Description

The Marsh dartfish is a tiny dartfish or wormfish (Gobiidae) from shallow, clear coastal and mangrove water of the Indo-West Pacific. The species grows to only about 3 cm and has an extremely slender, semi-translucent body, often with a fine longitudinal stripe and large eyes. As a social fish it hovers in schools just above sand, coral and roots and dives into a burrow when threatened; it snaps at small zooplankton. The fish is harmless to humans.
