| Feed nutrition | 15% | The intake of pigment raw materials such as carotenoids directly affects body color |
| health status | 5% | Illness or stress may cause temporary fading |

| Overall whitish | long term lack of light | Gradually increase light time |
5. Expert opinions and netizens’ experiences
Professor Li, an expert from the China Ornamental Fish Association, pointed out: "Goldfish discoloration is a normal physiological phenomenon, but sudden and drastic color changes often indicate health problems.
