Curved or curled bodies in Salt and Pepper Corys often indicate a serious health issue, possibly due to poor water quality, nutritional deficiencies, or parasitic infections. Immediate attention is crucial as this condition can lead to secondary infections and even death. Owners should first assess their tank conditions and recent changes to the Cory's environment.

How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Perform a full water test
Check for ammonia, nitrite, nitrate, pH, and temperature levels.
Recommended: Water test kit - Observe feeding habits
Ensure the Cory is receiving a varied and balanced diet rich in vitamins and minerals.
- Inspect for external parasites
