Highighted items on the list are where Hyporhamphus quoyi may be found.
Remarks Inhabits more turbid and estuarine situations than does Hyporhamphus dussumieri and is not found in oceanic islands (Ref. 9843). May enter rivers (Ref. 559). Found in medium to large-sized rivers of the lower Mekong (Ref. 12975); also inhabits coral reefs (Ref. 58534). Occurs in schools (Ref. 3132).
