if you want to raise goldfish well, you should pay attention to the density of feeding. If the number of goldfish is too large, there will be hypoxia. At ordinary times, it is best to decide the feeding density according to the size of the goldfish and the size of the fish tank. Normally, a 60-centimeter fish tank can raise 4-5 10-centimeter goldfish.
Goldfish are cold-water fish, which can adapt to the water temperature of 0-32 degrees Celsius, but their most suitable water temperature is 18-26 degrees Celsius. In winter, breeders need to use heating rods to ensure that the water temperature is constant. In summer, breeders also need to transfer the fish tank to an air-conditioned room, and if they can't, they need to use fans or ice packs to cool down.
Goldfish do not require high water quality. They can survive in neutral or weakly acidic water. Breeders can keep the PH value between 7.0 and 8.5. The pollution of goldfish to water quality is not serious, so the frequency of changing water does not need to be too high, just 1-2 times a week. The amount of water change should not be too much, and it should be controlled at a quarter of the total amount of water.
of goldfish are miscellaneous, and there are many kinds of food that can be eaten. The breeder can feed some animal feeds such as red worms, shrimp, mealworms and nematodes at ordinary times. The protein and fat content of these foods is high, and more feeding can promote their growth. It can also be fed with some synthetic feed to ensure balanced nutrition.
