This constellation south of Aquarius is made prominent by the presence of the star Fomalhaut, magnitude 1.2, although there is little else of note. To the ancient Greeks, Piscis Austrinus was the parent of the two fish of the zodiacal constellation Pisces. In the sky, the stream of water from the jar of Aquarius flows toward the mouth of the fish, marked by Fomalhaut, an Arabic name meaning "fish's mouth."
