The common pike is not strict with temperature, generally it can survive at 20-30℃, and the water temperature of 24-27℃ is the most suitable for its growth. The optimum PH value of water is neutral water, and the pH value is 6.5-7.2. It is best to keep the dissolved oxygen at 5mg/l under the condition of artificial feeding. In addition, we should also pay attention to control the content of some toxins in water quality and make timely adjustments to provide a suitable water quality environment for common pike. Common pike is an ornamental fish that can tolerate rough culture. Many people may neglect management in the process of feeding. Even if the common pike can survive tenaciously, it will be listless and dejected. If you want the fish to live freely, you need the careful care of its owner. Adult fish have a strong sense of territory, and young fish may not have this sense. If young fish are raised in high density, they may not have territorial consciousness.
