• Monitor water quality parameters daily to maintain pH between 6.5-7.5
• Change 1/3 of the water volume every week and use water quality stabilizer
• Install a high-efficiency filter to ensure ammonia nitrogen content <0.02mg/L
2. Physical damage treatment
• Remove sharp ornaments and use sleek stone instead
• Fish species with serious polyculture conflicts need to be isolated
• Apply fish-specific anti-inflammatory ointment to the injured area
3. Disease prevention and treatment measures
• Parasitic infections require trichlorfon medicated bath (concentration 0.3-0.5ppm)
• Nitrofuracillin (0.1g per 10 liters of water) is recommended for bacterial infections
• Keep the water temperature constant during treatment, raising it by 2-3°C will help recovery
4. Key points of fish scale regeneration and maintenance
| stage | time period | Maintenance focus |
|---|---|---|
| Early stage (1-3 days) | wound healing period | Keep water clean and avoid infection |
| Medium term (4-10 days) | Scale bed formation stage | Supplement protein and vitamins |
| Late period (11-20 days) | scale regeneration period | Appropriately increase light to promote calcium absorption |
