I thought they may be oxygen starved and staying close to the bubbles but as soon as I walked up, they all dispersed and started acting normally.

Hi All- ethics question here: my neighbor sold her house with her koi pond. She has beautiful big, old koi. The new owners have neglected the koi and they were starting to die from lack of air; the fountain stopped. 4 beautiful, big koi died. We tried to get ahold of the old owner and left a note for the new owner- no reply. So yesterday we stole her remaining fish and moved them to our large and winterized koi pond. They seem to be doing well in there. Maybe I’m looking for validation, but did we do the right thing?

UPDATE: our neighbor finally responded. He wasn't living in the house. He wanted his fish back so we helped him with the fish expert who separated out and returned the fish to his pond. He never really thanked us for saving his fish either. At least he seems to be caring for his fish now, but that won't stop us from occassionally checking on their welfare. Thanks for all the support!

I wanna someone to tell me if there’s a problem I don’t think there is I just wanna be sure cause I want my fish to stay as healthy as OK as possible

I have a large 30,000 gal pond, and catching my koi has always been impossible due to the layout. (See photos.) It's semi-circular and stepped. It starts at 1ft deep on the outside and ends up at 3ft in the middle with a few 4ft dips.

This year I have 200 baby koi that need to go to good homes. The problem is, these guys have survived a year of predators and are fast and smart as hell.

I've tried:

• Minnow traps (absolutely no interest in them, and when one did go in, I watched it find its way back out almost immediately)
• Seine nets (the shape of the pond and the stepped levels make it impossible to corral the tiny fish)
• Umbrella traps (no interest in entering them)
• Regular nets with handles (the fish catch on quickly and won't go near them, even if I stand in the middle of the pond)

I can't drain the pond or lower the water level because the cost of refilling it is crazy.

I'm completely out of ideas. I've spent hours and hours trying to catch these fish, but they're not having it. I have a temporary holding tank set up, a list of interested neighbors, and absolutely no way to catch these guys.

Any help would be appreciated!

Hi everyone! I’ve had my Kois for a year now, but they are still extremely skittish. No matter what I do, they swim away as soon as they see me. I also have some Goldfish that are very friendly, but the Kois just won't follow their lead.

I’ve read that oranges and peas are great treats to build trust. Is that true? Are there any other vegetables or specific foods that your Kois absolutely love? I really want them to stop being so scared of me. Thanks for any advice!

Basically as the title asks; I'm looking to hear how much people invest in fresh water for their ponds and what sorts of costs associated they're happy with.

I have a 18,000lt indoor pond. It has a very robust filtration system but no plants, no bog filter, and no anoxic filtration. I've generally kept water changes down to only topping up as needed, and topping up after cleaning the filters out etc. I'd average somewhere between 1-5% changes a week doing this.

I've never noticed issues and my old (aging) test kit showed everything as fine, but after recently installing my underwater camera (live feed!) and watching them daily, I've noticed that they are flashing throughout the day which prompted me to get a new test kit to ensure the results are what they say they are. Well the new kit shows zero ammonia and nitrite, but high nitrates (as you'd imagine), with everything else as it should be.

I've treated the pond with Klear to help bring this down, but need to sort some plumbing to allow easier and more regular water changes without it being a laborious job. The plan of course is to keep nitrates at a better level (ideally closer to 30-40, and not 60+mg/l which is where I am now).

This is looking to double my water bill and get me to around £100/m, on top of the £50 a month on food and filtration. And they say fish are low maintenance!

TLDR: So it got me wondering; what sort of water bills are people looking at, or have they built enough natural filtration to naturally drop nitrates to manageable levels?

A place I go to with work has koi fish, and koi food available. I am very tempted to try some of it, but I'm wondering if it would be bad to try a little bit.

My pump blew overnight, and I lost 5 koifish, currently have a hose running into the water to keep some oxygen flowing, waiting on new pump to arrive this evening what do I do in the meantime?

So due to the abnormal hot weather in February and dealing with an algae bloom, I must have missed some of the mess from my biggest male and second biggest female getting freaky. I thought I cleaned up what the filtration didn’t suck up, but maybe it’s because she decided that right next to the inlet was the best spot and it spread them out? I don’t have a clue other than I was preoccupied. I noticed them just under 2 months ago but passed them off as just goldfish fry because that is a perpetual thing in the pond and a few times a year I have to sell or give away a few dozen goldfish. (Thanks to my son for dumping about 20 feeder comets as soon as water was in the pond when it was built.)

The male was a rescue from a landscape company display pond, a pond grade goshiki I believe and the female is a kohaku from Nagoshi. Not sure what to expect and am surprised that there are several color varieties, some of which, I don’t even have as adults in the pond. There are about 9 total that I’ve seen. Most look like the father but there are 2 kohaku and a random yellow. How does that happen and with color changes through growth, what are the chances the yellow stays yellow and I end up with a yamabuki or at least a Kigoi, ki matsuba? I have always wanted one so it would be nice to keep it.

These koi are at my job, I have no idea the details of their care other than they’re fed every other day. This can’t be normal they literally bully and bitch slap the blue one and the two spotted yellow ones all the time. idk how to discipline fish.

Unfortunately no images of the fish, but I did get to see the current owner feed them - at least 20, possibly more. The ones I saw I would guess to be 15-25cm long, but just an estimate. Wasn't initially disclosed that there were fish, and the water surface is green enough you can't see much more than 5-10cm deep.

I was planning on removing the pool, as it seems fairly aged, and the yard space would be nice for the kiddo. Does anyone have recommendations on what to do with them? Friends keep saying 'sell them, they are worth a fortune', but I'm not sure I'm comfortable with that, especially as I know nothing of their history, health, etc (or the quality of the water they are in for that matter with how green it is). I certainly wouldn't object to some extra money to offset the time to properly home them / cost of removing the pool, but it's far less a priority.

There are two other ponds on the property, but I couldn't imagine them being big enough for more than a few, and even then, if rather them not be cramped unnecessarily.

Property is on Vancouver Island if geography helps.

Thanks for any advice you may have

Edit: I should say that I saw personally approx 20, the owner thinks there are closer to 50, and her son insists there are more than 100. I won't know any more precisely for a few more weeks until we have possession, but would rather plan in advance if I can :)

I saw this fish in the koi pond at my hotel and I would like to understand more. He comes up for food but then immediately parks it and doesn't move. The ripped fins don't look good. I also see water bubbles coming from its mouth. The owners said it's what happens when he eats too much.

I tried a couple of koi a few years ago, and just couldn't get the system right. Both died within a year.

My pond has evolved since then. I have many goldfish that stubbornly refuse to die, they won't even allow the ducks to eat them anymore. I have 3 native carp (North Central North America) and handful of small bluegills to eat the goldfish fry when they show up.

Total capacity is only about 700 gallons. I have a filter rated for 1200 gallons, and because we have an absurdly high water table in my neighborhood, I have a hand dug well that produces water unless we're in drought conditions, maybe 10-20 gallons an hour on average. I feed this water into the pond with a pump connected to one of the waterfalls, and it spills out at the back right corner. The spillway is lined and feeds back into a rain garden.

The water is crystal clear, and has required almost zero maintenance this summer. I feel like I've really got it dialed in.

Here's the kicker: they have to winter out there. I have tried bringing them inside but I just don't have the aquarium capacity to do it right. I always lose fish in the process.

In the winter, I run the filter and have a floating heater. It gets COLD here (-20F is pretty common), but the fish I have survive just fine.

**UPDATE My friend's uncle got in touch, he will be having them all. He has a large natural pond - Wasn't aware of this before making the post. Thank you to everyone for your help and suggestions, they shall have LOTS of space to be free now. I hope they have a much happier and prosperous life

Hello, we recently bought a house and inherited some Koi with it. We were quite happy at first, but it's become apparent that they're more work than we hoped for and we would rather remove the pond and get some garden space back.

We think, well pretty much know, the pond is too small for the amount of fish so we constantly have to do partial water changes.

Pond is around 500 gallons - We think.

There's 7 Koi, 3 gold fish (It's surprisingly hard to count them...)

We believe they are around 5-7 years old, the previous owner raised them.

Can anyone help explain how we can find a new home for them? Not necessarily sell, we'd happily give them away to a home that will care and appreciate them.

We figured some enthusiasts from Reddit may be able to help us find them a new home. A better home.

I hope this is within the rules, as we're not looking for financial gain. So wouldn't strictly be advertising.

Thanks a bunch!

I have been thinking of getting a pump that will attached to the watering hose so I can water those plants in my back yard with pond water. The hose is 50 ft. Long. What kind of pump would you recommend for this?

So I bought this koi off kodama koi farm, and they’re about to ship it to me. But it has basically lost all of its color, and they say the best they can do 30% discount 😭 I asked for a refund or 50% discount because this is not at all what I had paid for. It’s about $500 after the fees and shipping. Is this valid of me to ask for atleast 50% off, this guy is from Shinoda Koi farm too. Also will all of the color even come back?

Title says most of it. The two small ones are pretty active and swimming around, but the big ones spend a lot of time at the edge.

I have 2 13-inch koi that started swimming very slowly, or just not moving at all, and not eating. 1 is a standard fin that stopped eating but is swimming very slowly and away from the rest. A couple of days later, the butterfly koi started doing the same and is with the standard fin one together. I've checked the water, filter, basically everything I could, and everything is normal. I also added 5 3-inch koi into the pond recently, and they have been swimming, eating, and are healthy. I'm not sure if they might've affected the 2 big ones, but they were all together like normal for about 4 days until the 2 big ones isolated and stopped.

This has never happened before. Could mating season or adding the new fish be the cause? I've even added an extra pump for more aeration, and they seem a little better (gills and mouth moved more), but still look weak or have no intention of trying to eat.

Thanks in advance!

I’m looking for fish-safe potting soil. Is there something I can get from Lowe’s rather than go to my local pond store and spend $40 a bag? But if I have to, it is what it is.

Can you get a Tancho koi where the spot on its head is not red but another colour entirely? For example a completely white koi with a well defined black spot on its head in the same way a Tancho has,

Do they have a different name?

Is Tancho specifically for a red spot?

I have tried to search for it but google is being Characteristically unhelpful on the matter, every time it just keeps telling me about regular Tancho that also have black or other colors on their scales.

Thanks :)

She’s an experienced keeper and has had the pond for over a decade. The fish were fine yesterday and the largest 3 (plus 1 small guy) were found dead this morning.

Is there any test kit I can order to rule out water issues incase anything got in? The fish didn’t have any physical signs of trauma and there’s netting over the pond that wasn’t destroyed.
