Pisces is the last star sign in the Zodiac and its symbol is the fish. Dreamy, creative and emotional, Pisces will be born between Feburary 19 and March 20. A water sign, Pisces can immerse themselves into a group very easily but they do have a tendency to retreat into sentimentality, and can be indecisive and unrealistic. Ruled by Neptune, Pisces are most compatible with the star signs Scorpio, Cancer and Capricorn.
