for Luohan fish? First of all, we should choose a reasonable water source. Because Luohan fish is a kind of freshwater fish, we can raise them with river water or tap water. River water is the most suitable water for their growth, which contains various nutrients suitable for the growth of Luohan fish, but this kind of water is difficult to obtain. Tap water is obtained from natural water through sterilization and disinfection. It is easy to obtain and clean. It is more suitable for fish farming. However, attention should be paid to chlorine removal before use. As a toxic gas, chlorine will affect the health of Luohan fish.
Secondly, to control the amount of water, in general, each time a quarter of the original water can be replaced. If you change too much water, it will affect the water quality. However, if the water in the fish tank is too bad, replacing a quarter of it is far from the effect of cleaning the water quality, then half of it needs to be replaced. When changing water, we should also pay attention not to let the temperature of the new water differ too much from the original water temperature in the fish tank.
