CATDOLL : CATDOLL: Why do fish not eat?

Why fish won't eat?

The temperature is too low: Fish usually don't eat because the temperature is too low. As a cold-blooded animal, it has a weaker ability to adapt to temperature, and low temperature will affect its appetite. Poor water quality: Poor water quality also has a great impact on fish, and it will also cause it to not eat. Food is not palatable: Fish also have a sense of taste, and if the food is not palatable, they will not eat. Fish are not hungry yet: If the last meal was too much and the feeding interval was short, the fish may not eat. 1. The temperature is too low. Fish usually don't eat because the temperature is too low. As a cold-blooded animal, it has a weaker ability to adapt to temperature, and low temperature will affect its appetite. If it is a tropical fish, the water temperature should generally be controlled above 20℃, and a heating rod should be installed in the fish tank to control the water temperature. If it is a wide-temperature fish, the water temperature should not be too low, preferably around 15℃.

2. Poor water quality Poor water quality has a great impact on fish and will also cause them to stop eating. If the water quality deteriorates seriously, it will not only make them lose their appetite, but also endanger their health. Usually, in order to maintain the water quality, filters need to be installed in the fish tank, and the water needs to be changed regularly to improve the water condition and ensure the health of the fish.

3. Food is not tasty. Fish also have a sense of taste. If the food is not tasty, they will not eat it. The food they choose varies according to the feeding habits of fish. If it is an herbivorous fish, you can feed it with aquatic plants or algae. Carnivorous fish should use animal feed such as small fish and shrimp. Omnivorous fish can eat a lot of things, and usually choose fish food.

4. Fish are not hungry If the fish ate too much in the last meal and the interval between feedings is short, the fish may not eat. In this case, do not continue to feed, because it will not eat even if you feed it, and it will cause microorganisms to multiply and the ammonia nitrogen content will increase, thus accelerating the deterioration of the water body, which is not good for the health of the fish.

Why do some goldfish not eat much fish food?

There are many reasons for not eating food;

The most basic thing is to ensure that the goldfish is healthy and disease-free. Sick goldfish will be lifeless, and in serious cases, there will be white spots, black spots, and flaky scales on their bodies.

Another thing is that you have just changed the breeding environment for the goldfish. The goldfish will not be used to it. This is normal. You just need to starve it for two days and then feed it. Don't feed it too much at the beginning.

The last one is probably a new feed. By the same token, if the fish is used to eating one kind of food and suddenly change it to another, for example, from artificial fish food to dried bloodworms, it will not be used to it.

Because they have not been artificially trained with bait, or the artificial training has not been successful, some fish must eat live bait and not feed.

Another possibility is that the fish is sick or cannot adapt to the new environment.

Some are herbivorous fish.

Fish are the oldest vertebrates. Some hybrids with different numbers of chromosomes are still fertile. They live in almost all aquatic environments on Earth, from freshwater lakes and rivers to saltwater seas and oceans. Fish are cold-blooded vertebrates that live in water all year round, breathe with gills, and use fins to assist body balance and movement.

According to statistics from a late Canadian scholar, there are 24,618 species of fish in the world, accounting for more than half of the named vertebrates, and new species of fish are constantly being discovered, with an average of about 150 species per year. In the past decade, more than 1,500 species have been added. Currently, there are about 32,100 named fish species in the world. It is the most primitive and lowest group in the subphylum of vertebrates.

Fish meat is rich in animal protein and phosphorus, nutritious, delicious, easy to digest and absorb by the human body, and plays an important role in the development of human physical and intellectual strength. Other parts of the fish can be made into cod liver oil, fish glue, fish meal, etc.

Some fish, such as goldfish and tropical fish, have various shapes and bright colors, and have high ornamental value. my country has a long coastline, numerous rivers and lakes, and a rich variety of fish. According to surveys, there are more than 1,000 species of freshwater fish in my country, and the famous "four major carps" (black carp, grass carp, silver carp, bighead carp) and carp, crucian carp, etc. are all major fine freshwater fish species in my country; there are about 2,000 known marine fish species in my country, and the common ones are hairtail, large yellow croaker, salmon, etc.

Goldfish cannot be kept in a washbasin as the space is too small and they are prone to lack of oxygen.

I will tell you the key points of raising goldfish at home: this is a summary of my experience in raising goldfish for more than 10 years, and it is not a long article downloaded from the Internet. It may be helpful for you to raise goldfish in the future.

1. Feeding: All feeds are nutritious animal feed and white sesame. Animal feeds include water fleas, earthworms, mealworms, caterpillars, and skinworms. The main feeds are earthworms and white sesame. Both red and black earthworms can be fed. Raw white sesame can be fed as the main food. White sesame is easy to buy. Goldfish love to eat it, it is easy to digest, and it is not easy to pollute the water quality. Do not feed the inferior goldfish feed you buy. Because this kind of feed has too much starch, poor nutrition, difficult to digest, and easy to pollute the water quality. Goldfish will be malnourished after eating it, and the growth of goldfish will be slower and they are prone to diseases. As long as goldfish eat easily digestible food, they will not die of bloating. When to feed? Generally, once in the morning and afternoon every day. It is not advisable to feed more, and feed until all the food is eaten. Otherwise, it will pollute the water quality.

2. Light: It is best to place the fish tank in a place where there is sunlight for 1-2 hours. In this way, the ultraviolet rays of the sun can be used to sterilize. It plays a role in disease prevention. This can reduce diseases. Try to prevent fish diseases as the main method and use medicine as the auxiliary method. At the same time, due to photosynthesis, the color of the fish body is also brighter and more beautiful.

3. Change water: Change water frequently to increase dissolved oxygen in the water. When changing water, only one-third to one-quarter of the water should be changed. Do not change a lot at once, or the fish will not adapt. It is very important to keep the water in the aquarium clear. Fish can only grow and grow fast if there is sufficient dissolved oxygen in the water. Otherwise, they will stop growing or even die. There is no definite answer to when to change water. It can be determined according to the water quality. Change water more often if the water is turbid, otherwise change less often.

4. Stocking density: Because the rectangular aquarium for domestic use is small in size, it is not advisable to raise too many fish. It is better to raise less rather than more. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6 to 8 small goldfish of 5 to 7 cm in length can be raised. For example, in a round glass tank with a diameter of 26 cm and a height of 13 cm, 4 to 6 small goldfish of 4 to 6 cm in length can be raised. Adult fish with a body length of more than 8 cm should not be raised in a small glass tank, but should be raised in a large glass tank or a ceramic tank, and equipped with a small oxygenator to prevent hypoxia. These stocking densities are only reference numbers, and they should be determined by the water temperature, the strength of the fish, and the quality of the water. They cannot be mechanical. Generally speaking, the larger the fish, the fewer the number of fish to be raised; raise more in winter and less in summer; raise more when the water temperature is low and raise less when the water temperature is high. If you master the above points when raising goldfish at home, you will be able to keep them healthy and lively, colorful, swimming in the water, and being loved by people, so that you will never get tired of watching them and have endless fun. You will definitely be able to raise them well. I wish you success
