How to Diagnose

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

  1. Observe the fish's swimming patterns and behavior closely.

    Note if the fish is swimming erratically or lying on the bottom, which may indicate a more serious condition.

  2. Inspect the fish for signs of injury or parasites.

    Look for lumps, spots, or any visible parasites.

  3. Check the fish's diet and feeding habits.

    Ensure that the fish is not being overfed, and that the diet is appropriate for Dwarf Puffers.

    Measure ammonia, nitrite, and nitrate levels, as well as pH and temperature.
