Frequently Asked Questions (FAQs)
1. How many times do you feed a koi fish?

Koi and goldfish can be fed a regular, all-season formula when temperatures are above 65°F. When water temperatures are below 65°F but above 50°F, you'll need to switch to an easily digestible food. Wheat germ-based formulas are the most popular choice, like Blue Ridge Cool Water Wheat Koi and Goldfish Food.
