They really like to eat a lot. Animals include planktonic fleas (usually fish worms and red worms), water worms (nematodes), calluses, cooked egg yolks, earthworms and insects of appropriate size ... Plants include: yellow algae, diatoms, green algae, radishes, duckweed, aquatic plants, bran, bean cakes and noodles. Your goldfish must not taste so good, right? It's okay, Kim. Fish are not very picky when they arrive. It's okay to eat the same food all your life. As long as it is alive, it will eat with relish.
It is generally believed that feeding live food (such as red worms, water worms, etc. ) is the best, goldfish will grow quickly. Feeding dry worms or artificial feed is an expedient measure, and there is no way out. However, the author has kept goldfish for nearly 20 years, but he has come to the opposite conclusion. If you are a goldfish lover and keep it in an indoor glass jar, then my experience will be very useful.
Live food (such as red worms, water worms, etc.) ) is rich in nutrition and has the best palatability. But they usually only grow in dirty ponds, ditches and puddles. They are captured from these natural waters and carry a lot of bacteria and parasites. General cleaning is not easy to clean. Fish eat this food for a long time, and it is inevitable that they will get sick. Common diseases are white spot disease (melon disease), gill rot disease and third-generation worm disease, and these three diseases are the most difficult to cure. If found in time, it can be cured after treatment. But the pathogen enters the fish tank with each feeding, and it won't be long before the fish will get the same disease. So many times, not to mention the blow to fish farmers, goldfish itself can not stand, physical decline, thin body, ornamental value gradually lost ... will inevitably die young.
Finally, the goldfish were given a diet of "dry food+bread worms". Dry food, including dried red worms and artificial full-price feed, is not worse than live food, even more comprehensive, and the most important thing is cleaner, which greatly reduces the chance of goldfish getting sick. At the same time, feeding dry food should follow the principle of "eat less and eat more meals", and feed less times at a time. On the one hand, goldfish can digest better, and at the same time, it is easy to establish feelings with their owners. As soon as you get close to the fish tank, the fish will immediately gather around and ask for food. You should pay attention at this time, Kim. Fish are greedy, so the daily feeding amount must be controlled. You can't give it whenever you need it. Anyway, there is plenty of time! As long as the goldfish is healthy, you can enjoy feeding the goldfish every day, and your goldfish can also enjoy the unparalleled feeling brought by daily food. If you have a big goldfish, you can also try to feed some breadworms, even as a dessert. They are alive and absolutely clean. You may be afraid to eat your goldfish at first, but after you get addicted, you will definitely eat every meal.
Question 2: What food does goldfish eat? Goldfish is an omnivorous ornamental fish cultivated by human beings for a long time. They "love" to eat almost everything, and as long as they can see and reach things, they will happily taste them. Generally speaking, it is best to feed live food (such as red worms and water worms). ), goldfish grow fast, feeding dry worms or artificial feed is only a stopgap measure. However, the author has kept goldfish for nearly 20 years, but he has come to the opposite conclusion. Live food (such as red worms, water worms, etc.) It is nutritious and delicious, but it usually grows only in dirty ponds and ditches, carrying a lot of bacteria and parasites. General cleaning is not easy to clean. Goldfish eat this food for a long time, and it is inevitable that they will get sick. The author chose the recipe of "dry bread worm" for goldfish. Dry food includes dried red worms and artificial full-price feed, and its nutrition is not worse than that of live food, or even more comprehensive. The most important thing is cleanliness, which greatly reduces the chance of goldfish getting sick. At the same time, feeding dry food should follow the principle of "eat less and eat more meals", and feed less times at a time. If you have bigger goldfish, you can also try to feed some breadworms, even for dessert. It's alive and absolutely clean. Your goldfish may be afraid to eat at first, but after eating addiction, it is essential to ensure every meal. Goldfish is an omnivorous fish and likes to eat live bait such as Daphnia and earthworm. However, the source of live bait is limited, and some of them are not available at all, so dried fish worms are generally used instead, and synthetic bait with complete nutrients can also be fed.
Goldfish like to eat live red fish worms. If there are no live fish worms, you can buy dried fish worms to feed. If there are no fish worms, you can boil the millet and rinse it with cold water. Goldfish also like to eat it.
Because goldfish are greedy, they can only eat 80% to 90% when feeding. Live bait 10 ~ 15 minutes, dried fish and compound feed for 20 ~ 30 minutes. Feed 1 ~ 2 times a day when the water temperature is above 20℃, and only feed 1 time a day when it is below 19℃. Green, brown or black fish droppings indicate that goldfish eat moderately and digest and absorb well. When the fish's feces are white and yellow, it means that the fish is too full to eat.
I suggest buying some fish food, or if you can't buy bread?
Fish farming should always change water. My family always dies without changing water!
Question 3: What do goldfish eat with sufficient nutrition? Does it look nice? Red worms and water worms
Question 4: What fish is the most nutritious? There are many methods of "brain health care", among which eating more fish, especially marine fish, is the most beneficial to the brain. Fish is rich in unsaturated fatty acids (about 10 times higher than meat), which is an important substance for strengthening the brain. Marine fish contains docosahexaenoic acid and eicosapentaenoic acid, which are the most important substances to promote the development of nerve cells and have the function of strengthening the brain.
The epidemiological data of marine fish preventing coronary heart disease published the incidence of arteriosclerosis and coronary heart disease: the incidence rate of residents in Europe and America is the highest, and it is rare in Asian Japanese, while the Eskimos in the Arctic hardly suffer from this disease. Correspondingly, the most significant difference in the diet of residents in these three areas is that the average daily consumption of fish in Europe and America is 20g, that of Japan 100g and that of Eskimos is 400g.
Scientists concentrate on the composition analysis and research of fish, and find that fish oil, especially marine fish fat, contains a unique essential fatty acid-N-3 fatty acid. Studies have shown that N-3 fatty acids have an effect on human lipid metabolism. N-3 fatty acids can reduce triglyceride and total cholesterol in blood, slightly increase high density lipoprotein and reduce the synthesis of very low density lipoprotein in liver, so it can actively prevent arteriosclerosis and coronary heart disease. Scientists regard the discovery of N-3 fatty acids as one of the three major advances in coronary heart disease research in recent years.
N-3 fatty acid is the most abundant in fish, and its unit content is incomparable with other foods. If you eat more fish, you will get more N-3 fatty acids. Moreover, fish food contains more inorganic salts than common livestock meat, and is also rich in iodine and calcium, which is beneficial to the prevention and treatment of coronary heart disease.
Nutritional value of yellow croaker
Yellow croaker is rich in nutrition, high in protein, high in inorganic salts such as calcium, phosphorus, iron and iodine, and soft in fish tissue, which is suitable for digestion and absorption. The best thing is that its "garlic clove meat" has no broken thorns, and it is most suitable for the elderly, children and the infirm.
"Outline" records that yellow croaker "tastes sweet and nontoxic, and water shield is used as soup to stimulate appetite and replenish qi." Air-dried snapper is called white snapper. Roasted snapper can cure diarrhea and abdominal distension, which is not as good as fresh snapper. "
Men who eat more sea fish can nourish their brains.
"Men should pay more attention to protecting their brains and using them scientifically, because men's brains shrink much faster than women's." This is the research conclusion recently released by a group of scientists in the United States.
After adulthood, with the increase of age, the number of brain cells will obviously decrease gradually, but as far as the mortality rate of brain cells is concerned, men are twice as high as women.
It is best not to eat "mercury fish"
Generally speaking, the mercury content in marine fish is high, especially carnivorous marine fish. A study by Johns Hopkins University in the United States found that the mercury content of sharks, shark fins, tuna and groupers is high. According to the information released by the Food and Drug Administration, the seafood with the highest mercury content includes tuna, perch, cod, Gulf oyster, halibut, canned tuna, swordfish, shark and black cod. According to another investigation, trout, swordfish, tuna, mackerel, marlin, pike, whitebait, cod and swordfish also contain a lot of methylmercury. According to the regulations of American health department, the weekly mercury intake of human body should not be higher than 5 micrograms, that is, eating more than 6 pieces of tuna sashimi has exceeded the standard.
Tips for eating sea fish
1, don't eat more than two or three meals a month, and eat enough fish every time.
2. Choose to eat smaller fish.
3. Choose salmon, trout, catfish, shrimp, left-handed fish, Pacific salmon, yellow croaker and black crab fish.
4, eat less sharks, swordfish, shark's fin, tuna, grouper, cod, mackerel, etc.
5, eat less fish guts.
6. Eat less fish heads and skins.
7. Eat some broccoli, tomatoes, nuts, mushrooms, apples and whole grains.
8. People who are worried about the signs of heavy metal poisoning can consider doing a hair test.
Then, using yellow croaker as raw material, make several fish dishes to taste.
Generally speaking, the nutrition of fish is good, and I don't think it is necessary to pursue the most nutritious. The following are the nutritional status of some fish for reference only:
1, crucian carp
Crucian carp has the functions of invigorating qi and spleen, inducing diuresis to reduce swelling, clearing away heat and toxic materials, dredging collaterals and promoting lactation.
2. Carp
Has effects in invigorating spleen, stimulating appetite, promoting diuresis, relieving swelling, relieving cough and asthma, preventing miscarriage and promoting lactation, and clearing away heat and toxic materials.
3. Silver carp
It has the functions of warming middle warmer, benefiting qi, warming stomach and moistening skin, and is a health food for warming middle warmer and benefiting qi.
4. herring
Has the effects of invigorating qi, nourishing stomach, eliminating dampness, promoting diuresis, dispelling pathogenic wind and relieving vexation. The trace elements such as zinc and selenium contained in it help to fight cancer.

Question 5: What fish to eat is nutritious. Although you talk too widely, marine fish will do.
Question 6: What fish is more nutritious? Nutritional grade of fish
1. Marine fish
Marine fish (according to the percentage of DHA content in fish): tuna, tuna, mackerel, saury, sardine, eel, red trout, salmon, bamboo pod fish, fat-eyed herring, sea cucumber, hairtail, mullet, swordfish and golden-eyed snapper. Among them, the DHA content in tuna, tuna, mackerel, saury, sardine and other 100g fish is above 1g, which is a veritable "DHA fish", while the DHA content in tuna is as high as 2.877g, and the total fatty acid content is 20. 12g, which is actually. Nutritionists also point out that some fish are not rich in DHA, but rich in fish oil, especially salmon, red trout, cod, bonito, fat-eyed herring and cuttlefish.
2. Freshwater fish
Freshwater fish (according to the relative content of DHA in unsaturated fatty acids in fish): shad, red fish, white pond fish, snakehead, mandarin fish, black-eyed trout, bream, herring and silver carp.
Question 7: What do small fish like best? Moreover, buying a slightly better feed is also nutritious. Fish feed usually contains bran, barley and bean cake. Or small earthworms, red nematodes, very nutritious.
Question 8: What does the little goldfish eat besides fish food? Goldfish is an omnivorous fish and likes to eat live bait such as Daphnia and earthworm. However, the source of live bait is limited, and some of them are not available at all, so dried fish worms are generally used instead, and synthetic bait with complete nutrients can also be fed. Because goldfish are greedy, they can only eat 80% to 90% when feeding. Live bait 10 ~ 15 minutes, dried fish and compound feed for 20 ~ 30 minutes. Feed 1 ~ 2 times a day when the water temperature is above 20℃, and only feed 1 time a day when it is below 19℃. Green, brown or black fish droppings indicate that goldfish eat moderately and digest and absorb well. When the fish's feces are white and yellow, it means that the fish is too full to eat.
Question 9: What can goldfish eat to add color? Personally, I think red worms are good and nutritious.
The colored feed downstairs is also good.
