Frequently Asked Questions (FAQs)

1. How many times do you feed a koi fish?

How Often to Feed your Koi Fish. We recommend that you feed your fish once a day. This will provide enough nutrients for healthy fish and a healthy pond. Feeding them too often can put an excess amount of nutrients into your pond which can cause algae issues.

2. How do you feed 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.

3. What food makes koi grow faster?

For the best growth, koi should be fed a balanced diet composed of 35 to 40% protein, coming from sources, such as bloodworms, shrimpmeal, fishmeal and other aquatic sources.

4. Can koi eat goldfish food?

The answer is yes. In fact just about every brand of goldfish food says it is OK for Koi and pond fish (other types of carp). So if you are feeding Shubunkins, Comets or Fantails, pond food or Koi food is fine to feed.
