居性的或六以內形成小群魚群。 捕食小的群游性魚例如 Decapterus ， Caesio ， Nasio ， Cirrhilabrus ， Pterocaesio 與烏賊。 在市場上銷售罐裝及冷凍.(參考文獻 9684) 成魚可能具有熱帶海魚毒.(參考文獻 37816)
