Wikipedia Abstract

The inland silverside (Menidia beryllina) is a neotropical silverside native to eastern North America, and introduced into California. It is a fish of estuaries and freshwater environments. Inland silversides are quite elongate even for silverside, with lengths 6 to 7 times depth. They have large eyes, a considerably upturned mouth, and a head noticeably flattened on top. Of the two widely separated dorsal fins, the anterior fin is small and has 4-5 weak spines, while the posterior fin is larger, with one spine and 8 or 9 rays. The lengthy anal fin is somewhat sickle-shaped, has one spine and 16 to 18 rays. As befits the name, they are silvery on the sides; the back is somewhat yellowish, and the underside is a translucent greenish. These are small fish, with 15 cm recorded, but most adult
