How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Check the water parameters for ammonia, nitrite, and nitrate using a test kit.
This will help identify any water quality issues.
Recommended: Water test kit - Observe the tetra's behavior, appearance, and interactions with other fish.
Look for signs of illness or stress, such as clamped fins or reduced activity.
- Inspect the tank for any recent changes or disturbances.
Changes in water temperature, lighting, or the addition of new tankmates can cause stress.
- Review the tetra's diet and feeding routine.
Ensure the diet is balanced and not too rich in fat, which can lead to overeating and appetite loss.

This will create a calm environment conducive to eating.
