? When the water temperature is 3 degrees, the goldfish will feel uncomfortable, the color of the skin will fade, the resistance will decrease, the probability of illness will increase, and there will be the possibility of freezing to death. When the water temperature is below 0 C, they are easily frozen to death.
In fact, goldfish is a kind of fish that is easy to raise. It is not delicate. It has a wide range of adaptation to water temperature. It can survive at 0-39 C water temperature. This is mainly because of its variable temperature constitution, which can be adjusted according to the water temperature. If you want to feed a healthy and long-lived goldfish, the water temperature should be constant at 18-26 C. At this temperature, it is the most suitable for survival and the fastest development.
in winter 1. Stabilize the water temperature: The water temperature in winter should also be stabilized at 18-26 ℃. It is better to put the fish tank indoors, so that the temperature is better controlled and the fluctuation of the water temperature is not large.
2. Ensure the water quality: In winter, the water quality does not deteriorate so fast, and the bacteria grow slowly, so there is no need to change the water regularly. However, when the water is found to be turbid and smelly, the water needs to be changed, which means that the water quality has deteriorated. Moreover, when the goldfish has a floating head and drinks water in big gulps, it is also necessary to change the water in time, because at this time the water is generally anoxic.
3. Prevention of fish diseases: Prevent white spot disease and saprolegniasis in time. In winter, the water temperature generally fluctuates greatly, so it is necessary to stabilize the water temperature and ensure that the water body is clean. Once fish diseases are found, medication should be taken immediately.
