1. Why don't you raise a single fish but not a double fish Because some fish are too fierce, raising two fish will fight, so it is only suitable to raise one fish. However, many smaller fish are gentle in temperament, so it is no problem to raise more fish. How many fish can be raised in the fish tank depends on the specifications of the fish tank and the size of the fish. Usually, if the fish tank can hold one liter of water, it can raise one centimeter of fish. The bigger the fish tank, the more fish it will raise.
2. What are the precautions for fish farming1. Feeding: Feeding should be paid attention to first in fish farming. Usually, you should feed it two or three times a day, don't eat too much each time, and ensure that the fish can be eaten within 3-5 minutes. According to the different feeding habits of fish, the choice of feed types is different. Carnivorous fish should be fed meat, and herbivorous fish should be fed vegetarian.
2. Change water: In order to ensure the health of fish, change water regularly. The cycle of water change is not fixed, and it is usually determined according to the maintenance of water quality. If the water quality deteriorates rapidly, it is necessary to change water frequently. In addition, when changing water, we should pay attention to controlling the water temperature, and the temperature should not fluctuate greatly, so as not to stimulate fish.
3. Oxygen: For some larger fish, the level of dissolved oxygen in water will also be very important, which will affect the health of fish. Under normal circumstances, it is necessary to prepare an oxygen pump for oxygenation, and it is best to turn on the oxygen pump all day, so as to avoid the occurrence of oxygen-deficient floating head.
