If fighting fish is oxygenated, it will not be killed under normal circumstances. Because they live in water, they need a certain amount of oxygen to survive, and they generally won't die under normal oxygen. Moreover, they have low requirements for the environment and strong adaptability, so even if they are oxygenated for too long, there will not be too many problems. Although oxygenation for too long will not affect their lives, it will still affect their health to some extent. When raising betta fish artificially, the time of oxygenation can be decided according to their living space and feeding density. This can not only ensure that their oxygen is sufficient, but also prevent excessive oxygen from affecting their health.

The oxygenation time of betta fish can be determined according to their density. If the breeding density is normal, the breeder can choose not to be oxygenated or to be oxygenated for 1-2 hours every day. Because the demand for oxygen in betta fish is not high, and they also have auxiliary respiratory organs, breeders can choose whether to use oxygen according to their actual situation.

If the density of betta fish is high, the breeder needs to get oxygen for 3-5 hours every day, so as to ensure that they have enough oxygen. If the feeding density is very high, it is best to choose 24-hour oxygenation.
