Black koi fish breeding
Now that we have talked about how to breed black koi fish, let's talk about the environment that black koi fish needs. Black koi fish is nothing special to the environment. The optimum water temperature is 22~28℃, and the optimum PH value is 7.2~7.5 (I saw it in Baikou). It likes to live in water with slightly lower hardness, but it also accepts water with higher hardness. But not too hard. There is a high demand for water quality, which requires that the surface should be clean and the contents of nitrate and ammonia nitrogen in water should be controlled.
In addition to the above points, it is necessary to choose a reasonable feeding density, a powerful filtration system and a reasonable and correct diet in koi fish. Everyone knows that koi fish can eat and pull. If the feeding density is too high, the limited filtration system cannot completely remove impurities and nutrients from the water.
Many people think that big fish tanks have grades, but they are not. If the fish tank is too big, it is too big to be suitable. People's gas field will be sucked away by the fish tank, and the humidity is too heavy, which is very unfavorable for gas gathering. The size of the fish tank is about a quarter of the width of the living room.
