Water Signs

Water is compatible with water and earth, but not in cases where the signs are on opposite sides of the zodiac chart.
The Cancer-Capricorn opposition can cause conflict in a relationship if Capricorn becomes too ambitious and neglects sensitive Cancer.
The Scorpio-Taurus opposition can certainly ignite a strong physical attraction, but they need more in common for a lasting bond.
In case of the Pisces-Virgo opposition, how will practical Virgo cope with intuitive emotional Pisces? If they are willing, they could learn a bit from each other.
Water has little affinity with fire or air, so they are danger zones.
