As there are other planetary placements within one's Astrological chart, to answer this utilizing only one sign is a bit difficult. Pisces is a water element; Sagittarius is a fire element. The one thing that these two have in common is that both lead with their emotions first and their intellect second. These two signs face life's situations very much the same way, but after that, they can be as different as day and night. That, in itself, is not always bad as we know that opposites attract! As long as the sisters can accept, enjoy, and allow each other their differences, there is no reason they can not get along.
Star signs have little or nothing to do with how people get along.
Any fire sign would be most compatible with Sagittarius. They include Aries and Leo.
