How can you tell the difference between a male and female rosy red fish?

Answer 1

to tell the difference between male and female rosy red minnows, look for vertical stripes and fleshy growths on the head. Females lack both.

Answer 2

Male rosy red fish tend to have brighter colors, especially during breeding season, and can develop small white tubercles on their head. Female rosy red fish are usually larger and have more rounded bodies. Additionally, a trained eye can differentiate between the genital papilla of males and females, which is located near the fish's vent.

Answer 3

All goldfish are sexed the same way. When in breeding season, the males get little white spots on the gills and the females get a bulging tummy and lay eggs when sucessfully breeded.
