1. Water temperature requirements p>
The water temperature where goldfish can survive is 0-39℃, but the most suitable water temperature for their growth is 20℃-28℃.
Within a comfortable water temperature range, the higher the temperature, the faster the goldfish’s metabolism, the better the appetite, and the faster the growth and development. Therefore, it is generally recommended to control the water temperature at 26-28 ℃, which can enhance the activity of goldfish, enhance the physique of goldfish, and keep goldfish in bright colors.
In addition, the water temperature in which the goldfish is raised should be kept relatively balanced. If the mutation of the water temperature exceeds 7-8℃, the immunity of the goldfish will be affected. May get sick. If the water temperature mutation is larger, it is easy to cause the fish not to eat, and it may even directly lead to the death of the goldfish.
2. Dissolved oxygen content
Oxygen content is the margin A necessary condition for fish to survive normally in water, the dissolved oxygen requirement of goldfish is usually above 5mg/L. May die.
3. Carbon dioxide content
even if the oxygen content is sufficient High, if carbon dioxide levels are too high, it can also cause goldfish to have difficulty breathing. Under normal circumstances, if the carbon dioxide content in the water exceeds 60mg/L, goldfish cannot develop normally, and the source of carbon dioxide is mainly the respiration of goldfish and other plankton, and the oxidation reaction of goldfish excrement. Therefore, pet owners need to control the density of goldfish, clean up the feces of goldfish regularly, and avoid excessive carbon dioxide content.
4, pH?
strong>
Goldfish can live in water with a pH of 5.5 to 9.5, but the most suitable pH for survival is between 7.5 and 8.5. If the PH value is too high, the active value of goldfish will decrease, the appetite will gradually decrease, and the growth rate will slow down or even stagnate.
How to adjust PH value?
When the pH value of the water body is low, you can add an appropriate amount of carbonate to improve it, or you can put a small amount of coral sand in the water to improve the overall Alkaline. If you feel that the first two methods are more troublesome, you can also go to the aquarium store to buy a PH value adjuster.
When the pH value of the water body is high, you can add an appropriate amount of dihydrogen phosphate to reduce it. If there are aquatic plants in the water tank, you can also add some sinking wood or carbon dioxide to lower the pH.
5. Water hardness requirements
The hardness of water is Refers to the content of metals such as calcium ions, magnesium ions, and iron ions in the water. If the content of metal ions is too high, the water quality is hard. On the contrary, the content of metal ions is low, which indicates that the water quality is soft.
Generally speaking, soft or hard water quality will not have a great impact on goldfish, because goldfish can adapt to different water quality, but the water quality cannot suddenly Too much change, and if you put soft-water-adapted goldfish in hard water, the goldfish are likely to die because they can’t adapt. Therefore, the newly bought goldfish should use the partial water exchange method. Now all the fish in the aquarium are picked up, and then all the water in the aquarium is turbid. After waiting for settling, use a siphon to suck out 1/1 of the waste water in the center and bottom. 3 or so, and then add new water.
The above is about the requirements of goldfish for the living environment and some tips for raising them. Although goldfish are relatively easy to raise fish, their vitality is indeed It is not as tenacious as we imagined, so everyone should understand the corresponding common sense in advance during the breeding process. When the goldfish is abnormal, the specific problems can be checked out in time.
