Found inshore (Ref. 75154). Exhibits the black gut phenomenon. In nocturnal predators, it appears to serve to conceal bioluminiscent prey in the stomach cavity (Ref. 46685).

Commonly found in clear-waters of seaward reefs; on reef crests and slopes, where usually shallow, and along deep drop-offs to 25 m (Ref. 48635). Feeds on polychaetes and other small benthic invertebrates at night; cryptic under ledges or in holes by day (Ref. 1602). Solitary or in small groups (Ref 90102).

分布於印度-太平洋區，西起東非、紅海，東至萊恩群島，北至台灣，南迄新加勒多尼亞。台灣主要分布於西南部、南部、東部、綠島及蘭嶼等海域。

通常以下雜魚處理，用作魚飼料，有時會曬成小魚乾自家食用，並無任何經濟價值。
