to raise fish in

a water tank? Generally, you don't need oxygen to raise fish in a water tank. This kind of tank holds more water, raises fewer fish, and is a slightly smaller fish, plus the water surface and air contact, so there is little hypoxia. In addition, this kind of tank is relatively deep, the bottom pressure of oxygen is high, and there may even be no bubbles. If some aquatic plants are kept in the water tank, oxygen can also be produced through photosynthesis.

2. What are the benefits

of oxygenation in fish tanks? 1. Maintaining water quality: The high oxygen content in water is helpful to the maintenance of water quality. It is mainly divided into two aspects, on the one hand, oxygen promotes the growth and reproduction of nitrifying bacteria, so as to better transform ammonia nitrogen. On the other hand, it can inhibit the growth of anaerobic bacteria and prevent the deterioration of water body.

2. Good for breathing: The main purpose of oxygen is to make the fish breathe better. Although this animal lives in the water, it also needs to absorb oxygen in the water. In order to maintain the dissolved oxygen in the water, it needs to add oxygen to the water. Of course, a certain amount of oxygen can also be increased by means of water change and filtration.

3. Accelerate growth: The higher the oxygen content in the water, the more vigorous the fish will be, which will also promote their growth and accelerate digestion. Of course, there are many conditions for growth, besides sufficient dissolved oxygen, there are also water temperature and feed richness.
