Care notes
Diamond-shaped silver body with yellow and black markings. Strictly brackish to marine — keep at 1.010–1.020 SG. Active, fast schooling fish needing plenty of open swimming space. Juveniles can tolerate lower salinity; adults prefer near-marine. Gets large quickly.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
