Here are best answers from quora also on what do koi fish eat

  Koi pets are going to eat what you give them – hopefully, healthy koi food and also what they can catch/find in their pond – that’s good.

What you feed them:

  • Packaged koi food – Store bought/mail ordered – which is a quality and properly mixed food pellets for koi, maybe with color enhancers – check the ingredients list
  • Whole wheat bread – useful for between orders of packaged koi food! They love it, will gobble it up – you don’t like the ends/crusts becomes a treat for your koi – but not for a steady diet.
  • What you can catch for them, ie: They love earthworms! They are not used to getting food from the sky like this so you’ll usually find the more observant koi of your pond nabbing these as they come wiggling down. Also try butter lettuce broken up for them. Some people will give them cuts of watermelon, not sure of the nutritional value, probably more of an occasional treat.
  • Some people will actually make their own koi food in a blender and freeze it, google it. But please research to make sure the mix is a balanced diet.

What they find:

  • If you have a well established and healthy pond, their should be a layer of “green algae fuzz” all across the pond structure surface. You’ll see koi grazing on this all day and probably catching whatever tiny critters are within also. Take mason jar full of pond water and you’ll be surprised of all the things wiggling around in there.
  • Mosquito larvae – and that’s a good thing!
  • They generally aren’t too good at grabbing a dragonfly and random flies hitting the pond surface – just too hard for them to see – especially after easily learning to recognize and hear big food pellets hitting the surface. Just a side note, as with Pavlov tests, my koi would start jumping when they heard the back screen door open. Or when I came home late from work they began to respond to flashlights – mealtime! Added note: Make sure to add some “koi proof” pond plants – more places for pond creatures and stray pond food to be found – keeps life for koi interesting.
  • Not as common, but if there is a spawn the koi will “cannibalize” on the freshly laid eggs. Putting salmon eggs on fishhooks as a young boy made more sense after seeing that.

In conclusion please note that home koi ponds are extremely condensed versions of a natural pond habitat. Proper feeding and filtration are required or your koi friends/pets will suffer.

In memory of “Hoover” – a real munch mouth! – She was my first koi, a friendly kohaku (red spots on white) and the first to eat out of my hand. – Steve Garson

A koi’s diet consist of six main building blocks. It includes proteins, fats, carbs, fiber, vitamins, and minerals.

Proteins are essential for growth. A young koi needs more protein than the older one.

Unsaturated fats are beneficial to koi in small amounts – about 5 to 8% of their total diet.

Regarding carbs, a koi’s diet should contain 30-40% of carbs.

Don’t feed them koi food made from rice, wheat, and corn as these foods contain too many carbs.

The fiber helps the koi’s digestion while vitamins and minerals are also essential for their health as koi fish need vitamins B, C, A, D, and K. Minerals such as iron, copper, iodine, and magnesium are aid for their growth and development.

Just a friendly reminder, when you’re going to feed your koi fish, do not overfeed them as it can be lethal to your fishes. More tips on taking care of koi fish here.

ANYTHING and EVERYTHING that they can fit in their mouth! Lol

I had two koi in my pond a few years ago that by the end of the summer had grow not to be 13” And 15” inches long .

And one day I saw a little bird fly over and land in the pond and started to bath himself…

next thing I saw was this poor little bird being yanked under the water by his feet! And after the 2/3rd dunk

I ran over to the pond and had to slap the side Of the plastic to get them to finally let go.

So don’t think for one min that they won’t at least try to eat anything and everything in there environment:)
