CATDOLL : CATDOLL: I bought the silver arowana a few days ago, but it still won't eat. What should I do?

The following are several situations and countermeasures for dragon fish refusing to eat and eating a partial diet, for reference: 1. Problems between dragon fish and breeders, so that dragon fish go on hunger strike. This situation usually occurs when a new dragon fish enters the tank, or after surgery. Dragon fish are spiritual animals and are very sensitive to some new things and new environments. In addition, if you change the surrounding environment, they will also be afraid and refuse to eat. It should be noted that once the surrounding environment is determined, it should not be changed. In serious cases, changing the surrounding environment will cause the dragon fish to jump out of the tank and hit the tank. It is also a common problem that dragon fish will be afraid of the breeder and refuse to eat after surgery. Countermeasures: Adjust the water quality to a good state, add a night light on the upper part, turn off other lights, add an appropriate amount of vitamins, fast for 2-3 days, and then feed food. The purpose of this is to enhance the hunger of the dragon fish. After opening, spend more time with it to strengthen the familiarity between each other. Note that fish can be hungry, not full. Feeding too full can cause enteritis and ascites. 2. The refusal to eat is caused by poor water quality. The main reason is that the water is too old and the harmful substances in the water are too high, which leads to the loss of appetite for food. It is usually manifested in that when feeding, the fish bites twice and then spits it out without eating or lies down in the tank. Countermeasures: Fast for a few days. During the fasting period, the water quality should be adjusted and maintained well, the cultivation of digestive bacteria should be strengthened, and the water should be changed and the filter cotton and filter materials should be cleaned. A real case, a red dragon fish raised by a friend had this situation. After changing the water, digestive bacteria were added, and two AT3338 filters were added. After fasting for 4 days, the water quality improved, and the appetite of the dragon fish doubled. The size of 35 cm, from only 4-5 barley worms, now eats 25-30. 3. The reason for the arowana's hunger strike and partiality caused by the monotony of food is very simple, just like always asking you to eat fatty pork, one day you will get tired of it. The monotony of food can easily cause the arowana to have problems with incomplete absorption, being too fat or too thin. Countermeasures: Fast for 5-6 days, and improve the water quality to the best state at the same time. Vitamins can be added during this period. After the fish start to eat, pay attention to the combination of food and rhythmic diet (see the second for details). 4. Food refusal or poor appetite caused by too high or too low PH, mostly occurs when new fish come back or change the tank, due to the lack of understanding of the original water quality PH. Countermeasures: Understand the original PH value, gradually adjust the appropriate PH, and fast for 1-2 days. 5. Food refusal or poor appetite caused by a dragon fish catching a cold, mostly occurs when the weather changes and the temperature difference is large, and the symptoms occur, such as lying in the tank and not eating, or poor appetite. Countermeasures: Add appropriate amounts of penicillin and sea salt, pay attention to maintaining the temperature, and fast for two days. 6. Food refusal or poor appetite caused by internal parasites, the reason is that feeding insects, small fish, frogs and other foods, the internal parasites caused by them, the symptoms are very similar to enteritis, occasionally lying in the tank, irritable, at the beginning, the food intake will gradually decrease, and finally refuse to eat. Countermeasures: It is relatively easy to treat in the early stage of the above symptoms. Use waterlife, o to treat head holes. Mix about a quarter of a tablet with 20 ml of water and inject it into the body of the insects fed with a syringe. The dosage should not exceed 1/2-1/4 tablet. Too much dosage will cause certain harm to the fish body. Change 1/6 of the water, fast for 2 days, and add appropriate amount of vitamins. If the fish refuses to eat completely due to internal parasites and there is no other way, only a small operation can be performed. After the dragon is anesthetized, directly put a quarter of a tablet of waterlife, o to treat head holes, stuff it into the fish mouth to the stomach, put it in the tank to wake up, change 1/6 of the water, fast for 2 days, add appropriate amount of vitamins, and keep the water quality and temperature stable. 7. Refusing to eat or poor appetite caused by enteritis is caused by poor water quality and unclean food. There are symptoms of lying in the tank, irritability, and prolapse of the anus. Countermeasures: Improve water quality, fast for 2-3 days. If there is no improvement, add appropriate amount of penicillin or use intestinal medicine. After treatment, feed soft food such as shrimp meat with head and tail removed. 8. Fasting or poor appetite caused by environmental inadaptability is mostly caused by the new fish entering the tank to adapt to the new environment and the new breeder. During this period, the dragon fish is more easily frightened. This involves many issues, such as PH, water quality too soft or too hard, fish tank settings, lighting, water temperature, water flow, water dilution, etc. Countermeasures: First of all, before the new fish enters the tank, the water quality should be adjusted to the optimal state, the water and temperature should be carefully adjusted, and the fish should be fasted for two days. The breeder should spend more time with the fish to reduce the fear of the arowana. In this way, most of the new arowanas will refuse to eat when entering the tank; adjust the water level and the width of the water area according to the size of the arowana to reduce the degree of shock. The water level and the width of the water area should not be too high for small arowanas, but it is not absolute. It varies from arowana to arowana. Because arowanas are very individual animals, a fish tank with a background gives arowanas a certain sense of security. Adding a certain amount of mixed fish can only help arowanas adapt to the new environment as soon as possible and strengthen their competitiveness for food. 9. Spontaneous refusal to eat usually occurs during the breeding process. This problem involves many aspects. Usually, they will stop eating the next day after being fed today. Countermeasures: First, test the water quality of PH, NO2, NO3, GH, KH to see if the water quality is at normal values, and then see if the food is too single, whether internal parasites, enteritis and the above problems are eliminated one by one, and choose an appropriate countermeasure. 2. How to fast rhythmically In terms of fasting rhythmically, you must be people-oriented. You cannot let your dragon have the final say and let it eat whatever it likes. Otherwise, it will be troublesome to pick things up in the future. You must establish the principle that when you raise a dragon, you cannot let the dragon lead you by the nose. Everyone has a different rhythm for feeding a dragon. You need to adjust the rhythm according to the dragon. You should usually observe your dragon more, find out what it likes to eat and what its temper is like, and then formulate fasting measures accordingly. Simply put, it is training. The benefit of fasting rhythmically is that it makes the dragon feel hungry all the time, it is not picky about food, and it is nutritious, which is of great help to its hair color and body shape. At the same time, it can stimulate the stomach by updating the water quality and adding nutrients and vitamins. The mouth is used to assist in completing the fasting measures. The rhythm mentioned here refers to the feeding time cycle and the combination of food. With a good food menu and the adjustment of feeding frequency and feeding amount, such as specifying 1-2 fasting days in 7 days a week, which are relatively separated, on fasting days, you can stimulate the desire of dragon fish for food by updating water quality and adding nutrients and vitamins. At the same time, the adjustment of feeding amount is generally from 2 meals a day to 1 meal. For 2 meals a day, you can eat 40% to 50% full per meal (determined by individual circumstances), and for 1 meal a day, you can eat 90% to 110% full per meal (determined by individual circumstances). Let me reiterate that good water quality is the prerequisite for rhythmic fasting.

1. Environmental changes cause the silver arowana to stop eating

Environmental changes include two aspects:

(1) Not adapting to the new environment after entering the tank

(2) Changes such as the relocation of the fish tank, the replacement of the background, the increase or decrease of the number of fish in the tank, and the layout around the fish tank.

Countermeasures: For this kind of situation, there is no need to worry, just maintain good water quality and wait for the silver arowana to slowly adapt to the changes in the new environment. You can only wait patiently.

2. The water is too old and the silver arowana does not eat

The frequency of water changes and filter cleaning will cause the water quality to be too old, affecting the health of silver arowana

Countermeasures: Change the water regularly every week. For 3-5 days after the silver arowana stops eating due to old water quality, change the water by 1/6 to 1/8 every day to stimulate the appetite of the silver arowana.

3. Single feeding causes silver arowana to not eat

Feeding the same food for a long time will cause the silver arowana to get bored and no longer be interested in this type of food.

Countermeasures: Change the food, use other foods to lure the silver arowana, and the diversification of feeding will play an important role in the growth of the silver arowana.

4. Seasonal changes cause silver arowana to stop eating

Silver Arowana can keenly perceive the changes of spring, summer, autumn and winter.

Countermeasures: Normal phenomenon, maintain water quality and wait patiently

5. Overfeeding causes the silver arowana to not eat

Some fish lovers cannot control the amount of food for silver arowana, and feed them too much food at one time, which may cause indigestion in silver arowana.

Countermeasure: Feed until the fish is 70% full, with a slightly bulging belly. If the fish is fed too much and stops eating, stop feeding and wait for the fish to recover slowly.

6. Changing the water after feeding causes the silver arowana to stop eating

Changing the water after feeding the silver arowana will cause discomfort to the fish, and in severe cases, the fish will vomit.

Countermeasure: Remember to stop feeding before changing water

7. Disease causes silver arowana to stop eating

When the silver arowana is sick, the occurrence of diseases such as internal parasites, body surface congestion, and head hole disease is a torture for the silver arowana, and naturally it will not have the desire to eat.

Countermeasures: Stop feeding, maintain water quality, treat the disease with appropriate medicine, and the silver arowana will eat again after recovery.
