|---|---|---|
| Warming therapy | Gradually increase the water temperature to 28-30℃ and maintain it for 3-7 days | The heating rate should not be too fast, no more than 2℃ per day |
| salt treatment | Add 3-5 grams of salt per 10 liters of water | Use non-iodized salt, use with caution for sensitive fish species |
| drug treatment | Use special drugs such as Baidianjing | Use strictly according to the dosage instructions |
| Water change treatment | Change 1/3 of the water every day to keep the water clean | The new water temperature should be consistent with the original tank water |
3. Precautions during treatment
1.Isolate sick fish:If white spot disease is discovered, the sick fish should be isolated immediately to prevent infection of other healthy fish.
2.Enhance filtering:Keep the filtration system running efficiently during treatment, but be aware that medications may affect nitrifying bacteria.
3.Stop feeding:When the condition is serious, feeding can be suspended for 1-2 days to reduce the burden on the fish.

5. Common misunderstandings
In recent discussions, aquarists have pointed out several common treatment misunderstandings:
1.Blind medication:Over-reliance on drugs and neglect of basic treatments, such as warming, water changes, etc.
2.Incomplete treatment:Stopping treatment as soon as symptoms disappear can lead to relapse.
3.Ignore the environment:Only focus on drug treatment without improving the breeding environment.
4.Mixing medications:Using multiple drugs at the same time may cause adverse reactions.
6. Recovery care
After treatment, goldfish require special care:
1.Gradually cool down:Lower the temperature by 1°C every day until the original water temperature returns.
2.Supplementary nutrition:Provide vitamin-rich feed to help restore physical fitness.
3.Keep watching:Monitor closely for 1-2 weeks to ensure complete recovery.
4.Disinfect fish tank:Clean the fish tank thoroughly to kill any remaining parasites.
