Extended data:
1, fish farming should first pay attention to the problem of water quality. Many people directly change tap water to raise fish, but they don't know that tap water is very harmful to fish. Fresh tap water contains a lot of hypochlorous acid, which has bleaching effect and will lead to discoloration of red fish. Hypochloric acid decomposes under light conditions, so whenever we want to change water for fish, we should think about putting tap water in the sun for half a day in advance.
2. Fish farming can't change water often. Changing water too often will lead to the death of fish. If the common fish tank is replaced every 3-4 days, it depends on the degree of water pollution.
At the beginning of fish farming, you need to add a little bit of raw salt to the water, not too much. This is good for the disinfection of water supply and the treatment of fish, but not putting salt often will lead to the dependence of fish, and putting salt at a critical moment has no effect.
4, don't feed the fish too much food, feeding too much will cause the fish to eat a lot and die. Usually feed fish at home about once a day 1-2 times.
