Overview

Found in schools, during the day in caves, harbours, under ledges and around shipwrecks, dispersing at night, hunting for food, high above the bottom, over sheltered lagoons, reef margins and seaward reefs.

Sweepers school during the day, but at night they float high above the bottom to hunt for larger zooplankton.
Several species are triangular shaped.
