Protocol QT-05No antibiotic
External parasites
The sign is behaviour before it is a lesion: startling during feeding, and gathering into small groups swimming through each other.
Step 0 · Identify
What you see at the pond
Clear parasites before treating bacteria. With parasites present, antibiotics do not hold — the most repeated cause in the document.
- Startling during feeding
- Gathering into small groups swimming through each other
- Heavy mucus loss, sluggish, poor appetite
Handling
Day by day
Environment first, medicine after. The chart below includes the withdrawal period.

Withdrawal
None
No antibiotic, so no withdrawal period.
No improvement in 3–5 days
Parasites return if the bottom is still dirty. Repeat after 7–10 days and deal with the bottom properly, rather than raising chemical doses.
Note
Change 30% of the water once the fish are normal again, with PREMIX EDTA 1 kg/1,000 m³ after the change.
