There are many kinds of fish, and different fish die at different times after leaving the water. For some deep-sea fish, they will die immediately after coming out of the water. Cold water fish in streams can only live for about 10 minutes at room temperature after leaving the water, and many freshwater fish will die within 3-5 hours after leaving the water. Like black fish, catfish and other vigorous, can be out of the water for 12 hours. African lungfish and loaches can live for months in dry soil.
1. Water temperature and water quality: Fish can't live without water, and whether the water temperature and water quality are good or not determines how long the fish can live. For cold-water fish, they have a wide range of adaptation to water temperature and do not have to worry about survival, but tropical fish are different, water temperature must be controlled between 20-30 C, so as to survive. For different fish, the requirements for water pH and hardness are also different.
2. Regular feeding: In order to make the fish grow better, it is necessary to feed the fish at ordinary times. According to the difference of fish feeding habits, we should choose delicious feed, not only feed a single feed, often change and use can avoid its picky eating, but also supplement more abundant nutrition. It should be noted that the feeding amount should not be too large, so as not to support the stomach.
3. Pay attention to changing the water: Fish farming must change the water, because the water quality will change over time. In the short term, you may not feel anything, and over time, it will seriously affect the health of the fish. It is usually changed once a week, and about a quarter of the total water volume is changed each time. If the filter system is good, it can be changed once half a month.
