three koi? If a family wants to match and raise koi, the first thing is to ensure that they are similar in size, and the second is to choose different colors, so that matching and raising can be beautiful. Usually, it is common to raise red and white koi, Showa koi and golden koi together. The colors of the three are different, and the collocation can enhance the ornamental value. Others will replace the red and white koi with red-topped koi, because the whole body of red-topped koi is snow-white, with Showa and golden koi, the color contrast is more obvious. But if the breeder raises koi in the fish tank, he can choose German koi, light yellow autumn green koi, golden koi and so on, because the body of these kinds of koi will have some slight reflection in the water, which is more ornamental.
Koi raise a few good, depending on the size of the container, generally speaking, if it is raised in the fish tank, 80 cm of fish tank can be raised one. If you want to keep more than one, you'd better choose a large fish tank. Because the size of Koi is bigger when it grows up, and the situation of grabbing food is more serious. If it is raised in an outdoor fish pond, one side of the water can raise about 10-20 30 cm koi. If the area of the fish pond is larger, more fish can be raised. Koi have a high demand for oxygen, so breeders should try not to have too high feeding density, otherwise it will cause them to lack oxygen or jump into the tank.
