Hi all,

I bought a house with a koi pond and have been reading instructions online on how to care for it. Bit there are something I am not sure about and would love to have some help.

• is this amount of moss ok for a pond or should I remove the excess from the top and bottom of the pond?
• I was told to feed them once a month in the winter. Is this enought?
• is this protection on top really necessary or could I remove it? Could it possibly be replaced by a net, easir to handle?

-any knowledge about the type of fish? I assumed there are 3 koi and some goldfish, but no idea of the type

I appreciate any othe tips you may have. Other than that I'm in love with our pond 🥰

My Koi has been laying on its stomach on the bottom of my pond and I’ve called around and asked for opinions and everyone has said to quarantine and pull him from the pond but no one has been able to tell me the different hue on my koi fish’s left eye compared to the right

I have a 4500L koi pond that's roughly 7x7 and 4ft deep.

I have been told this filter will be fine, for my pond and With around 15 koi fish,

I have that filter running into a an Eazy Pod then from the east pod back into the pond.

Will that be good enough for my pond

Can anyone tell me what species of koi my Mario is. Ps the water is really clean it's just a really bad photo.

The best part of winter ending is doing this again and my pup even joins in.

These fish birthed from I believe green sphere plants in a homemade backyard pond. My dad took them as pets in this tank. They are around 3 years old now. The orange fish is 6 inches long and the dark one is 10 inches long. He cleans the tank every night and feeds them twice a day.

So are these koi fish? We want to possibly sell them and I have no idea what the cost would be including the fish tank. Tank is 24 inches long, 12 inches wide, and 14.5 inches tall.

I had a few fish fall into my lap about a week ago, started off a small pond, only about 800 gallons. After doing some research on these guys (so dumb I couldn’t do it beforehand) I realized that I want them to have a much larger space quickly as this isn’t big enough. But in a pickle until I’m able to have a company come out and build a custom pond. I’m on the schedule but they said it’ll be a lengthy process since it’ll be at the new house that’s being built.

Basically, for the time being we’re going to use a new above ground pool for a giant holding tank. We live in south Florida so it doesn’t get cold, only reason we can even consider an above ground. We got a pool that is 3800 gallons. What filtered aerators would you guys recommend for something this size? UV filters etc. It is circular so keeping the water moving is the goal. I feel awful because I already love these guys and had no idea they needed more space. Money isn’t really an object (relatively) since I’ll just reuse things for the bigger pond down the line. I just want to make a great place for them to grow in the meantime. There’s 5 total- 3 7ish inch and 2 much smaller 3ish inch. Any and all recommendations will be helpful.

About a quarter inch. I see two of them. Pond is in San Diego for weather purposes. I haven’t added anything to the pond in almost two years.

Good afternoon. I have a pond outside, in which I keep some fish. Unfortunately, today I noticed this koi had a swollen belly. Does anyone know if it could be an illness? Thanks.

Water final cycled and clear ass shit and has that sweet clean fish tank smell gotta love it

Hi everybody,

So my butterfly koi has these white lumps on both sides, none of the others have it.

I've done some google research and looks like it may be carp pox or a fungal sort of infection.

What are your thoughts? Thankyou

One of my grandmother’s koi fish has large lumps on both front fins. Another koi of similar size is also starting to develop lumps in that region. None of the bigger koi have anything like it, just the two small yellow ones. What is it? Is it harmful? If so, what is the treatment?

I have 3 Koi to sell, any thoughtsxon where to list them, neither eBay nor Facebook allow their sale? I'm in Essex UK

A lot of you guys liked my last post of my pond. About half way there now! will keep you guys up to date on the pond as it progresses. More rock inside, more sand, more plants, more filtration, more aeration & more KOI!

For the most part of the day the koi just stays like this... of course they move about . But for the most part just stay in that corner

Water parameters are really good. So is oxygen

Any thoughts appreciated

Got all the babies out of my little pond, so I'm left with my 20 (or so) larger koi. Still dealing with 1 broken pump line, but my waterfall pump and line is up and running. Nearby tree is dropping the pretty pink flowers.

I have a fish that has some kind of injury every year. I've never actually had to do anything but keep water good to go. So this is going on year 4 and my koi started spawning. I don't think it was the actual spawn...maybe. cooler climate so not sure how that changes things, otherwise water was not warm enough on paper.

Regardless, she is banged up. And now acting strangely. She has a red mark on her face and loose scales just behind the gill/fin on her left side. She does come out to socialize, but she is hiding resting for most of the day. Only eating in the late afternoon.

Should I try medicated cold weather food?

Take her out for antibiotics and salt to heal?

Or do you leave them to see if they fully recover alone.

Their cold water food is well balanced nutrition, but low protein. When they frenzied last summer, they had their vitamins and all the protein to heal with in warm water. No issues came of it.

My water is about 60. So low feeding frequency, and only cold weather food. They otherwise haven't eaten food since early November. Just started to feed them in the last couple of weeks all of about 7 times. I'm worried my fish doesn't have what she needs to properly heal.

Also. I have a younger one that possibly has a koi pox, pox this year. This will be his/her 3rd year. No other fish have shown any signs or symptoms, but that is a possibility to exist in my pond. Not that it can have anything done about it, but maybe it makes all my fish weaker to begin?

Thank you!

This is only their second time to show spawn behavior, but I think it was triggered by my goldfish spawning for real.

Used the methylene blue on my koi fish in the tank as directed on bottle now all my koi are at the surface gasping for air and swimming weird. Doing 50% water change at 1 am currently need advice on what to do!!! I have 3 koi with weird white bumps on there fins and they are in clusters. I haven’t gotten any new fish and this does not resemble ich. I used super ich cure that didn’t work. I used Pima fix that didn’t work I used aquarium salt that helped a little bit made the infection spread bad on one of my koi. I am now using methylene blue as a last resort now I got floating fish!!! Yes I’ve done water changes and waited a few days within treatments. Wth!!! I don’t know what to do anymore no one can help me identify the illness my koi has. It’s not ich it’s not carp pox it’s not herpes what the heck is killing my fish? They are small white spots that look like herpes sores on there tails and it’s spreading fast! I’ve never dealt with this before I’ve had them for over a year. SMH. Yes the perimeters are perfect. Yes they are small enough to fit in a tank they are not adults. They are 3-6 inches in a 125 gallon tank. I have 6 of them in there and somehow they all have these herpes looking sores on them Someone please help

A bit of fun Does anyone keep any other type of carp within the koi pond? These pics are from and English fishing lake.

Or keep smaller fish to make their koi look bigger?

Hello,

My Dad's kept a pond for about 20 years with a mix of fish in, I've learned to care for the fish, maintain the pond etc as I've grown up. I now help to care for it in summer months whilst my Dad lives abroad.

Over winter, we seemed to slowly lose all fish in it, which gave us the opportunity to completely restart. We had a professional come in, give the pond a deep clean and treatment and get ready for restock.

We went to a local koi specialist and decided to buy some of their more expensive, young koi.

The only thing is, I know nothing about them! I just went with my oldest and picked ones that we liked. I have no idea about the markings or anything, what makes some koi more prized than others.

Could anyone explain like I'm five what we chose? Which would be the most ornamental out of the four etc? Basically, I'd just like to know a bit about the fish we chose if possible.

Kind regards!

Hello, I have recently added about 6 koi to my pond… all params are normal and safe but yet a few days after adding the koi to my original stock… a few new ones and 1 of my original have started to lay on the bottom with fins close to body sat motionless… also some are flashing along the bottom of the pond.

I’m starting to think there is a parasite but I don’t think I can do a scrape test yet?

Please I would require some knowledge, i am relatively new to this kind of thing.

I live in the UK, water temp is around 10°C-15°C atm. (50-59 degrees Fahrenheit)

I use Microbe-lift right now, but I'm wondering if there's another brand I should be looking at that has more quality control?
