Is it suitable to buy koi in winter. The specific reasons are as follows:
1. The temperature is not easy to control: the temperature is low in winter and the temperature is not easy to control. Although Koi is a fish that does not require high temperature, if the temperature changes more than 3 degrees in a short period of time, they may die. If you buy koi in winter, you may die as soon as you take it home, which is caused by the large temperature difference. And the temperature of the fish tank at home may be different from that of the aquarium, which can also lead to discomfort or even death of Koi.
2. Feeding: In winter, when the temperature is low, the koi is inactive and does not eat. However, some shopkeepers will raise the water temperature in order to make the koi grow faster. When the temperature is high, the koi will have a large amount of activity, a high metabolism, and naturally eat more. But after buying the fish home, the water temperature of the fish tank at home can not reach the temperature of the aquarium, and the amount of feeding can not be controlled.
to buy koi first depends on the activity of koi, sink in the bottom of the tank or spirit can not be depressed, because this is generally sick fish. Secondly, look at the body shape, the back of the fish should be straight, the swimming posture is normal, the mouth position is correct, and the pectoral and pelvic fins should be symmetrical. Finally, look at the color, the color should be bright, gorgeous and natural, and the stripes should be clear.
