Another behavioral cue that can help determine gender is the way the fish swims. Males tend to swim more actively and erratically than females, especially during breeding season. Females tend to swim more calmly and steadily.
Other Methods
Aside from visual inspection, physical characteristics, and behavioral cues, there are other methods that can be used to determine the gender of a goldfish. Here are some additional methods:
- Genital Inspection: This method involves inspecting the genital area of the fish to determine its gender. Males have a more prominent genital papilla than females, which can be seen when the fish is viewed from the side.
