The two have quite different outlook on life. Gemini wants adventure and enjoys unpredictability and new things. A typical Gemini doesn't seek very deep care and loving from anyone, since the twins usually enjoy a lot of attention and need not commitment. For the Fish, however, loving and caring touch means life, and commitment is just a way of being. The two will have many conflicts due to this difference, unless they really want to make it work and are willing to change. It's a good thing that both are quite flexible.
