Goldfish do not require high water temperature and can adapt to a wide range of water temperature, but their most suitable temperature is 18-22 C. Breeders can keep the water temperature in this temperature range at ordinary times.
It should be noted that although goldfish have strong adaptability, they can not accept violent fluctuations, so breeders usually need to ensure that the water temperature is constant to avoid temperature differences exceeding 2 degrees Celsius.
Goldfish like weak alkaline water, so it is better to control the PH value between 7.5 and 8.0 in the usual feeding process. The pollution of goldfish to water quality is not serious, and the water can be changed 1-2 times a week at ordinary times. When the weather is hot, it can be changed three times a week. If you use tap water to raise goldfish, you need to expose it to the sun for 2-3 days to volatilize the chlorine in the tap water before it can be used by goldfish.
It should be noted that the amount of water changed by goldfish should not be too large, and the amount of water changed each time should be controlled at a quarter of the total amount of water. If conditions permit, a circulating filtration system can be installed.
goldfish has miscellaneous feeding habits. Generally, they will eat the feed that ornamental fish eat. Breeders can usually feed some red worms, shrimp, mealworms, water fleas, tubificidae and so on. If you don't have time, you can also feed some synthetic feed.
Goldfish feeding needs to pay attention to the diversity of food to avoid their single feeding habits or single nutrition. Usually feeding should also be regular and quantitative, preferably in the morning and evening, if the temperature is low, you can only feed once at noon.
Goldfish do not require high environmental requirements, so breeders only need to prepare heating rods, oxygen pumps and filters. The heating rod does not need to be opened when the temperature is suitable, and the oxygen pump does not need to be opened all day. If the feeding density is normal, it can be opened for 2 hours a day. The filtration system can be opened for 6-10 hours a day, which can ensure clean water quality.
