I fast my koi for about 30 days every winter... sound cruel, but ive done so for 10 years. I would alway loose koi in the cold months, or all kinds of health issues... was feeding high protein, way back then. 4Now i fast and use wheat germ from october to march. Have zero sickness and... lovely clear water.
