LenKa [72]

Answer:

I don't know what your fish looks like but I will try my best :)

To accommodate the developing eggs, the mother's body expands, becoming deeper and broader. A few days before delivery, she develops a bulge below the gills, her outline becoming fairly square in this region, while the gravid spot has enlarged its area. The female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.
