Can goldfish survive in 78 degree water?

Yes, goldfish can survive in 78-degree water. The ideal temperature range for goldfish is between 65-72 degrees Fahrenheit, but they can tolerate temperatures up to 85 degrees Fahrenheit for short periods of time. However, it is important to note that goldfish are cold-blooded animals, so their body temperature will match the temperature of the water they are in. Therefore, if the water temperature is too high, the goldfish's body temperature will also be too high, which can cause stress, illness, or even death. For this reason, it is important to keep goldfish in water that is within the ideal temperature range of 65-72 degrees Fahrenheit.
