While Cancers are extremely compatible with Scorpios and Pisces signs, they make the best long term partnerships and marriages with Capricorn. Capricorn and Cancer create full and loving families because both signs are adept at working hard at relationships and balance each other with doses of common sense and nurturing tendencies.
As a cancer, you will be very persistent in your work and are known for being able to complete tasks successfully, especially when left to your own devices. You are more inclined to save and invest your money, but do have some splurging tendencies. Regardless, Cancer is a very resourceful sign so you can make any financial situation work for you.
