Can without an oxygen pump? Small goldfish can also be fed without an oxygen pump. As long as the water quality is suitable, the density is reasonable, and more attention is paid in the process of feeding, there will be no big problem. Compared with oxygenated fish tanks, when there is no oxygenation, the density of goldfish must not be too large, otherwise it is easy to make goldfish anoxic. Moreover, it is better to choose a fish tank with a larger opening, so that the contact area between the water surface and the air is larger, so that more oxygen can enter the water. The feeding time must not be excessive, and the feeding time should not be chosen at night when the oxygen in the water is low. There is no oxygen pump, and it is necessary to change the water for the goldfish regularly to ensure the appropriate water quality.
, although the small goldfish is very hungry, but has not fed will also die. As long as the water quality is suitable, goldfish can survive even if they are not fed for a month. In this process, goldfish will be fed with algae and plankton in the water, barely surviving. Although the goldfish is hungry, it does not mean that it can not be fed, always not fed, even if the goldfish is not starved to death, it will be malnourished, easy to get sick, the color of the body will become very bad, so that the ornamental of the goldfish becomes worse, so it is better to feed the goldfish regularly and quantitatively.
