Pisces can teach Cancer how to be more compromising and tolerant, and Cancer is quick to employ this knowledge in various situations.
They both share a lot of positive energy, which helps them to become better at whatever they are doing. Cancer should be more tolerant when it comes to inconsistency of character which Pisces is known for.
