Whether lamp fish need oxygenation is best determined according to their feeding density. If the density in the fish tank is normal or low, and a filtration system is installed, it is ok for the breeder not to oxygenate them. Because the density in the fish tank is low, as long as the water is changed regularly, the dissolved oxygen in the water is enough for them to absorb. Moreover, filters can also add a small amount of oxygen, and their demand for oxygen is not very high, so a small amount of oxygen is enough for them to absorb. If the density in the fish tank is too high, the breeder needs to give them oxygen. Because the density in the fish tank is too high, the dissolved oxygen in the water will be insufficient. If they are not given oxygen, they may die because of lack of oxygen.

Lamp fish need to be heated. They are tropical fish and like higher water temperature. Especially in most parts of China, the temperature in winter is relatively low. If breeders have the conditions, it is best to install a heating rod to keep the water temperature between 22-26 ℃. In a stable range, their growing environment will be more comfortable and their physique will become stronger. After entering summer, breeders don't need to heat them. Because of the high temperature in summer, even if it is not heated, it can meet the needs of their normal growth.
