winter in the courtyard fish tank? Because the courtyard fish tank is placed outdoors, it will inevitably cool down in winter. In this way, the fish inside will be affected, ranging from loss of appetite to freezing to death. In order to avoid this situation, we need to do a good job of keeping warm. Usually, the fish tank should be buried in the soil, and the part exposed to the surface can be wrapped with a quilt, but not completely closed, otherwise it will lead to airtightness, and a little more water should be added to the tank.
should we pay attention to when raising fish in winter? 1. Pay attention to the temperature: First of all, we should pay attention to the temperature when raising fish in winter. For wide-temperature fish, the water temperature should not be too high, and it can be kept above 5 degrees Celsius. But if it is a tropical fish, the temperature must be controlled at about 20 degrees Celsius, long-term in a low temperature environment, the fish is likely to freeze to death.
2. Pay attention to feeding: Fish are poikilothermic animals, so their vitality will be affected by temperature, and appetite is no exception. With the coming of winter, the temperature gradually decreases, and the feeding should be reduced a little, so as not to turn the food it can not eat into residual bait, thus polluting the water quality.
3. Pay attention to changing water: fish farming needs to change water, and the cycle of changing water is often related to the season. In summer, when the temperature is high, the water body is easy to deteriorate, so it is necessary to change the water frequently. In winter, it is not necessary to change the water too frequently. It is no problem to change the water once a week or two. In addition, it is better to keep the same temperature before and after changing the water.
