Dinosaur fish do not eat. This is because they have poor digestion, or it may be because their water quality is not clean. Owners need to pay more attention and make adjustments in time.
1. Poor water quality:
Antifeeding caused by poor water quality occurs in all sizes. It is generally caused by the water body being too old. Some dragon friends collect feces every day. A very small amount of new water is added. After a period of time, the water body will easily become old and cause the arowana to refuse to eat. However, measuring various parameters in the water at this time is basically normal. At this time, it is recommended that breeders who operate in this way should still do a quantitative water change regularly (2 weeks or 3 weeks), such as changing 1/4 to 1/5 of the entire tank of water. This is effective in maintaining water quality. , and at the same time, the appetite of the arowana is also guaranteed. Countermeasures: After the food refusal occurs, change about 1/6 to 1/8 of the water in the tank every day. It is best to continue this method for 3 to 5 days. It should be noted that new water must be treated.
2. Indigestion:
This situation may occur at all stages of the growth of arowana. Often the breeder finds better food or does not control the food intake well. After the newcomers feed the fish, if they are fed too much at one time, the fish will not digest properly, resulting in a period of refusal to eat, often accompanied by the movement of climbing into the tank. There are also aquarists who change a large amount of water after a large amount of feeding, causing the fish to become unwell and even causing the arowana to vomit food. At this time, the fish will also refuse to eat for a period of time. Therefore, it is recommended that feeders should feed 7 to 8 minutes of fullness at a time, so that the arowana can always maintain a strong appetite. And be sure to stop eating on the day of a large water change to avoid discomfort. Countermeasures: For overfed arowana, you can use new water stimulation and heating control to stimulate digestion. If the arowana suddenly refuses to eat because of a large amount of feeding by the breeder, please do not use insects and other foods to induce food, but You should take the initiative to stop eating and use the above methods to stimulate digestion. Feeding can only be resumed after the arowana has finished digesting its food and has appetite.
3. Arowana disease:
Most diseases of the internal organs of the fish may lead to food refusal, such as internal parasites, internal inflammation, etc., which are generally accompanied by various diseases. Characteristics: Symptoms include sunken eyes, congestion on the body surface, abdominal distension, anal swelling and redness, holes in the head, body bending and other symptoms. At this time, we can calmly analyze and prescribe appropriate medicine to cure the disease. At the same time, the arowana will naturally start to eat. About the strategy: Prescribe the right medicine to treat the symptoms and treat both the symptoms and the root causes.
4. Conscious phased fasting:
This situation generally occurs at the sub-adult or adult stage of 40 to 50 centimeters. In the process of raising arowana from small to large, because it is full of food all day long, it may suddenly start to stop eating at a certain stage. This stopping of eating may be a natural reaction of the species. If the fish is in good condition and is completely normal, please Don't pay attention, just wait patiently. Measures: Maintain water quality and wait patiently.
5. Simple food anorexia:
Although most arowanas like insect food, if they are fed crickets all day long, there may be a day when they are no longer interested in crickets. , feed at this timeRiver fish may make the arowana feast, so general feeding is useful for maintaining the appetite of the arowana. About policy: changing food.
6. Environmental changes:
Environmental changes include moving the tank, changing the background, changing the arrangement in the tank, etc. It is possible that this kind of emergency will cause the arowana to suffer forever. The early refusal to eat will be accompanied by behaviors such as climbing in the tank, swimming quickly, being easily frightened, grinding the tank left and right, and turning on the corner of the machine. The sound of the filter outlet has been improved for some time to stabilize the flow of water into the tank. However, the arowanas in the polyculture tanks that have become accustomed to the sound of water flow are in a nervous state, easily frightened, and generally refuse to eat. They return to the sound of water flow. After a few dawns the situation disappeared. Countermeasures: Find the reason, reply if you can, and wait patiently for the corresponding process if you can't.
7. The shrinkage of polycultured fish causes the arowana to feel isolated:
A dragon tank may generally contain Thai tigers, freshwater stingrays, flying phoenixes, parrots, etc. Fish farming may simply be polyculture of arowanas. If the arowanas have become accustomed to this situation and suddenly take away their polyculture companions, or suddenly change from polyculture to monoculture, most of the arowanas will be Refusal to eat, it can be imagined that having mixed fish is mentally beneficial to the arowana. Once its accustomed companionship disappears, the sense of isolation will make it not want to eat. About the policy: Reply to the mixed culture situation.
8. Estrus time:
During the growth period, especially when the female fish is pregnant with eggs, the rapid development of the abdominal ovaries makes the abdomen extremely full, forcing the intestines and swim bladder, As a result, the arowana will refuse to eat for a long time, which can last for several months. At the same time, the body does not float very flexibly, which can be seen through the shaking of the tail. It is inevitable to stop eating at this time, so don’t pay attention to it. Be patient and prepare to grow. That’s it.
9. Seasonal stop eating:
Due to seasonal changes, especially in the Shuofang area, arowanas at this age are prone to stop eating. Although the tank is in a constant temperature environment, sensitive arowanas You can still feel the change of seasons. The refusal to eat at this time may have no obvious reason, and it will naturally return a few days later. There are many other reasons for Arowana to stop eating. Breeders need to analyze and observe patiently when encountering a situation of stopping eating, understand the situation of Arowana, and face it easily.
Pay attention to the specific situation of dinosaur fish and make targeted improvements.
