, the water can not be heated directly, which will make the water temperature change dramatically and do great harm to the health of the fish. If you want to raise the water temperature, you can use a heating rod or put a bottle of hot water in it, which can also slowly raise the water temperature. It should be noted that the daily temperature rise should be controlled within 2 degrees Celsius, if the temperature difference is too large, the fish can not adapt.
of low water temperature on fish? 1. Loss of appetite: Fish are poikilothermic animals, and their body temperature will change with the external temperature. Therefore, their metabolic level is closely related to the environment. When the temperature is low, their appetite will also decrease, and they do not eat much. Generally, people with fishing experience have more feelings about this, and fish are not easy to open their mouths in low temperature season.
2. Lack of vitality: In addition to affecting appetite, low temperature can also cause fish to have little vitality and swim less in the water. If the temperature is higher, fish will become more active and swim faster.
3, easy to get sick: Low temperature can also make fish more likely to get sick, many diseases are suffered in the low temperature season, such as white spot disease, Saprolegniasis, etc. When the temperature is kept at a high level, the resistance of fish can also be improved, and the metabolism is vigorous, the possibility of illness will be reduced.
