The optimum temperature for the growth of goldfish in 20-28 degrees Celsius, this water temperature, goldfish growth and development of the most vigorous, food, excretion and oxygen consumption are the largest, this time the goldfish is the most bright and lively.

The goldfish is a thermotropic animal, the water temperature adaptability is relatively strong, the body temperature changes with the water temperature, in the 0-39 degrees Celsius water temperature can survive. But the goldfish can not adapt to dramatic changes in water temperature, the temperature rises sharply or falls more than 5 degrees Celsius, may endanger the life of the goldfish.

The goldfish is more adaptable to the water quality, has a certain ability to tolerate dirty water, but also more resistant to acid and alkali, acidity and alkalinity (pH? value) in the water quality of 5.5 ~ 9.5 can survive. Alkaline water is more suitable for goldfish to grow, but the alkalinity should not be too high, and the pH value should not exceed 8.5.

Expanded Information:

The goldfish is an omnivorous fish completely domesticated by human beings, but it is the same as other fish such as crucian carp, whether the feed is selected reasonably, whether the feeding is correctly can directly affect the goldfish's growth and development, the depth of the color and the degree of vividness, as well as the number of spawning, hatchability and the resistance to diseases of the goldfish.

So, if the feed is chosen correctly, it can directly affect the growth and development of goldfish.

So, in the goldfish feed, must have nutritious protein, fat, carbohydrates, various vitamins and a certain amount of inorganic salts and trace elements.

Other conditions are exactly the same case, where the daily feeding of fresh and live redworms, the fish body growth and development of large, especially the lion's head, blisters and other features are more developed, which may be redworms contain a large amount of animal protein, fat, carbohydrates and other nutrients rich in the cause.
