How to Diagnose the Cause

Follow these steps in order. Stop when you identify a likely cause and move to treatment.

  1. Observe the fish for other signs of stress or illness.

    Look for changes in color, appetite, or behavior.

  2. Check the water parameters using a reliable test kit.

    Ensure ammonia, nitrite, and nitrate levels are within the optimal range.

    Recommended: Water test kit
  3. Inspect the tank for any aggressive tankmates or hiding spots that may cause stress.

    Ensure the tank is set up to prevent aggression.

  4. Evaluate the diet and consider if it meets the nutritional needs of the Valentini Puffer.

    Ensure the tank is large enough for the fish to swim freely.

  3. Adjust the diet to include high-quality, varied food options and vitamin supplements.

    Feed a balanced diet rich in meaty foods and omega-3 fatty acids.

  4. Treat for external parasites with a suitable medication if present.
