there will be a fish

I don't see a Cancer Sun but you could sell me on a Cancer Moon - he *needs* love, he needs emotional attachment. But his tendency to wear his heart on his sleeve (and then take off his shirt) argues against any "secretive" signs such as Pisces, Scorpio, or Cancer. He doesn't have enough ego to be a Leo; you could sell me on a Virgo or Libra combo since he tends to be quite nonjudgmental and accepting of people's differences. I would say he's not a Taurus Sun either because he's not stubborn to the point of immovability either in emotional or intellectual ways. Could be an Aries, Cardinal Fire - he's got that energy.
