Description

The Sostra pygmy goby is one of the smallest reef fishes (Gobiidae) from the western Pacific. The species stays about 2 cm long and has a translucent, reddish to orange body with large eyes. As a bottom-dweller it lives on coral and in crevices of shallow reefs, often upside down against cave walls, and picks small zooplankton. Through its short life and tiny size it is an important link in the reef food chain. The fish is harmless to humans.
