First of all, when you want to raise koi, you need to prepare appropriate equipment. First of all, the fish tank, because Koi is a large ornamental fish, so the fish tank needs to be large enough, otherwise the space will be insufficient. Specifically, the depth above 0.8 meters is better, and the length around 1.2 meters is better. Then there are some other devices in the tank, such as filters, which can clean up the water when it is dirty. There are also some heating rods, oxygen pumps and so on, which can increase the water temperature and oxygen.
1, to ensure water quality: Koi culture in the fish tank, water quality is very important. Compared with farming in fish ponds, the water in fish tanks is easier to get dirty, so it needs to be changed regularly. Generally speaking, when the temperature is relatively high in summer, water has to be changed every three days or so. After the water is dirty, it must be replaced in time, otherwise it will affect the growth of Koi.
2. Reasonable feeding: It is also very important to feed the koi in the fish tank at ordinary times. You can put food in the tank once or twice a day, once in the morning and once in the afternoon. Koi is an omnivorous animal, can be fed plant feed, can also be fed animal feed, but it is best to combine the two, so that nutrition will be more abundant, it is not easy to make them produce anorexia.
3. Appropriate illumination: Furthermore, it is the problem of illumination. The goldfish in the fish tank can receive astigmatism for a certain period of time every day, which can play a role in sterilization. However, in the summer, if there is direct light shining into the fish tank, you have to block it.
