? Goldfish are highly oxygen-consuming fish, and they generally need oxygen to raise them. If you want to raise them without oxygen, you need to pay attention to the following points:
1. Water quality: When raising goldfish, the breeder should try to use sunning water, so as to avoid causing harm to them. In addition, try to keep the water changed every two days, and the amount of water changed each time can be controlled at a quarter, which can help improve the oxygen content in the water.
2. Space: When raising goldfish, choose a slightly larger fish tank, which can provide them with a sufficient swimming space. In addition, there are many water bodies in the large fish tank, in which the fish are not easy to suffer from hypoxia.
3. Food: When feeding food, the breeder should follow the principle of eating less. The amount of feeding each time should not be too much, so as to avoid the remaining food decaying in the water, thus consuming oxygen in the water.
4. Aquatic plants: You can plant some aquatic plants in the fish tank, which can also provide a proper amount of oxygen.
