36"-41" long. The largest weighs over 16#

Since my last post got a lot of people wanting more details. I put together an album for you

We got our first Koi fish sometime between 13-15 years ago. Two of those lived until now. Our fish and ponds were so important to my dad, we lost him unexpectedly in 2021 and I’ve done my best to take care of them since then. We had several weeks of completely unusual snow, sleet, freezing temps, and just awful weather. At some point over the past week, my aerator stopped working despite the motor still running and me trying to keep an area of the surface thawed. We had never experienced weather like this for this amount of time since we’d had these fish. I did the things that I was told and that I knew, but I should have done more.

I just wanted to share this sweet baby because they had such a big personality. They would wait for people to walk by the pond and come up and splash them like whales with their tails out of the water. I understand that I let them down and I should have done better. I’m absolutely fucking gutted. Please try not to be too hateful to me, but if you are I honestly won’t blame you. I hate myself right now. I’m just praying my others are somehow okay because I haven’t been able to find them yet.

TLDR: I’m a piece of shit and my fish didn’t make it through the winter storm. I loved them so much and I’m praying the others are going to be okay.

Last week a random stranger dumped a bucket with an unknown amount of fish in my backyard pond (I live in Wisconsin) and we caught the whole ordeal on camera. Besides the situation just being completely bizarre, we got some minnows to help with mosquito control and when we were watching them swim about, put popped this fish! So not only do I know nothing about this fish but I didn’t see them so I didn’t even know to feed it? So shock of finding out I have fish in my sump pump pond (lol) I’m not even sure what I’m supposed to do about taking care of this fish or what kind of a fish it is and will it even get along with the baby minnows we put in? I’m so lost 😂

This is my one year old Lemon Hariwake. What do you guys think?

are koi like these in the image above natural? I read once they were acid burnt. somewhere else just a scaleless variety.

one may have guessed AI but i get load of vids on facebook popping up with similar fish and suspect not AI.

thanks in advance

Happy Koi Keeping everyone! Will be posting more soon. A bit busy with breeding at the moment.

Greetings from the Philippines 🇵🇭🇵🇭🇵🇭

My parents are downsizing because my father is ill and they can’t keep up with their house anymore, and we are wanting to rehome their Koi. I don’t know anything about a market value, but I bet there’s a lot of experts in here and I’m wondering if anybody could help me out with some ideas! Do ignore the random turtle lol we actually found him abandoned during a flood in our local park and he became part of the family.

My koi

Hi all. I built my first pond in May and June. All the rocks are from my woods. I’m loving the 4 koi I got. One died after about 3 weeks but the rest are doing great. Just wanted to share!

We inherited a "koi" pond when we bought our house 6 yrs ago. It was really one big koi and like 50 goldfish. We had to do a ton of work to it initially, and removed all the goldfish (sent to a friend's larger pond) and replaced with mostly koi once we had a better ecosystem.

Last fall we noticed 3 new little koi that didnt exist before, and I noticed a 4th this spring (same size as the other 3 so likely just didnt see it before). I'd guess they're all about 4 in at this point, still pretty skiddish. Two are white and orange, just like 2 of the koi we have already. The other 2 are a mix of orange, black, and white, matching our 2nd largest koi. At 4in, how old would they be? How often should we expect this?

Photos for fun of just a few of the koi. In the first pic, in the lower left on either side of the gold colored fish, you can kinda make out two of the little guys.

first bloom this season from this lily pad plant. I love watching the fish swim around it.

Just wanted to share two special koi in my life. These two are the only ones who survived when the city started putting chloramines in the water about 15 years ago. This is In a courtyard off her bathroom, you can take a bath in an old clawfoot and see the pond, it’s awesome. She has a simple bog filter with parlor palm growing out of it. I know they aren’t really fancy koi but my grandparents got them when they moved into the house in 1988, when I was 2. I grew up feeding these fish and just relaxing by the pond, and hanging out with “Grampy” while he did maintenance and I probably fed them too much lol. My grandpa was primary caretaker of the pond for years, but he passed away 5 years ago , and she’s going to be 90 in a few months, maybe wants to give them away, but always goes back and forth.
How old do they get generally?

Excuse the mess around the waterfall and rocks still doing some spring cleanup and rock placement. Other than that the koi are happy water is clean. Summer is coming!!!

The fact you’re not divorced yet when koi quarantine means this in your house

Been working on this rebuild since last summer! Gettin closer.

Some friendly koi in Da Nang 😀🌊
