, goldfish with poor water quality have their own adaptation range to the physical and chemical properties of water, and when the living environment becomes bad, they are easy to die. Like raising fish directly with unaired tap water, it is easy to die if the chlorine in the water exceeds the standard. Generally, tap water needs to be placed for two or three days or exposed to the sun for one day before it can be used. Moreover, if the water is not changed in time, too many secretions, too much carbon dioxide and too many fungi in the water can easily cause dead fish, so goldfish need to change water in time.
of water temperature goldfish is more sensitive to the change of water temperature, when the water temperature changes more than 5 C in a short time, it is easy to cause dead fish. Therefore, it is necessary to control the water temperature and not let the water temperature change frequently.
, the density of goldfish should not be too high. Excessive density will not only seriously affect the water quality, but also depress the range of goldfish and the uneven distribution of bait, resulting in the continuous death of goldfish.
feeding of goldfish bait must be chosen well, nutrition should be adequate, otherwise long-term feeding will easily cause goldfish physical weakness, resulting in death. In addition, when feeding, it is necessary to feed goldfish regularly and quantitatively, not too much at one time, otherwise it will easily lead to indigestion and death of goldfish.
