Goldfish might die from heat in summer, but this situation is not common. Goldfish can tolerate a relatively wide range of water temperatures. Generally, they can survive in water temperatures between 0 - 35 degrees Celsius. However, in extremely high - temperature environments, goldfish may die from heatstroke.
The risk of goldfish dying from heat in summer mainly depends on the ambient temperature and water temperature. Generally speaking, 38°C is the maximum tolerable limit for goldfish. But in reality, the water temperature rarely reaches this level, unless it is in a very shallow pool without any sun protection. If the water temperature exceeds 35°C, goldfish may suffer from heatstroke or even die from heat, especially young fish are more vulnerable to high - temperature environments.
To prevent goldfish from dying from heat in summer, the following measures can be taken:
Sun - shading: Build sun - shading facilities over the fish pond to avoid direct sunlight and thus lower the water temperature.
Deepening the Water Level: Appropriately increasing the water depth can effectively prevent goldfish from overheating.
Changing Water: Change the water frequently to keep the water quality clean and avoid discomfort for goldfish due to water - quality problems.
Ventilation: Keeping good ventilation in the breeding environment helps lower the water temperature.
Through these measures, the risk of goldfish dying from high temperatures in summer can be effectively reduced.
