Common Goldfish Temperature: Ideal Water Temp
Ideal: 60-74°F (16-23°C)
The Common Goldfish is a coldwater / subtropical species. Aim for the middle of its range, around 67°F, and keep it steady — sudden swings stress fish more than a stable temperature.
This species tolerates cooler water, so it can often be kept without a heater in a room near 60-74°F, though a heater still improves stability.
