Mars in Pisces has little drive when it comes to attending to their own needs. They put off some tasks and wait until the last moment to act.
That changes when someone needs help. The wish to serve can set them in motion promptly and with an energy that didn’t appear when the task was for themselves. That is why they may seem apathetic in some circumstances and agile and enthusiastic in others: what matters is what they act for and for whom.
In this description, activities such as tai chi, yoga or martial arts suit their search for a physical experience with an inner meaning. Connection with what they do weighs more than movement out of obligation.
Their character is usually gentle, but they may react with great intensity if they feel their willingness to serve has been abused. The image of the fish that turns into a piranha expresses that change of tone. They don’t seek out arguments, although they may reach a limit that those who received their help had not noticed.
