What should I do after the fish dies?
2. If there are few fish in the aquarium, new fish can be added, but it should be noted that tropical fish and temperate fish cannot be placed in the same aquarium at the same time, otherwise it will be difficult to control the water temperature in the aquarium.
At the same time, we should pay attention to:
1, the number and types of fish farming and the size of fish tanks are also very particular. As for stocking density, rectangular aquariums in China are not suitable for raising more because of their small size, so as to ensure that Feng Shui fish have enough room to move in the aquarium.
For example, in a container with a length of 40 cm, a width of 25 cm and a height of 30 cm, you can raise 6 to 8 small goldfish with a length of 5 to 7 cm. For example, a round glass jar with a diameter of 26 cm and a height of 13 cm can raise 4 ~ 6 small goldfish with a diameter of 4 ~ 6 cm.
2. Pay attention to adjusting natural factors such as temperature and light to make it suitable for the growth of fish. In the process of fish farming, if fish die, we should find out the causes and factors of fish death and find out the treatment methods according to the source.
First of all, it is necessary to judge whether the fish tank water is short of oxygen. If a fish jumps out of the water to breathe oxygen, it is hypoxia in the fish tank. It is suggested to set an oxygen pump in the fish tank to strengthen the oxygen in the fish tank water and reduce the death of fish due to lack of oxygen.
At the same time, we should also pay attention to the ventilation performance of the fish tank to avoid direct sunlight, otherwise the fish will die of suffocation due to lack of oxygen.
Secondly, it is necessary to observe the sudden change of water quality and water temperature in the fish tank to ensure that the environment in the fish tank is suitable for fish to survive. Pay attention to the cleanliness of fish tank water at ordinary times, and clean up the residual fish food and excrement in time.
Adjust the frequency of changing water according to the needs of fish. Changing water too often can also lead to fish's inadaptability. The water surface and the fish tank can't be in the same line, otherwise the water surface will be too full, causing the fish to jump out of the ground and die.
Extended data:
Although goldfish is an omnivorous fish completely domesticated by human beings, it is the same as other fish such as crucian carp. Whether the feed selection is reasonable and the feeding is correct can directly affect the growth and development of goldfish, the depth and brightness of color, the appearance and fullness of traits, the number of eggs laid, the hatching rate and the disease resistance of goldfish.
Goldfish feed must be rich in protein, fat, carbohydrates, vitamins, a certain amount of inorganic salts and trace elements.
It is best to feed with 0.5% saline. There is chlorine in tap water, so it should be exposed to the air for half a day to remove chlorine, or washed with commercially available neutralizing solution or vitamin C candy for four to five times to neutralize toxicity. [2] There are many harmful substances in well water, so we should also pay attention to them.
In addition, among goldfish breeders, there is also a breeding method called "green water", which controls the number of phytoplankton and algae in the water tank to keep the water a little transparent green tea color.
Using phytoplankton in edible water can make goldfish more colorful and alleviate the drastic change of water quality when changing water. However, if it is not properly managed, the excessive reproduction of phytoplankton will make the green water too thick and easily cause goldfish diseases.
