Caring for koi fish will require thoughtfulness and some TLC. Koi fish tend to live longer lives, most of them even outlive their owners! So, establishing the perfect feeding routine for koi is very important. Just the act of feeding your fish will depend on a few different factors. To find the right type of feed for your koi, consider the following:
Koi Are Cold Water Fish
You’ll feed the cold water fish less than the warm water fish. For this reason, you must maintain a schedule for feedings to make sure you’re not overfeeding your koi fish.
How Old Are Your Koi Fish?
Smaller, younger fish vs. larger, older fish? Smaller food items such as pellets or flakes are better suited for young fish, while chunks of foods will be more appropriate for older fish.
The Koi Fish Diet
What kind of food to feed kori fish? Let’s take a closer look! Koi fish are omnivores, meaning they will eat both plant and animal materials, but they prosper on a vegetarian diet. Commercial, processed pet food should be the foundation of your fish’s diet. Make sure your purchase explicitly says koi fish food. Both young and old, your fish can benefit from occasional treats of wheat germ, lettuce, squash, and other assorted fruits and veggies. Once in a while you may want to feed your fish live treats like earthworms or prawns.
Feedings Per Day
Because Koi fish do not have stomachs and they cannot eat large amounts of food, spreading small meals throughout the day is optimal for the health of your fish in warmer waters.
The temperature of your pond or aquarium will dictate the type of food and how often you feed your fish.
- Less than 50ºF – don’t feed them
- 50-55 ºF – 2-3 times per week
- 55 – 59 ºF – 4-5 times per week if hungry
- 59 ºF – once a day, 6 days per week
- 60-65 ºF – once a day, every day
- 65-72 ºF – once to twice per day
- 72-80 ºF – 3 to 4 times per day.
The colder the water, the lower protein/high carbohydrate your fish’s diet will be. As water temperatures approach 60ºF or higher, your fish will require a higher protein/lower carbohydrate diet that includes more pellets.
