Frequently Asked Questions

A symptom timeline helps you track disease progression, treatment response, and recovery. It is invaluable when consulting a vet or dealer because it provides an objective record of what happened and when.

Record any behavioral changes (flashing, lethargy, appetite loss), physical signs (spots, ulcers, discoloration, swelling), and environmental changes (water parameters, temperature shifts, new fish additions).

Use the copy/export function to create a shareable text summary. You can email or print this for your vet or dealer. Include photos whenever possible for better diagnosis.

Go back as far as you can remember. Often the earliest subtle signs (slight behavioral change, brief flash) are important clues. Even seemingly minor observations can help a professional make a diagnosis.

If you see rapid breathing, loss of equilibrium, multiple fish affected, or sudden death, seek immediate professional help from a koi veterinarian. Do not delay while trying to diagnose on your own.
