Hi there! I'm no longer breeding or keeping Fancy Xiphophorus, but when I did breed an already bred (Fancy- not Hybrid) Swordtail or Platy I experienced mixed broods of the previous male/s offspring and the new male's offspring after a couple of drops.
The old sperm is weaker than the new and eventually you'll no fry from the old sperm.
