There are six goldfish in my home. Do you need an oxygenator?

If the average goldfish is not too big and the number is not too much, there are only six goldfish you mentioned, and there is no need to increase oxygen.

It is a good idea to increase the oxygen in the water, which is also an important step to feed goldfish. By raising some aquatic plants to increase the oxygen in the water, it can only be realized under the condition of sufficient light. If your fish tank doesn't have enough light (illumination) to illuminate plants, aquatic plants will not only release oxygen, but also absorb oxygen to release carbon dioxide, which will not only make goldfish enjoy more oxygen, but also will not bring harm to water quality. Aquatic plants will also fail and die, because without enough light, they can't produce the nutrients they need. For example, besides raising aquatic plants in water, there are many ways to increase oxygen and reduce consumption. If possible, buy a strainer, which can both filter and aerate, killing two birds with one stone. At present, most filters have their own oxygenation system.

There are many reasons for the death of fish just bought. Everyone who raises fish for the first time has the experience of dead fish. Generally speaking, goldfish can be raised well as long as it is carefully raised, properly managed, with fresh bait, fixed quality, quantitative and regular feeding, attention to stocking density, control of water temperature changes and good water quality.
