Separate appearance from health

Koi appearance reflects genetics, variety, age, light, and environment; a color description alone does not establish a fish’s health or market value. The article above provides the topic-specific context; use these checks to connect that answer to the actual fish, pond, equipment, or cultural setting in front of you.

• Describe the variety, pattern, scale type, and lighting before judging a change.
• Compare color observations with appetite, swimming, breathing, water tests, and injury signs.
• Use established variety terminology carefully and avoid treating a normal pattern as a disease.
