2. Analysis of the causes of death of small goldfish
According to case statistics from pet hospitals and forums, the following are the main patterns of abnormal death of small goldfish:
| fatal factors | Proportion | Typical symptoms |
|---|---|---|
| Water quality deteriorates | 43% | Increased mucus in fish and congestion in gills |
| overfeeding | twenty two% | Abdominal swelling and abnormal excretion |
| thermostress | 18% | Imbalance in swimming and darkening of body color |
| pathogenic infection | 12% | White spots on the body surface and ulcerated fins |
3. Scientific maintenance solutions
1.water quality management: Check the ammonia nitrogen/nitrite concentration every week, and change the water volume no more than 1/3. It is recommended to use:
| Tool name | Function | Frequency of use |
|---|---|---|
| Electronic water quality testing pen | Monitor pH value in real time | 1 time a day |
| Nitrifying bacteria capsules | Establish ecological balance | Once every two weeks |
2.Feeding regulations: Adopt the "3-minute rule" - the feeding amount should be eaten within 3 minutes, specific reference:
| Goldfish body length (cm) | Daily feeding amount (grams) | Recommended number of meals |
|---|---|---|
| 3-5 | 0.1-0.3 | 2 times |
| 5-8 | 0.3-0.5 | 3 times |
3.disease prevention:Isolate immediately when abnormality is discovered. Common treatment options:
| disease type | therapeutic drugs | Course of treatment |
|---|---|---|
| white spot disease | methylene blue solution | 5-7 days |
| tail rot disease | yellow powder medicated bath | 3 days |
4. Special reminder from experts
Recently, the phenomenon of "returning to the south" has occurred in many places across the country. A sudden increase in air humidity has led to a decrease in dissolved oxygen in fish tanks. Data from the Chinese Academy of Fisheries Sciences shows that the mortality rate of ornamental fish in such weather increased by 37% year-on-year. It is recommended that:
• Install oxygen pump to extend to 8 hours per day
• Cover the fish tank to prevent condensation
• Suspend the use of ultraviolet germicidal lamps (will accelerate oxygen consumption)
Through systematic management, the mortality rate of small goldfish can be significantly reduced. If death cases occur continuously, it is recommended to record a video of the fish swimming and consult a professional fish disease doctor.
