- Check the water parameters for ammonia, nitrite, and nitrate levels.
Use a test kit to ensure they are within the optimal range for Clown Plecos.
Recommended: Water test kit - Observe the water temperature and ensure it's stable within the 22.0–26.0°C range.
Use a reliable thermometer to monitor the temperature.
Recommended: Thermometer - Inspect the fish for external signs of injury or parasites.

Change 25-30% of the tank water every 2-3 days.
- Stabilize the water temperature and maintain it within the optimal range.
Use a reliable heater and avoid rapid temperature changes.
- Administer appropriate medications if an infection is suspected, following the vet's instructions.
Antibiotics or antiparasitic treatments may be needed.
