The general habit of crayfish is that they like shade, humidity and meat, especially liver, but they also eat vegetables and rice when they are hungry. Crayfish likes to stay in the dark corner. If you don't believe me, if you put it on the ground, it must crawl under the sofa and bed, and it doesn't like to stay in bright places. If you put it in the sun, it will try to hide in a place with less sunshine. If you put it in a basin, it will climb and climb until it stands up completely, and then it will fall on all fours. But it will continue to climb after turning over. This animal is very persistent. Crayfish is easy to raise. Eat meat at noon every day: pork (pure lean meat, fat meat is not eaten, crayfish with some blood is preferred) or animal liver (fish liver and pig liver are ok). Brush it once a day with a small brush as a bath and use some soap. If it is sunny on the weekend, put it on the balcony for a while and take it back after a few hours. Crayfish don't eat much after the end of October. It depends on the temperature to enter hibernation. If the temperature is high, hibernation will be delayed, and vice versa. In order to let crayfish hibernate well, you must ensure nutrition in summer and autumn, which is basically enough and the meat used is good. Crayfish don't eat or drink after hibernation. At this time, put it in a cardboard box. Put some newspapers, rags and foam in the cardboard box. When it is cold, it will naturally get into the cloth, and then put the box in a warm room. During hibernation, you should take it out and put it in warm water. The so-called warm water is water that doesn't feel cold. The temperature should not be too high. Then feed something and get some sunshine. Put it back and continue to hibernate. Crayfish is easier to raise than other animals, and it is also very lucky. It doesn't matter even if you forget to feed occasionally. Because if crayfish are in the wild, they only eat once every half a month or even a month on average. Crayfish is an amphibious animal, so the place where crayfish live is humid, but there should not be too much water. A more convenient way is to put it in your own pool. Or a more advanced method is to get a water tank, half of which is water and half is dry land. Water, not too deep, not more than the crayfish back. But I recommend the former, which is convenient and convenient, and crayfish are also happy. It is convenient to feed and clean. If you want to keep the crayfish wild, get some live fish and shrimp, which will basically take one noon to kill.
