How many times have you heard to not feed table scraps to your pets? That’s still true—but there is one major exception—koi! Koi do love fish treats from the pet store, but they are just common fish food. Your koi are craving more, so why not share some of your favorites with your fish?
Here are 8 healthy koi treats sure to please!

healthy koi treats
Watermelon – Koi like watermelon, but not as much as grapefruit. It doesn’t supply a lot of nutrition so keep this snack to a minimum
Cheerios – What child wouldn’t love to share some of their cereal with pond fish? Cheerios are low residue and low nitrogen, making them great healthy koi treats. We’ve found that koi tend to prefer Honey Nut Cheerios.
Sardines–You might be thinking it’s cannibalistic for koi to eat sardines. Regardless, they’re a healthy koi snack to serve in the summer. Thawed, chopped, frozen sardines are from saltwater which means they’re less likely to carry parasites applicable to koi. Feed sardines to your koi in moderation.
Orange segments – Fruit is yummy and a healthy koi treat!! Big fish will take mandarin orange segments right out of your hand! It’s a great party trick to impress your friends and family. Larger seedless oranges can be cut into quarters and fed to the fish, as well.
Grapefruit – Cut the grapefruit into quarters before feeding to your koi. The sections float and your fish will be attracted at once. Make sure the skins don’t jam up your pump or skimmer. Also, don’t feed grapefruit to your koi too frequently as the vitamin C acid can scorch their lips and turn them to a pale pink. No harm done, just reduce the amount of grapefruit you feed them. Once per week is plenty.
Peas – Make sure the fish know you’re ready to feed them before you toss the peas into the pond. Peas sink fast and you don’t want uneaten peas polluting your pond. Some experts say the skins are hard to digest but peeling peas can be a tedious task. To make it easy, peel partially frozen peas. Give them a little squeeze and the pea pops right out of the skin and into the pond! Koi seem to really love them – as long as they know they’re there.
Worms – okay, so you probably don’t serve worms at your dinner table, but nevertheless your koi will enjoy earthworms, Georgia reds, night crawlers, pinks, and others. Fresh, active earthworms are well accepted and safe, and when the first koi takes a bite, the rest will quickly catch on.
Romaine lettuce – Nutritionally invisible, but perhaps the least messy of greens for the fish to munch on. Don’t bother with iceberg lettuce. Get the darkest romaine you can find and cut it into six-inch long thin strips.
