2. Step-by-step guide to treatment plan
1.Isolation and observation: Immediately transfer the sick fish to a separate treatment tank to avoid secondary damage.
2.Water quality testing: Use professional testing tools to check the following indicators:
| Test items | normal range | emergency handling standards |
|---|---|---|
| pH value | 6.5-7.5 | <6.0 or >8.0 needs to be adjusted |
| Ammonia nitrogen content | 0mg/L | >0.5mg/L Change water immediately |
| nitrite | <0.3mg/L | >1mg/L dangerous value |
3.drug treatment: Choose the corresponding plan according to the cause:
| Cause | Recommended medicine | How to use |
|---|---|---|
| bacterial infection | Yellow powder (nitrofurazone) | Add 0.1g per 10 liters of water |

| Parasite | Trichlorfon | Use half as directed |
3. Preventive measures hotly discussed across the internet
1.Routine maintenance: Change 1/3 of the water every week and keep the water temperature constant (tropical fish 26-28°C).
2.Nutritional supplements: Recent ranking of popular fish food additives:
| Additive type | Frequency of use | Efficacy |

3.Environmental optimization: Arrange shelters according to the characteristics of fish species to reduce the possibility of fights.
4. Things to note during the recovery period
1. Stop eating for 2-3 days during treatment to reduce the metabolic burden on the fish.
2. Use an air pump to increase dissolved oxygen and promote metabolism.
3. Closely observe the growth of new scales. The normal regeneration cycle is 15-30 days.
5. Special reminder from experts
There is a misunderstanding in the "salt bath omnipotence theory" that has been circulated on the Internet recently: salt concentration exceeding 3% will destroy the mucus layer of fish and delay recovery. It is recommended to use professional fish salt and control the concentration at 0.5%-1%.
With the above structured solutions, combined with patient care, your fish will be back to good health in no time. Remember prevention is better than cure and regular maintenance is the way to go with your fish.
