Pisces gets along well with those constellations.

Pisces can't get along with those powerful constellations. The most obvious constellation is Leo, because Leo has a strong desire to conquer. If Pisces doesn't obey them, Leo will feel unhappy, and Pisces will feel scared at this time, so they should be less fit.

And Capricorn. Capricorn's haggle over every ounce conflicts with Pisces' caution. Imagine that a more realistic person meets a more dreamy person, and it is more difficult for them to get along. Moreover, Capricorn has higher requirements for others. From this point of view, Pisces certainly can't meet their requirements, so Pisces may escape from Capricorn because of fear.

Then virgo. Virgo is a rigorous constellation. They treat themselves and others with high standards. Pisces has very low requirements for themselves, so in Virgo's eyes, Pisces is really weak. If Virgo doesn't take care of Pisces so much at this time, the two of them will definitely not get along. Pisces will definitely be scared away by Virgo's momentum. There is no way. Virgo is such a constellation that is strict with itself, and they will not lower their requirements easily.

To sum up, Pisces is the weaker of the twelve constellations. If they encounter a stronger constellation, they will feel powerless. In this case, it is easy, but they want to escape. If two people don't communicate together, it will be difficult to get along, so I think Pisces and more powerful constellations can't get along.
