Koi is a common ornamental fish, but also a very long-lived fish. If the living environment around it has been in a more appropriate state, then its life span will generally be 60-70 years. In addition, there are also much longer life of Koi, for example, there are also records that the life span of some Koi can reach 200 years, but this Koi is still in the minority. For Koi raised in the family, how long they can survive depends on whether various factors in the environment are suitable for their growth and development, density, feeding, water quality and other factors will affect their life span. If these are kept suitable, then the life of Koi will be longer. However, generally speaking, the ornamental value of Koi is only about 15 years, after 15 years, even if they are still alive, but their ornamental value will be relatively low.
1, density: Koi need to provide adequate space, so the number of Koi do not be too much, the fish tank can not be too small.
2. Feeding: Reasonable feeding is very important if you want the koi not to die easily. Feeding can not be too much, can not be too little, feeding once or twice a day, each feeding so that Koi in seven or eight full is the most appropriate.
3, water quality: water quality has been in a clean state, koi is not easy to die. Therefore, in order to achieve this goal, it is necessary to change the water regularly. Water needs to be changed at least once a week, and if the water gets dirty quickly, it has to be changed once every three or four days. When changing water, the speed is also slow, and the water temperature should not change too much.
4. Illumination: a part of green plants can be cultured in the fish tank by the way, and then a certain amount of illumination is provided every day, so that they can carry out photosynthesis.
5. Treatment: If you want the koi not to die easily, you have to treat them in time after they get sick. Especially if they get infectious diseases, they can easily die if they are left alone.
