CATDOLL : CATDOLL: Why does the dragon fish not like to eat?

Why does the dragon fish not eat?

1. Being frightened.

1. Reason: Arowana may not eat because it is frightened. Although Arowana looks domineering, they are easily frightened. If someone speaks loudly or hits the fish tank, they will be frightened.

2. Solution: The breeder needs to ensure that the surrounding environment is quiet and reduce the number of times they appear around the fish tank, so that the dragon fish can recover quickly. After recovery, the breeder can first try to feed them with their favorite food.

2. Environmental changes.

1. Reason: Arowana suddenly stops eating, it may be that the environment changes too much, causing them to feel uncomfortable. The more common reasons are excessive water changes, sudden temperature changes, and a lot of cleaning of filtration equipment.

2. Solution: The breeder first needs to stabilize the pH value of the water between 6.5-7.5, then keep the water temperature between 24-28℃, and finally strengthen filtration and oxygen to help the arowana recover quickly.

1. Poor water quality or too old water. Feeding refusal caused by poor water quality occurs in all sizes. It is generally caused by too old water. Some dragon friends extract feces every day and add a very small amount of new water. After a period of time, the water body will easily become old, causing the fish to refuse to eat. The various parameters in the water are basically normal. I personally recommend that fish friends who do this should still do a quantitative water change regularly (2 or 3 weeks), such as 1/4 to 1/5, which is good for the maintenance of the water body and the appetite of the dragon fish. Countermeasures: After refusing to eat, keep changing the water by about 1/6 to 1/8 for 3-5 days. The new water must be treated. 2. Indigestion after a large amount of feeding or changing water after a large amount of feeding. This situation may occur at any stage. Often, dragon fish friends find better food or feed strangers who have poor control of their food intake. They feed too much at one time, and the fish are indigestible, causing a period of refusal to eat, often accompanied by the action of climbing the tank. Some fish lovers also change a lot of water after feeding a lot, which causes discomfort to the fish, and even vomiting in the stomach, and the fish will refuse to eat for a period of time. Therefore, it is recommended that fish lovers feed 70% to 80% full at a time, so that the dragon fish can always maintain a strong appetite. And stop feeding on the day of a large water change to avoid discomfort. Countermeasures: For over-full dragon fish, new water stimulation and temperature increase can be used to stimulate digestion. If the owner really refuses to eat suddenly after a large amount of feeding, please do not use insects and other foods to lure food, but take the initiative to stop feeding and use the above methods to stimulate digestion. Wait until the dragon fish digests the food and has an appetite before resuming feeding. 3. Fish disease Most diseases of the internal organs of fish may cause refusal to eat, such as internal parasites, inflammation of internal organs, etc., which are generally accompanied by various disease characteristics: sunken eyes, congestion of the body surface, abdominal distension, swelling and redness of the anus, head holes, body bending and other symptoms. At this time, calm analysis, symptomatic treatment, and cure the disease while the dragon fish naturally opens its mouth to eat. Countermeasures: symptomatic treatment, both symptomatic and root treatment. 4. Spontaneous phased food cessation This usually occurs in the middle stage of 40 to 50 cm. When the dragon fish is raised from small to large, it may suddenly stop eating at a certain stage because it is full all day long. This situation is described in the "Dragon Fish Special Issue". This food cessation may be an instinctive reaction of the species. If the fish is in good condition and everything is normal, please ignore it and wait patiently. Countermeasures: maintain water quality and wait patiently. 5. Single food anorexia Although most dragon fish like insect food, if they are fed with crickets all day, maybe one day they are no longer interested in crickets. At this time, they may feast on river fish. Therefore, comprehensive feeding is good for dragon fish to maintain their appetite. Countermeasures: change food. 6. Urgency of environmental change Environmental changes include moving the tank, changing the background, changing the layout of the tank, etc. This urgency causes the dragon fish to refuse to eat for a long time, and it will also be accompanied by climbing the tank, swimming quickly, being easily startled, grinding the tank up and down, and being sluggish in one corner. I once improved the sound of the filter outlet for a while, so that the water flow into the tank smoothly, but the dragon fish in the mixed tank that had become accustomed to the sound of the water flow showed a state of tension, were easily startled, and collectively refused to eat. After the sound of the water flow was restored, the situation disappeared after a few days. Countermeasures: Find the cause, recover if you can, and wait patiently for the adaptation process for those that cannot be recovered. 7. Loneliness caused by the reduction of mixed fish Dragon tanks generally may have mixed fish such as tigers, rainbows, flying phoenixes, and parrots, or directly mixed dragon tanks. In this case, if the dragon fish has become accustomed to it, and suddenly its mixed companions are taken away, or suddenly changed from mixed breeding to single breeding, most of the dragon fish will refuse to eat. You can think about it. Mixed fish are beneficial to the spirit of the dragon fish. Once his accustomed companions disappear, loneliness will make him lose his appetite. Countermeasures: Restore the mixed breeding environment. 8. During pregnancy and reproduction, especially when the female fish is carrying eggs, the abdomen is extremely swollen due to the rapid development of the ovaries in the abdomen, which compresses the stomach, intestines and swim bladder, causing the dragon fish to refuse to eat for a long time, up to several months. At the same time, the body is not very flexible in floating up and down, which can be seen from the swinging of the tail. It is inevitable to stop eating during this period. Don't pay attention to it, just prepare for breeding patiently. 9. Seasonal fasting Due to seasonal changes, especially in the northern region, dragon fish are prone to stop eating in spring and autumn. Although the tank is a constant temperature environment, sensitive dragon fish can still feel the change of seasons. The refusal to eat at this time may be due to unknown reasons, and it will recover naturally after a few days.

There are many reasons why arowanas don't like to eat, such as water quality deterioration, being frightened, changing environment, food not being fresh and tasty, etc. These can cause arowanas to refuse to eat or not like to eat. Let's analyze them in detail:

1. Not adapting to the new environment

This symptom often occurs in newly brought back arowana. The newly brought back arowana refuses to eat because they are not adapted to the new environment.

Solution: For this kind of refusal to eat, generally ensure that the water quality is good, and the fish will start eating after a while, so there will be no problem. In addition, the newly brought back little dragon fish is timid and easily anxious, so don't use too bright lights, and try not to make loud noises near the fish tank to prevent the dragon fish from being frightened and prolonging the refusal to eat.

2. Human-induced changes in the environment

This symptom often occurs in arowana that has been kept for a period of time. Because the owner changes the environment in the fish tank, the arowana is not used to it or is in a bad mood, and thus refuses to eat.

Solution: You can let the arowana adapt slowly. If the owner cannot bear it, you can restore the fish tank to its original environment.

3. Fright

Fright is also a factor that causes arowana to refuse to eat.

Solution:

A: Shock inside the fish tank: Shock inside the fish tank mainly occurs in mixed aquariums, mainly caused by other fish fighting or snatching food. For this situation, the isolation and resting method is generally adopted.

B: Human-caused shock: Human-caused shock mainly includes: tapping the tank, adjusting the tank environment, changing the tank background, etc. For refusal to eat caused by this situation, it is generally recommended to turn off the lights and rest the fish. During the resting process, try not to get close to the fish tank or make loud noises near the tank.

4. Changes in pH

Arowana are very sensitive to changes in pH, and drastic changes in pH will cause the arowana to refuse to eat.

Solution: For food refusal caused by pH changes, generally speaking, you should first ensure the stability of the pH, and then wait for the arowana to adapt.

5. Seasonal food refusal

For seasonal food refusal, the only option is to maintain the water quality and wait for the arowana to eat.

6. Poor water quality or too old water

Feeding refusal caused by poor water quality occurs in all sizes. It is usually caused by the water being too old. Some dragon friends extract feces every day and add a very small amount of new water. After a period of time, the water will easily become old, causing the fish to refuse to eat. When measuring various parameters in the water, they are basically normal. I personally recommend that fish friends who do this should still change the water every day or every other day, such as 1/6 to 1/8, which is good for maintaining the water quality and maintaining the appetite of the dragon fish.

Countermeasure: After the fish stops eating, keep changing the water by about 1/6 to 1/8 every 3-5 days. The new water must be treated.

7. Indigestion after feeding a large amount or changing water after feeding a large amount

This situation can happen at any stage. Often, after a dragon fisher finds better food or feeds a stranger who cannot control the amount of food, the dragon fish will be fed too much at one time, which will cause indigestion and cause the fish to refuse to eat for a period of time, often accompanied by the action of climbing the tank. Some fish fishermen also change a lot of water after feeding a lot, which will cause the fish to feel uncomfortable and even vomit in the stomach. The fish will also refuse to eat for a period of time. Therefore, it is recommended that fish fishermen feed the dragon fish 70% to 80% full at one time, so that the dragon fish can always maintain a strong appetite. And on the day of a large water change, the fish must stop feeding to avoid discomfort.

Countermeasures: For overfed arowana, you can use new water stimulation and temperature increase to stimulate digestion. If the owner really refuses to eat suddenly after feeding a large amount, please do not use insects and other foods to lure the fish to eat. Instead, stop feeding actively and use the above methods to stimulate digestion. Feeding can only be resumed after the arowana has completed digestion of the food and has an appetite.

8. Fish diseases

Most diseases of the internal organs of fish may lead to food refusal, such as internal parasites, inflammation of internal organs, etc., which are generally accompanied by various disease characteristics: sunken eyes, congestion of the body surface, abdominal distension, swollen and red anus, holes in the head, bent body, etc. At this time, calmly analyze and prescribe the right medicine. While curing the disease, the arowana will naturally open its mouth to eat.

Countermeasures: Prescribe the right medicine for the right disease and treat both the symptoms and the root cause.

First of all, is the fish tank the wrong size?

Or maybe the food you give it doesn't suit its appetite?

Feeding of Arowana: When eating, Arowana will hit a certain angle in the tank and get injured. It is best to feed it in the middle of the tank. Arowana is a carnivorous animal. Most Arowanas eat frogs, loaches, crickets, goldfish, grasshoppers, shrimps, etc. There is a coloring issue when feeding. For example, feeding red Arowana with red arrows or shrimps can enhance the color of the red Arowana to a certain extent, because red arrows and shrimps contain red pigment. When young fish under 12 cm are just beginning to eat raw bait, you can feed them with white mealworms that have just shed their shells, shrimps (be sure to remove the head and tail, and it is best to peel them into shrimp balls to avoid the hard shell hurting their stomachs), bloodworms and other more palatable baits. Eat small meals and feed four times a day. Arowanas about 15 cm can be fed with normal mealworms and shrimps (it is best to remove the shrimp swords), and can also be fed with 1.5 cm small fish. At this time, Arowanas grow rapidly and have an amazing appetite. The number of times and amount of feeding can be appropriately increased. Arowanas over 20 cm can be fed with larger fish, shrimp, loach, meat and other baits. You can also feed various insects and other live baits, which are the favorite foods of Arowanas, but be careful not to let these baits be contaminated. In addition, viscera, especially liver, are not suitable for feeding Arowanas, as their high fat content can cause diseases in Arowanas. Goldfish is not a good bait among live baits. Studies have shown that the infectious diseases or parasites contracted by Arowanas that feed exclusively on goldfish and are kept in small aquariums are almost all transmitted by goldfish. It is best to use beef with less fat content as artificial bait. Of course, if you have the conditions, you can buy finished Arowana bait. However, when Arowanas are first fed with artificial feed, they will be very uncomfortable and need to be trained with artificial feed.

Do you feed it live bait? This carnivorous fish generally doesn't like to eat dead food. If it doesn't eat for a long time, it may be sick.
