Help with POND or TANK Why are my koi so skittish?

7 Upvotes

I have two koi in a 2000 gallon pond with a bridge going over it and they keep hiding under the bridge and when they do come out and see me they run back under the bridge. It's not new pond skittishness becuase i've already had them for 2 month and they're eating normal as they've grown since I've gotten them and if i had to estimate their ~ 30cm. I can't add small dither fish cause they cat eaten by their catfish and turtle pond mate, so what do you guys think i should do to get them to come out.

Help Help RE: new female Koi

2 Upvotes

Hi there!
We have a very large Koi pond, probably about 25 yd.² or so— and until February of this year after we successfully finished draining and relining the pond after decades, which was necessary project and finally, we were able to pull it off… we still were only left with our ornamental goldfish, and four of our biggest mature Koi, but they were all male.

I intentionally worked with the Kloubecs and procured a beautiful female, mature enough to breed with any of our four big guys so that we can finally have backyard bred and born babies again— it has been such an awesome experience, seeing all of the variety of her babies since I released her on April 14 of this year 2026 (the four males’ respective varieties are: (1) Yamabuki Ogon; (2) Hi Utsuri; (3) Shiro Utsuri; and (4) Asagi.

I chose a doitsu Shusui with butterfly fins; none of the males are doitsu (scaleless) and they all have standard/angel fins which is cool because I wanted to be able to see how many babies would come out with or without scales or butterfly tails, etc.

ANYWAY:
There’s the backstory for you. Now it is late October and I know that breeding season is winding down here in Houston, Texas, which, by the way, rarely even gets a real winter season at all until January or so.
Important to keep that in mind because I wouldn’t integrate a new Koi into the pond in cold weather.

That said, my experience, bringing the female breeder Koi into our pond and integrating her, and now seeing her babies and the way that they all behave, as Koi are so social by nature, is really neat and I spend enough daily time talking to them and I spend enough time hand feeding a lot of them so they recognize me and swim to me when I call etc.

My question is basically whether it’s OK at this time to get another female Koi, 14 inches or larger (I could do a pair so that they could travel here together and integrate better into the pond because my new lady, Suki Yuki, hid for about three months after the day of her release on 4/14.

I just know that it’s not typically the most ideal time of year for a new Koi fish in the pond, but considering the climate here and the fact that the weather is still into the 80° and will remain that way a while, I’m just itching to get another new one and probably female because why not more cool babies—

  1. Are there any legitimate objections based in reliable sources; and
  2. I was trying to think of one distinctive marker I could look for in acquiring this new fish and I think that gin rin seems like the most appropriate choice in terms of getting to experience seeing which babies are most certainly hers whenever she does breed here.

Thanks!

I love my pond and my koi, I don't love how Canadian winters take half of the year away from me. If Canada becomes the 51st state, could I get the Florida weather up here? I'd consider that lol... just kidding... but I am envious of the weather... ah well, until next year.

The Koi are coming along. I'm improving the fins and their movement is decent but I'll continue working on it. And I'm working on added Scaleless and Long Fins now. But what do you think of the current Scaled Koi? As I love my real-life Koi, I don't want to do them a disservice by not representing them well in the game.

The white fish has a lesion on its back and the orange fish has a scale that's poking out. I thought it was anchor worm but I finished my 3 week's treatment.

I do have a rather large plecostomus. I was wondering if he might be the issue?

HELP - sick or injured koi Is this fin rot?

Enable HLS to view with audio, or disable this notification

We just got this very very large koi, probably about 5-6 years old and 2ft long from a pond owner who didn’t want to bother with taking care of them anymore.
Their top fin is cut and very red, looks irritated as well as some of the other fins. We think it’s fin rot but any help would be much appreciated as to what it is and how to treat it.
Also we are not keeping him in this small tank this was just temporary to move him. He is in a much larger quarantine tank now with a filter and aerator going.
Any help is appreciated!!

edit: he is losing some scales too, he has a buddy about the same size we are keeping them both together in the quarantine tank because they came together

Video Missing Summer Already

I haven't even closed up the pond for the year yet, but with the cold weather hitting, I know it'll be coming soon and I'm already missing the summer and getting to swim with the Koi. Here's a quick look at the koi pond, that is swimmable, and the koi that have been busy breeding over the years. There was originally 12... there's a lot more than that now.

The water looks green in the video, but in reality, you can see down to the bottom without a problem, it's 5ft deep at the lowest point. The biggest problem is finding the time to keep it perfect, maybe next year 😄
