About
Atherina boyeri is widespread across the coastal and inland waters of Europe and the Mediterranean basin, tolerating a broad range of salinities from fully fresh to marine. Its streamlined, silvery body and active schooling behaviour make it an interesting and unusual aquarium subject. A robust, undemanding species that benefits from space to swim fast in large groups.
