The surf silversides are a small family, Notocheiridae, of salt water atheriniform

Atheriniformes

Atheriniformes, also known as the silversides, is an order of ray-finned fish that includes the Old World silversides and several less-familiar families, including the unusual Phallostethidae...

 fish found in tropical and temperate seas.

They are small fish, typically less than 8 centimetres (3.1 in) in length, with silver stripes and a keel-shaped underside. They form large schools, and are often found in the surf close to the shore, hence their common name.
