Ptereleotris heteroptera has a very elongated pale blue body and two relatively low dorsal fins. Pink pectoral-fin bases and a dark tail spot complete its delicate pattern.

On Indo-Pacific reefs it collects current-borne zooplankton above the bottom. Adults usually feed close together and share rock or rubble shelters. Young may form very large gatherings.

Długość całkowita (TL): od końca pyska do końca płetwy ogonowej. Przykład, nie średnia populacji. Widok przedni ma przybliżone proporcje.
