An ancient, but small constellation. Piscis Austrinus is usually pictured as a fish whose open mouth is receiving water that is being poured from the urn carried by Aquarius. The constellation contains one of the brightest stars in the sky, Fomalhaut, thus making it relatively easy to find. Piscis Austrinus can found just below the constellation of Aquarius, low on the horizon for most observers in the United States.
