Betta fish don't need oxygen under normal feeding, because their demand for oxygen is not very high. As long as the breeder can change water regularly, the oxygen in the new water can meet their demand for oxygen. In addition, they have auxiliary respiratory organs. When there is less oxygen in the water where they live, they will swim to the water and use their auxiliary respiratory organs to breathe oxygen in the air. Therefore, in the case of growing and feeding, the breeder does not need to give them oxygen. However, when the feeding density is too high, it is also necessary to install an oxygen pump to ensure sufficient oxygen in their water.

It is better to heat them when raising betta fish artificially. Because they are tropical fish, they like higher water temperature. Heating can make them grow better and grow faster. However, compared with Thai betta, Chinese betta can adapt to a wider range of water temperatures. Chinese betta can accept temperatures above 6 ℃. If Chinese betta is cultured, you can choose not to heat it. If Thai betta fish are farmed, it is best to heat it. Especially after entering winter, the temperature is relatively low, and the temperature changes greatly, so it may affect their lives without heating. In addition, if breeders want betta fish to breed, they'd better heat them. Because the temperature is low, it will also affect their growth and development.
