Description
The Estuarine Round Herring, likely *Spratelloides gracilis*, is a small, silvery, schooling fish characterized by its slender body, prominent silver lateral stripe, and deeply forked tail. Found in coastal and estuarine waters across the Indo-Pacific, these active fish are primarily planktivorous. They thrive in groups and require stable brackish to saltwater conditions.
