What are the habits of a goldfish? What are the ecological habits of goldfish?

1. Goldfish have a wide range of eating habits, which are omnivorous fish based on animal bait, and require food rich in protein, fat, carbohydrates, various vitamins, inorganic salts and trace elements. This is the necessary material basis for the growth and development of goldfish.

2. Goldfish are ectotherms, and their body temperature can change with the water temperature, but their body temperature cannot change with the water temperature endlessly. Excessively cold or hot weather will affect the growth and development of goldfish. The optimal living environment temperature for goldfish is 22 24, also known as the optimal temperature for growth.

Goldfish are extremely vigorous in seeking bait at the optimal temperature, with the fastest growth rate, increased excrement and oxygen consumption, and its physiological requirements are the highest. In the actual feeding, during this period, the method of mixing water or changing the water once every 3 days is adopted, so that the goldfish always maintain the best bait state with clear water and sufficient oxygen.

Goldfish in the water temperature of 15 18, the bait is moderate, the activity is normal, the water quality has the longest shelf life, it is the easier stage of goldfish management.

3. The personality of the goldfish is very gentle, and there will be no phenomenon of big goldfish chasing small goldfish. In addition to the breeding season, goldfish of various shapes and colors can be mixed together.

Habits: Goldfish is ectothermic, and all its activities are closely related to changes in water temperature. Most of the goldfish's activities consist of foraging for food in the water, and they live in peace and have no habit of occupying territory.

At goldfish farms, it is common to see goldfish feeding along the edge of the pond at dawn. When the keeper approaches, they will swim forward in unison, commonly known as begging for food, and then put the bait, and they will immediately swarm to grab the bait. When the water temperature is above 15 degrees Celsius, the goldfish's foraging activities are more active, when the water temperature exceeds 30 degrees, the goldfish will stop feeding, when the water temperature is lower than 5 degrees, the goldfish's foraging activities are significantly reduced, when the water temperature is 18-25 degrees, the goldfish's appetite is the most vigorous, and the growth and development of the fish body is also the most rapid.

Biological habits: (1) The most suitable water temperature for goldfish to live in the living environment is 20 28, in this temperature range, goldfish swim lively, have a strong appetite, have a strong physique, and have bright colors. The dissolved oxygen content of goldfish pond water should reach more than 3mg l, because at this time, the goldfish digest and absorb the feed better, and the feed coefficient is also lower, which is conducive to the normal growth of goldfish.

Goldfish are in the optimal range, while fish eggs and larvae are better. (2) Habit: Goldfish like to eat fish and insects, and also like to eat other aquatic plants and other plant feeds, and are typical omnivorous fish. Growth and developmentGoldfish are sexually mature when they reach about 1 year of age, reproduce once a year, have the strongest fecundity at 3 years of age, and gradually decline after 5 years of age.

The lifespan of a goldfish is generally considered to be 6-7 years old.

1. Little goldfish are lively by nature, like to swim, like to jump. 2. Little goldfish like to grow in the sun, and the body will become more showy. The little goldfish likes to eat, and under the right water temperature, the goldfish will eat non-stop, and it is a very edible ornamental fish.

3. Small goldfish like to eat fish insects, shrimp and other meaty foods, when there is no meat food, you can eat algae, moss and other food, when there is no food, even soft mud will swallow.

Goldfish is one of the world's three famous ornamental fish, originating in China and has a history of more than 1,700 years. Goldfish has a beautiful body and a wide variety of species, its body color is red, yellow, blue, purple, black, white, two-color, three-color, five-flower, etc., its body shape has lion head, high head, blister, dragon eye, pom-pom, pearl scales, butterfly tail, tiger head and so on. Goldfish has a strong ability to adapt to water temperature, but can not adapt to the drastic changes in temperature, its suitable water temperature is 18-26, and too high or too low temperature will affect the feeding and growth and reproduction of goldfish.

Goldfish prefer weakly alkaline water, and the pH value of the water body is more suitable.
