What should I do if the silver arowana doesn’t eat?
As a popular species among ornamental fish, silver arowana is loved by aquarists for its elegant body and unique colors. However, many fish farming enthusiasts have recently reported that silver arowana refuses to eat, sparking widespread discussion. This article will combine the hot topics and scientific fish farming knowledge on the Internet in the past 10 days to provide you with a detailed analysis of the reasons and solutions for the silver arowana not eating.
1. Top 5 recent popular fish farming issues (data source: Aquarium Forum statistics)
| Ranking | Question type | Discussion popularity | Main occurrence period |
|---|---|---|---|
| 1 | Silver Arowana refuses to eat | 87% | Season change period |
| 2 | Abnormal water quality | 76% | Continuous rainy days |
| 3 | white spot disease outbreak | 65% | When water temperature fluctuates greatly |
| 4 | polyculture conflict | 53% | After new fish enter the tank |
| 5 | Equipment failure | 42% | Not inspected for a long time |
2. Analysis of the six major reasons why Silver Arowana does not eat
According to recent statistics of 200+ cases, the refusal of silver arowana to eat is mainly related to the following factors:
| Reason type | Proportion | Typical symptoms |
|---|---|---|
| Water quality deteriorates | 35% | Ammonia nitrogen exceeds the standard and the fish body becomes dark |
| environmental stress | 28% | Refusing to eat after entering a new tank/changing tanks |
| disease infection | 18% | With white stools or congestion |
| Single feed | 12% | Feeding only one kind of bait for a long time |
| Temperature discomfort | 5% | Water temperature is lower than 26℃ |
| Breeding behavior | 2% | Loss of appetite during estrus |
3. Targeted solutions
1.water quality management: It is recommended to change 1/3 of the water every week, keep the pH value at 6.5-7.5, and the ammonia nitrogen content <0.02mg/L. The recently hotly discussed "Probiotic Water Adjustment Method" can significantly improve the digestive system.
2.Environmental optimization: Add sunken wood or aquatic plants to provide shelter space, and control the light intensity at 1000-1500lux. The "progressive light adjustment method" shared by an aquarist can help a silver dragon that refuses to eat to resume eating within 3 days.
3.Disease prevention and treatment: If it is found that you can use metronidazole (0.2g per 100L of water) for internal shipments, and methylene blue medicated bath is recommended for outbound shipments. The latest research shows that allicin-mixed bait has a significant effect on intestinal conditioning.
4.Feed improvement: The following bait combinations are recommended:
| time | Bait type | Nutritional supplements |
|---|---|---|
| Monday/Wednesday/Friday | Live bait (small fish/shrimp) | B vitamins |
| Tuesday/Thursday | Special pellet feed | Spirulina powder |
| weekend | Insects (crickets/mealworms) | Calcium supplement |
4. Advanced conditioning techniques
1.temperature stimulation method: Slowly increase the water temperature to 30℃ for 3 days. 90% of cases show that it can activate appetite. However, it is important to note that the daily temperature rise does not exceed 2°C.
2.peer induction: Keeping several actively eating arowanas together can produce a "herd effect". Recent experimental data shows that this method is effective as high as 78%.
3.starvation therapy: Healthy adult fish can tolerate fasting for 7-10 days, but young fish should not exceed 3 days. It is recommended to use it in conjunction with water quality monitoring.
5. Things to note
• Avoid changing feed brands frequently
• Disable activated carbon filtration during treatment
• Severe food refusal (more than 2 weeks) requires professional fish doctor consultation.
• The actual effect of the recently popular "sonic food attractant" is questionable, so it is recommended to try it with caution
Through system analysis, it can be seen that the silver arowana's refusal to feed is mostly a signal of environmental incompatibility. As long as the cause is identified and treated symptomatically, and combined with recent effective conditioning methods verified by aquarists, eating can usually be resumed in 5-7 days. It is recommended to establish a feeding log to record water quality parameters and feeding conditions, which is very helpful in preventing food refusal.
