Lili fish do not need oxygen very high. Whether breeders should give them oxygen depends on the size of fish tanks and the density of feeding. If the fish tank where Lili fish live is relatively large, and the breeder has installed a circulating filtration system for them, it is ok to change water regularly without oxygen.

If Lili fish live in a small fish tank and the breeder does not install a circulating filtration system for them, then the breeder needs to install an oxygen pump for them to ensure sufficient dissolved oxygen in the water. Because the water body is small, the water quality is easily polluted. When the water quality in the fish tank is poor, the oxygen in the water will decrease sharply, so the breeder needs to give them oxygen.

If it is a normal feeding density, the breeder can give them oxygen for 2-3 hours every day. Because their demand for oxygen is not particularly high, they can meet their daily needs by taking oxygen for a few hours every day. If the density of feeding is too high, the breeder can decide the time of oxygenation according to their density. If the feeding density is very high, the breeder needs 24 hours of oxygen. Of course, if the breeding density is low and the circulating filtration system is installed, it is ok not to give them oxygen.
