1, feeding: koi do not know hunger and satiety, as long as there is food will always eat, so the novice must not feed koi too much food, to avoid their death or gastrointestinal diseases. In general, it is enough to feed 1-2 times a day, and the amount of each feeding can be finished in 5-10 minutes. Koi have a mixed diet and can eat many kinds of food. The common fish feed on the market can be fed to them.
2. Water quality: Koi likes clean and refreshing old water, but they can eat and pull, which is very easy to destroy the water quality, so breeders need to install circulating pumps for them, which can slow down the deterioration of water quality and reduce the frequency of water change. After the circulating pump is installed, the water can be changed 1-2 times a week.
3. Oxygen: Koi has a large demand for oxygen. In the process of feeding, if oxygen is found to be insufficient, it is necessary to immediately add oxygen or change water to ensure that the dissolved oxygen in the water is sufficient.
4. Fish tanks: Koi fish are bigger when they grow up, so it's better for breeders to choose some fish tanks with higher hardness to raise them.
should we pay attention to when raising koi? First of all, we should pay attention to the density. They grow faster and have a high demand for oxygen. If the density is higher, they will suffer from hypoxia. Secondly, we should pay attention to the environmental changes can not be too big, although the adaptability of Koi is strong, but they can not accept sudden changes in the environment, so breeders usually need to maintain the stability of the surrounding environment. Finally, we should pay attention to disease prevention, observe carefully at ordinary times, and treat immediately once we get sick.
