First of all, we should pay attention to the density of fish farming. The density of fish farming should not be too high, otherwise there will be too many fish, and they will easily rub each other, and the oxygen consumption will also increase, which is harmful to their health.According to the difference of fish body shape, choose the number of good breeding, small fish can be more, big fish should be less.
Fish live in water, so the situation of water also determines the health of fish.If the water quality is not good, it will also increase the probability of fish illness, and even lead to their death.In order to maintain the water quality, a filter device is usually placed in the fish tank, which can make the water flow and reduce the rate of decay.You can also change the water regularly, extract a quarter of the old water, and then slowly inject the new water.
Although the fish is relatively hunger-tolerant, it cannot be fed for a long time. It is usually fed two to three times a day. In this way, feeding several times and a small amount can not only meet its growth needs, but also will not lead to deterioration of water quality, which is very helpful to the health of the fish.In addition, feed should also pay attention to replacement, so as not to be picky about food.
Fish farming needs to control the temperature, especially for tropical fish, the water temperature should be kept between 20-30 ℃, so that it can grow healthily.If the temperature is too low, the resistance of the fish will decrease, and they will have no appetite and eat little.
