As long as it is at normal feeding density, breeders can choose not to oxygenate Lanshou goldfish, because they are not a kind of fish with high oxygen consumption. As long as the water is changed frequently and the water quality is clean, the dissolved oxygen in the water is enough for them to absorb. But when the feeding density is too high, they need to be oxygenated. Because there are too many fish, the water quality will deteriorate faster and the oxygen content will decrease. Breeders need regular oxygen to ensure that they can survive normally. In addition, when the air pressure is low on rainy days, breeders also need to give them oxygen to avoid their lack of oxygen. Also, when the temperature is high, the dissolved oxygen in the water will also decrease, and the breeder should also take oxygen.

If Lanshou goldfish is raised outdoors, it needs to be heated with a heating rod, because the outdoor temperature is low in winter and the temperature difference between morning and evening is large. If the heating rod is not used, the water in the fish tank will freeze easily, and Lanshou goldfish may freeze to death. If the Lanshou goldfish is raised indoors, you can choose not to heat it, because the Lanshou goldfish has strong adaptability to water temperature and the indoor temperature is not too low in winter, so you can not use a heating rod.
