1. How to choose Showa koi fish 1. Look at the head: The first thing to choose Showa koi fish is to look at the head. Usually, the head of a good koi fish will have large erythema or black spots, and the color quality is uniform and clear, and the color is also very gorgeous.
2, look at markings: In addition to looking at the head, but also look at the markings on the body, preferably white, accounting for about 20% of the whole body.
3, look at the fins: Also look at its pectoral fins, which should be moderate in size, preferably one quarter of the body length, and preferably black in color.
2. How to raise koi in Showa1. Change water regularly: When raising koi, we should pay attention to changing water first. This kind of fish is closely related to carp, and the requirements for water quality are relatively broad. However, changing water regularly to maintain water quality can also reduce the possibility of fish getting sick. Usually, it should be changed every five to seven days, and the water should not exceed one third of the total water volume every time.
2, pay attention to oxygenation: Koi is a large ornamental fish. Because it grows large, it consumes more oxygen, so it is necessary to pay attention to oxygenation. In the daily feeding process, it is best to use an oxygen pump to oxygenate 24 hours a day and turn it on at night, so as to prevent fish from floating.
3. Proper feeding: Because koi carp has no stomach, it digests quickly, and it can hardly feed enough, so it will eat as much as it feeds. However, this is not good for the health of fish, and it is easy to get enteritis and other diseases. Moreover, a large amount of residual bait falls in the water, which will also pollute the water and cause fish to get sick. In the daily feeding process, pay attention to a small number of times, and ensure that each feeding is finished within 5 minutes.
