You might have thought you were feeding the best food? Or didn't know which one was best? Here's how to tell!

Koi Treats

Koi Treats
Someone said that it would be helpful to write an article on Koi treats. And so I am. But in this article I am only going to comment on what I personally have given my fish. There's a lot out there, how much of it has actually been tried and how much is theory I shudder to think.

Silk worm pupae
Available various places in sealed silver bags, this delicacy drives Koi crazy. Really, really nutty. They love them. I guess when a silkworm gets old and stops making silk, it's "history" and is freeze-dried for Koi. Lip-smacking good, I guess. Fed in abundance, the protein can accumulate a good bit of nitrogen (ammonia) in the water so please check Ammonias if you're going crazy with Silkworm pupae. I never had trouble in warm water but I did feeding SWP in cold water. A little bit every day or two is enough.

Grapefruit
Cut the grapefruit on it's equator (widest latitude) and then again cut those halves into halves. So you have quarters. They float. The fish will be attracted at once. Watch out the skins don't jam up a pump or clog your skimmer. Fed too much, the vitamin C acid will scorch the lips of your fish to a pale pink color, no harm - just back off. Once per week is plenty.

Watermelon
They liked it but not as much as Grapefruit. It doesn't supply much nutrition so I have not done this as much as grapefruit.

Orange slices
Big fish will earnestly take Mandarin orange slices right out of your hand. Very cool, delicious to the fish, I guess, and loaded in Vitamin C. Larger seedless oranges can be cut as Grapefruit [above] and will do as well.

Peas
The pain in the neck to me about these was that they sank fast. And if the Koi didn't see them go in, they miss them on the bottom. So there's the chance of wasting the peas and polluting the pond. So be careful to let the fish know you're there, and "here come the peas" and all that. They say that the peas could be skinned. Yeah, sure, I have time for that, how about you? My Koi liked the peas quite a bit, when they realized they were there. I had a Tancho Goshiki that especially liked the peas which showed me that not all fish are alike, personality-wise.

Romaine
Nutritionally invisible, but perhaps the least messy of "greens" for the fish to munch on if you like them to have something to eat like that. Don't bother with Iceberg lettuce. Get the darkest Romaine you can and cut it into six-inch strips of the thinness suitable for your fish. They will chomp on the thick centerspines of the leaf later.


Hyacinths
Delicious to koi. Cut off the roots because they are a mess!!!! I repeat, cut off the roots. Then fracture the plant so it's barely hanging together and toss it on the pond upside down, foliage in the water. The larger Koi especially will eat the youngest leaves first and then pretty much annihilate the whole plant. Do NOT offer roots because the Koi will rip them up and send them directly to your pump's impeller which will summarily choke to death.

Duckweed
Koi will eat ALL of this. If they can. They love it, so do Goldfish. In REALLY large ponds a balance may be struck where the Koi cannot or will not eat all of it but in a regular 11 x 14 pond Duckweed will be a shortlived commodity. It's easily grown outside their abode in vats, babypools and tubs in a sunny spot with six inches water, fairly well circulated, with a small dead fish, or a handful of Koi food, for fuel.

Worms
Koi eat earthworms, Georgia reds, nightcrawlers, pinks, etc. Some people say that you should drown the worms in water first because the "hazardous soil" is expelled from the worm when it drowns and goes flaccid. Uh, my fish wouldn't eat them dead like that, either. So go figure. Fresh, active earthworms are well accepted and safe after the fish take the necessary half hour to figure them out as food. When the first Koi hits a worm, the rest quickly catch on. It's not taken as immediately as Grapefruit, which is strange. Isn't it?

Fish
Koi can be trained to like fish. A very good friend of mine, named Tom, feeds his Koi thawed Sardines chopped up. Nutritious? YES! And sardines (being from salt water) are less likely to carry parasites applicable to Koi. So, again, in moderation, these treats are okay for Koi. And certainly well enjoyed.

Cheerios
We discussed Cheerios in the winter-feeding section but let me restate that ANY time of year, Koi will appreciate Honey Nut Cheerios as a treat. It is low residue and low nitrogen, what's not to love? A+

Kenzen Koi Food
There's a bunch of people feeding this food and for good reason. It's got a good formulation with a decent price.

Chicken
Yes I did this. It wasn't a smashing success and they left it alone for a little while but I took some fried chicken to the Koi. I ate the fried part (duh) and gave them the white meat, in pinches. They looked at it and swam around it a while and then hit it with pretty good gusto. But it made some debris when they chewed it with their back teeth and wasn't "loved" so I include it here as something they'll take, but not necessarily love.


Is there anything I probably should NOT feed Koi as a treat?
I've heard that grapes can contain some oxalates and that apple seeds contain cyanide. The math on these says that if you got a Koi to eat a cubic meter of grapes or appleseeds in a day's time, said Koi could perish from the crystallization of the oxalates in his kidney. For your information, a Koi that could eat a cubic meter of grapes in a day would measure about forty-two feet long and weigh in at 2,300 pounds. So I would say this:
Dr Johnson's Notes On Koi Treats:
"If you would eat it, and the fish can eat it without it dissolving in, or polluting the pond, try it, and see if they like it. Don't feed any treat so much as to replace their interest in nutritionally complete staple food."
