The aggressiveness of an Aries is too much for a Scorpio or a Cancer. Leo and Virgo also aren't a good fit because they have such different ideas of what to do.
The temperaments of Leo, Aquarius, and Sagittarius are too boisterous for Taurus to manage, and he prefers a more grounded approach to life.
Capricorn and Taurus people loathe this sign's unpredictability, which they regard as flimsy. Because of their compatibility, Scorpio may have a natural antipathy to Gemini.
Gemini, Sagittarius, and Leo aren't the best partners because they can't satisfy Cancer's need to feel wanted.
The discipline of Capricorn, Taurus, and Virgo could be too much for a fiery Leo. Many of the earth signs have the opinion that Leos need to get over themselves.
It's likely that Sagittarius, Gemini, and Aquarius will test Virgo's tolerance with rule-breaking and unconventional behavior.
A challenge for Libra is that Virgo and Capricorn relationships typically lack the initial spark that Libra is looking for.
Scorpio may find Aquarius to be too cerebral at times, much like the head and the heart do not always see eye to eye. It's best for Scorpio to steer clear of Leo and Aries.
Sagittarius is too rowdy for Capricorn and Taurus, and he lacks the emotional communication skills to be compatible with a Pisces in a serious relationship.
The signs of Leo, Gemini, and Sagittarius have a perception of Capricorn as being overly serious and stuffy, so no compatibility.
The method of thinking that is typical of Scorpio could be challenging for Aquarius, a sign that values reason and transparency more than anything else.
Pisces, who can be sensitive and introverted, doesn't get along well with outgoing signs like Gemini, Sagittarius, and Leo.
