Recommendations on koi food with large pellets?

[carpe diem]

Does anyone have any recommendations for koi food brands that offer large pellets? All of the higher end food seems to be 0.5 cm (3/16"), and the smaller fish gobble that up immediately. I'd like to be able to mix in some larger pellets for my big guys.

I've been trying Microbe-Lift Big Bites which are about 1 cm. The big koi like that size but are a bit meh on the taste. I also tried clumping some of the smaller pellets together with a bit of fish oil and water (a suggestion I found online), but it leaves an oily residue on the surface that I don't want.

Any suggestions are welcome!

You can always use distilled water soften up some of the smaller pellets put them into a press and then a dehydrator. even the large pellets that i have found i agree still seem small. The little guys can eat them as well to a degree but once they get one there are busy for a while.

currently aquascapes probiotic and Kodama color up large

So mashing them up and reforming then into larger pellets? That seems like a good solution. Would a dehydrator be necessary, or would an oven work? I don't want to lose nutritional value if that's possible; I know probiotics are heat-sensitive. Maybe leaving them to dry overnight would work?
