| Severe (extensive ulceration) | Professional fishery doctor diagnosis and treatment + isolation treatment | 14-30 days |
4. Suggestions on preventive measures
1.water quality management: Check key indicators such as pH value (6.5-7.5) and ammonia nitrogen (<0.02mg/L) every week, and use a water purifier or exposure to the sun to remove chlorine.
2.Stocking density: Follow the principle of "1 cm fish body length/1 liter of water" to avoid friction damage caused by crowding.
3.Nutritionally balanced: Alternately feed artificial feed and live bait such as frozen red worms to supplement vitamin C and E.
4.Environmental optimization: Remove sharp decorations, keep water temperature stable (temperature difference <2℃/day), and provide sufficient hiding space.
5. Special reminder from experts
The "Guidelines for Healthy Breeding of Ornamental Fishes" recently released by the Chinese Academy of Fishery Sciences specifically pointed out that the rising water temperature in spring is the season of high incidence of fish diseases, and it is recommended that the following prevention and control measures be taken:
• New fish must complete 14 days of quarantine and observation before entering the tank
• Preventive salt bath (concentration 0.5%, duration 15 minutes) once a month
• If sick fish are found, they should be isolated immediately to avoid cross-infection.
From the above analysis, it can be seen that fish scale loss is mostly caused by feeding and management problems. As long as it is handled promptly and correctly, most cases can be fully recovered. It is recommended that aquarists stay calm when encountering problems, take photos to record the development of symptoms, and then take targeted treatment measures.
