Description

The slender silverbiddy is a fish of the mojarra family (Gerreidae) from the Indo-West Pacific. The species has an elongate, silvery body with a highly protrusible mouth that it can extend downward as a tube to sift the bottom. It prefers coral-rich areas and migrates to specific sandy areas near the outer reef edge to spawn in the late afternoons during full moon. On the bottom it sifts small invertebrates from the sediment. The species is harmless to humans.
