Goldfish Spawning Season and Signs
Goldfish's main breeding season is spring (late March to May) when water temperature rises above 15–18°C. Male chasing behavior—where males pursue females—is a sign of imminent spawning. If the female's belly becomes visibly rounded and full, spawning is imminent.
If you plan to breed goldfish, separate males and females into different tanks in autumn and winter, then house them together when water temperature begins rising in spring. This reliably triggers spawning.
