if they are exposed to the sun? Goldfish will die if they are exposed to the sun, because the high temperature will make the oxygen in the fish tank less and less. Although the demand for oxygen in goldfish is not high, long-term hypoxia will lead to discomfort in goldfish. When the lack of oxygen is serious, the goldfish will die. In addition, the water in the fish tank will be exposed to the sun, the water temperature will increase, goldfish can only adapt to the water temperature within 30 degrees Celsius, if the water temperature is higher than 30 degrees Celsius, goldfish will have reduced immunity. If goldfish are exposed to high temperatures for a long time, they will gradually die.
goldfish 1. Water temperature: Goldfish is a cold-water fish with strong adaptability and can survive at water temperatures between 0 and 30 degrees Celsius. But if breeders want them to grow better, they need to keep the water temperature between 18 and 26 degrees Celsius.
2. Water quality: Goldfish like weak alkaline water, and breeders can control the PH value between 7.5 and 8.0. The pollution of goldfish to water quality is not serious, and the breeder can change water twice a week to ensure clean water quality.
3. Feeding: Goldfish are omnivorous animals and can eat normal food. Breeders can feed with animal feed and synthetic feed, which can not only ensure adequate nutrition, but also ensure balanced nutrition. Goldfish do not know hunger and satiety, breeders should pay attention to regular and quantitative feeding.
