Pisces and Cancer are two water signs that are similar in many ways. They're both emotional, romantic, and give their all to their relationships. According to Welch, Cancer will understand Pisces like no other. There are a lot of things that work in this pairing. However, there is a chance that Pisces will get bored with the zodiac's homebody. They're also two highly sensitive signs and may get put off by each other's ever-changing moods. Regardless, these two have a strong emotional, mental, and physical connection. "For Pisces, Cancer would be the one that got away," Welch says.

Scorpio is another water sign that Pisces get along with really well. For one, they're both very intense when it comes to love. Scorpio likes getting to know their partner on a deep level, while Pisces likes being "one" with their partner. Besides that, these two signs make a very hot and sensual partnership. However, Scorpio's intensity can be a little too much for the more go-with-the-flow Pisces. If they were to break up, Welch says Pisces will likely regret ending things with Scorpio for physical reasons. No other sign will be able to make Pisces feel the way Scorpio did.

Capricorn and Pisces make an interesting pair because they're so different. Capricorn is a practical Earth sign, while Pisces like living in their own fantasy worlds. However, Capricorn is the type of partner that Pisces needs. "Capricorns provide Pisces with stability and can talk the Pisces down when making decisions," Welch says. "They provide Pisces the grounding they need." Although Pisces may find Capricorn to be a little too serious for them, they will look back and appreciate how much they could grow as a person in the relationship with Capricorn.
