Both the signs of Sagittarius and Pisces are ruled by Jupiter. This means that they have some immediate understanding of each other, and also have similar ways of thinking. Pisces is also strongly influenced by the planet of Neptune, which makes them dreamy, sensitive and even magical. These qualities appeal to the Sagittarian idealism and they both feel there is a deeper meaning to life.
The two people can spend a lot of time together tuning in to these common interests and building their relationship on them. The Piscean needs time to adjust to their surroundings, and likes to dream their ideas at their own pace. This is the opposite of the Sagittarian approach who like to get things done now. They rather implement dreams than dream them. This difference can be a point of conflict in this relationship. The Piscean wants to settle into a known environment, create a family and get down living a life that is nurturing. That does not mean they won’t enjoy exploring the world with their partner. The right Piscean partner will calm the Sagittarian emotional and volatile restlessness and share in the thrill of what they have to offer.
