What to check before treatment

  1. Test ammonia, nitrite, nitrate, pH and temperature.

  3. Check whether other fish are affected and whether new fish, plants or equipment were added.
  4. Avoid mixing medications based on one visible symptom alone.

Frequently asked questions

How should I use these fish symptom guides?

Start with water test results, the fish species and visible symptoms. Similar signs can have different causes, so these pages are educational starting points rather than a diagnosis.

When should I seek professional help?

Contact an aquatic veterinarian or fish-health professional for severe breathing difficulty, open ulcers, rapid deterioration, repeated deaths or symptoms that persist after water conditions are corrected.
