Without oxygen, small goldfish can also be raised, but the feeding density at this time must be lower than that under normal oxygen supply. Without oxygen, the oxygen content in the water will be reduced accordingly. As long as the number of goldfish is reduced, goldfish can still be raised normally.
without oxygen? In the absence of oxygen, if we want to raise goldfish normally, we need to increase the oxygen content in the living environment of goldfish by other means.
1. Reduce the feeding density: When the oxygen content in the water is reduced, the most direct way is to reduce the density of goldfish. In addition, reducing other sundries in the tank can also make the fish tank of the same size hold more water and increase the space for goldfish to move. This is also a disguised reduction in breeding density. Moreover, this can also reduce the difficulty of cleaning the fish tank.
2. Increase the frequency of water change: change more water when artificial oxygenation is not available, or add new water to improve the dissolved oxygen in the water body. The same principle, you can also use two fish tanks to raise a tank of goldfish, the same size of the fish tank, the goldfish can change the tank regularly.
3. Add aquatic plants: Some aquatic plants can be planted in the tank. According to the size of the fish tank used for feeding, you can choose the appropriate aquatic plants. In the fish tank, the aquatic plants will produce oxygen through photosynthesis and continuously increase oxygen for the water body.
