Fish can use mineral water.Mineral water has certain minerals, the hardness of the water body is more appropriate, and it is also very good for fish farming.However, because fish farming needs to change water regularly, the cost of long-term use of mineral water is still relatively high, and may also increase the content of impurities, so it is best to choose tap water, before using to dry for a period of time, so as to remove chlorine.
1. Water temperature: First of all, pay attention to the water temperature when raising fish. Not only tropical fish have requirements for temperature, but also eurythermal fish have requirements for temperature. If the water temperature is too low, the activities of fish will be limited and become less energetic.At the same time, it will affect appetite, and it will not grow well if you don't eat.
2. Water quality: Good water quality is very helpful to the health of fish.In addition to always turning on the filter, change the water regularly, usually once a week, a quarter of the time.It should be noted that the new water must be dried before it can be used, and the water temperature should be the same as the old water.
3. Dissolved oxygen: The oxygen content in the water will also affect the breathing of the fish, so it is best to prepare an oxygen pump, so that it can be given oxygen. It can be turned on for 2-4 hours every day. In case of continuous rainy weather, it needs to be turned on for an additional period of time, so as to ensure sufficient oxygen.
