MacGuire recommended Sagittarius for Aquarius. "Aquarius and Sagittarius both have a love for freedom, and they give each other support, inspiration and adventure without any strings attached," he said. They might also like Aries, too. "Aquarius and Aries get along extremely well, as they both approach the world with an excited, can-do attitude in which anything is possible," he said. Mesa suggested air signs. "Aquarius prefers to be social rather than romantic; however, they're highly compatible with sister air signs Libra and Gemini, and other fire signs, especially Leo," she said.
