Baby Bottle Feeding Huge Koi


These huge Koi are being fed by a baby bottle. It looks like there are some huge Koi in that pond.

Monday, November 23, 2009

Hi Utsuri

Hi Utsuri
The Hi Utsuri is a red and black Koi. It is a popular breed and is found in most ponds all over the world. When choosing a Hi Utsuri, look for a deep red color with an interesting black pattern. A slash of black coloring across is the face is very desirable.

Tancho Goshiki

Tancho Goshiki
Another rare Koi. It is hard to find one of these. The Tancho Goshiki is a red, white, grey and black Koi with grey shading. This is a fine example with a nearly perfect Maruten Spot.

Platinum Ogon

Platinum Ogon
The Platinum Ogon is a metallic white Koi. Most are bred with the Gin Rin scales to make them appear even more shiny. These are popular in poorly filtered ponds, since they stand out in murky water.

Shusui

Shusui
The Shusui it a scaleless Asagi. It has a baby blue color that fades to white when it gets older. There is a row of large scales that run along the top of the body from the back of the head to the tail fin. Shusuis are known for their deep and interesting red pattern of color.

Chagoi Utsuri

Chagoi Utsuri
This is a rare Koi with black and brown coloring. It is created by cross-breeding a Chagoi with a Utsuri colored Koi.

Jumbo Asagi

Jumbo Asagi
This Asagi is blue/grey in color with red covering the lower half of its body.

Aka Matsuba


The Aka Matsuba is a red Koi with grey shading in the scales.

Champion Showa

Chamipon Showa
This Showa took grand Champion in the 2006 Niigata Koi Breeder Show.

How To Make Koi Grow Faster


How long does it take a koi to be 12 inches? - Roderick

There are several factors that affect the speed of growth:
  • Genetics
  • Environment
  • Feeding
Some Koi grow faster than others.

There really isn't anything that you can do for this. You can buy from a breeder that has shown fast growth in his fish for several generations and hope that your will have that gene too.

Koi grow faster in large ponds.

Mud Pond
The Japanese breeders grow out their tosai in huge three to five acre ponds that are very deep. These mud ponds are enormous compared to the little garden ponds that most people have. The average Koi person has a pond that is only a few thousand gallons. Not many people have the room or the budget for a large pond in their backyard.

Temperatures affect Koi growth.

Koi do their growing in the summer. The abundance of nutrition and the warmer temperatures accelerates their growth to its maximum potential.

The more you feed a Koi, the faster it will grow.


Koi need high protein food to maximize their growth. Feeding several times a day is a good idea to make your Koi grow faster (just don't overtax your filter system). You'll want to feed your Koi a high quality, high protein food. Just be careful not to over-feed your Koi. You can make your fishes fat and it will deform their body conformation.

In ideal conditions, it usually takes a couple years for them to get about 12 inches in length. If you have a small pond in live in a cold climate, it will take longer. If you have a large pond, feed a lot and you live in a warm climate, then it could take less time. Every Koi is different, some start out as slow growers and then speed up as they get older. Some start out as fast growers, and then slow down after a couple years of age.

How to Draw A Koi Fish

Watch these video clips to lean how to draw a Koi fish. Chris Garver teaches all the fine points and details on drawing the fish.





Tuesday, November 17, 2009

How long can koi be out of water and survive?

They can be out of the water for about 15 minutes with minimal damage. The key factor in keeping them alive is if their gills stay moist, which allows them to breathe. If their gills dry up, they suffocate.

Koi are jumpy when they get in a new place. It is a good idea to keep the tank or the pond covered with a net. It is also a good idea to provide some cover for them to hide under.

Winterizing Koi

Are koi gonna die during the cold winter?

These are generally the requirements to overwinter your Koi outside during the wintertime:
  • A pond that is at least 4 feet deep
  • A de-icer or heater system to keep the ice open
  • A decent amount of aeration, so your Koi get a good amount of oxygen in the water
  • It's clean, no fallen leaves or fish waste to decompose at the bottom
  • It's not heavily stocked
If your pond meets these requirments, then your Koi fish will probably survive the winter. If you really don't want to leave them out for the winter, you can also build or buy and indoor tank for them to live in during the winter. Make sure it has adequate:
  • Room for you Koi
  • Aeration
  • Filtration

Head Shaking


What does it mean when a Koi shakes its head violently? -Daniel

It's listening to heavy metal music. Just kidding! Seriously, a Koi shakes its head when it is having health problems. Usually a parasitic infestation. The best thing to do is call a veterinarian so they can come out and take a scraping of the slime coat of the Koi to study under a microscope. Then they will be able to identify what parasite is causing the problems for your Koi. The vet will then prescribe the correct treatment, so you can get rid of the parasites and make your Koi healthy again. It's no fun to have a sick Koi.

Haijiro


The Haijiro Koi is a black fish with white fin tips.

How big do Koi get?

Jumbo Koi
Most Koi will usually grow to about 18 inches long. However, the special jumbo Koi can get up to 3 and a half feet long. These monsters usually weigh about 60 to seventy pounds and are very rare. Most people will never get to see a Koi that is that big.

Curved Fish Tank

Koi Fish Acrylic Painting


Here is a painting of three butterfly Koi. The varieties are:
  • Kikusui
  • Kohaku
  • Hariwake

Life Span


What is the length span of a Koi fishes life? -Time

Most Koi live for 20 to 30 years. Some will live longer lives, some will live shorter lives.

The two largest factors that will affect their life span are:
  • Genetics
  • Environment
Usually Koi with good genes and a good blood line will live longer than a Koi that is inbred.

Environmental factors include:
  • Water Quality
  • Stress
  • Location
  • Predators
To keep the water clean, make sure you have a decent filter system. To provide a low stress environment, keep pets and children from disturbing the pond. Make sure your pond has some shade, Koi don't really like full sunshine. Predators will cut your Koi's lifespan short, keep them out of the pond.

Treating Infected Scales


In this video, which was produced in Germany, we have a Koi that has an infection under some scales. It is a Doitsu Aka Matsuba. The fish is caught and put in a tub. Some anesthetic is added to the tub to cal the fish down. The infected scales are removed and the the wound is debrided with Iodine. The Koi is then put back in a tub with well oxygenated pond water to wake him back up from the affects of the anesthesia. It is then placed back in the pond and rocked back and forth to further help to wake him up. Hopefully, it will make a full recovery.

Female Butterfly Koi Egg Bound

I have a 8 year hold female Butterfly Koi. We believe she may be egg bound. She has stopped eating for about a week now. I check her pond several times a day and there is this milky gel like substance floating around in the water. It appears to be coming from her. I clean it out and when she moves around more appears. She has been staying on the bottom not really moving much. She is by herself. What can I do to help her? - Reda

The best thing you can do is have a vet come out and see if they can perform an operation to remove the tumor. I don't ever recall hearing about a Koi that recovered from being egg bound all by itself.

Do Koi like waterfalls?


Yes they do!

Waterfalls provide Koi with:
  • aeration
  • warmth
  • a nice current

Waterfalls also provide people with:
  • a nice view
  • soothing background sounds
  • relaxation

Difference Between Indoor and Ourdoor Temp

Thermometer
What is the difference from indoor and outdoor temperature, with the thermostat indoor reading 70 degree? -Devaughn

Well, it depends on what time of the year it is. If it is wintertime, the difference will be great. If it is summertime, there probably won't be much difference.

When not in direct sunlight, Koi ponds tend to be a few degrees cooler than the ambient temperature. Especially if the pond is large. If a small pond is hit by direct sunlight most of the day, then it can get hotter than the ambient temperature. It is important to consider this if you have a small pond since it can hurt your fish by getting too hot.

Ulcer Treatment

Koi Ulcer
Hello what is the best treatment for ulcers on Koi carp? I have been told to use salt. Is that ok to use? Many thanks. - Darby

I would set up a hospital tank. Add about a pound of salt per hundred gallons of water. The salt will irritate the Koi, but don't worry, the only thing it will do is cause their slime coat to grow thicker. It is ok to use salt, but it probably won't take care of the ulcer on its own.

Treatments for ulcers include: antibiotic injections, debriding, medicated food and Tricide-Neo.

Injections require a prescription from a veterinarian. You will need to have the vet come out and perform a susceptibility test, to determine what antibiotic will get rid of the infection that is causing the ulcer. There has been much abuse over the years with antibiotics, so there plenty of strains of bacteria that are resistant to multiple antibiotics. You will also need to purchase needles and anesthesia (you can't inject a fish that is flopping around). You can have the vet teach you how to inject or you can have them do it for you. Either way, its gonna cost some money. If you have valuable Koi that's sick, you should have a vet look at it anyways.

Debriding should be done by a vet, since if it is done wrong, it can seriously damage your Koi. It involves cleaning out the dead tissue in the ulcer with iodine. It can speed up healing, but should be used with an antibiotic regimen.

Medicated food works, but only if your Koi are eating. Most of the time when Koi get sick, they stop eating. Some people feed medicated food to their fish all the time, the only thing this does is it helps create stronger bacteria strains that are more resistant to antibiotics.

The single best treatment is the Tricide-Neo dip. It comes in either a one gallon mix or a five gallon mix packet. You mix it with the correct amount of distilled water in a tub. Then put your Koi with the ulcer in the solution for about three to five minutes. You then put your Koi in a tub with hospital tank water for about five minutes to rinse off any Tricide-Neo that is still on the fish. Repeat this process every other day for a total of three treatments.

Tricide-Neo is a potentiated antibiotic, which means that it is able to kill off even resistant bacteria strains. You can order it from a number of places and no prescription is required. Just Google Tricide-Neo to find a dealer. It has a long shelf life, so you can order it and keep it in stock in your Koi supplies (it lasts even if it is mixed with distilled water, it's good until it turns yellow and smells fishy).

Feeding Time


This large Showa is hungry. Watch him gobble up a bunch of Koi food in this video.

Average Koi Pond Cost

My family wants to get a koi pond. One of our friends also has one, so he can help. The only problem is the money. How much does the average koi pond cost? - Jake

I assume you are building it yourselves, to save on labor costs.

It depends on the size and amount of filtration the pond will have. A small pond with high end filtration equipment will probably cost the same as a medium or large pond that is either poorly filtered or has DIY (Do It Yourself) filtration.

DIY filtration usually involves a large container, like a barrel, that is filled with bioballs. A high end filter system usually involves a pressurized bead filter, UV sterilizer and a protein skimmer.

DIY filtration costs less but involves much, much more maintenance than equipment that you can buy from a dealer. How much more maintenance? Up to about 10 times more. Don't think that's true? Cleaning a pressurized bead filter takes about 15 minutes a week. Pressurized bead filters backwash just like a pool filter, you only need to turn a valve to clean them. Cleaning a barrel full of bioballs takes about an hour (You will get covered in smelly pond scum and fish waste).

Here, it's broken down for you:

DIY Filtration
More time consuming - less money

Pressurized Bead Filter
More money - less time consuming

You will get tired of getting covered in goo every few days eventually.

Green Water
There really isn't a safe way to add a DIY UV light to your pond. You need a purchase a manufactured unit from a dealer. UV lights prevent algae from growing by sterilizing them, so the water in your pond stays clear.

Some people add large amounts of barley to their pond as a cheap alternative. A bacteria that grows in the bales kills algea. Who wants to have a bunch of bales of barley in your pond? No one. The bacteria that kills the algae takes two months to grow, so if you live in a cooler climate you better start the pond up early!

Dissolved Organic Compounds

Their is only one decent protein skimmer for a Koi pond, it's called a Clarity Protein Skimmer. They will get very small particles of waste that are dissolved in the pond water. It's almost impossible to do a DIY version of one of these, your better off buying one.

DIY filtration won't have a warranty or a guarantee that it will be adequate for your pond. When you purchase a filter from a dealer, they will help you size the equipment for your pond. Manufactured equipment can have warranties up to 4 years or more!

Here's the pricing, for a small (1,200 gallon), medium (3,000 gallon) or large (5,000 gallon) pond, with high end filtration and DIY filtration:

DIY Filtration:
Small: $1,500.00
Medium: $3,000.00
Large: $5,000.00

High End Filtration:
Small: $2,500.00
Medium: $4,000.00
Large: $7,500.00

Why are the Fry Ugly

I have both koi and goldfish in a 2,500 gal. pond. They were very active during breeding season. The babies are about 8 weeks old now, but 75 of them look just like minnows. Dark gray/brown on top with a dark stripe down the middle and a white belly (just like a minnow). The other 50 babies are pale orange. Why do they look just like minnows? - Gingrich

The majority of fry revert back to the natural color of their ancestors, which is why the Japanese breeders cull the majority of their fish. The carp that Koi came from are a dark black color.

Hiding

How do I train my koi to not run and hide every time I come around. I tried to not feed them for 3 days but they still hide till I leave. - Steve

Are you moving around a lot when your by them? Try remaining still and giving them some food. Keep at it and then start moving around a little when you are feeding them. Soon enough they will associate your presence with getting fed, so they shouldn't be shy.

Fall Good Time To Buy Koi?

Dear Sir,

I have just completed my backyard pond. Its end of August now in Boston and Fall is marching on. I have scoped some sites selling 5-8 inch koi and I am wondering if I should go ahead and populate my pond with the small koi now or is it the wrong time of the year and wait for spring? I have an aireator, flowing water, filter installed for water hygiene.

Thank you

OAK


You can certainly find some great pricing on Koi at this time of the year. Although most dealers stock will have been picked through very thoroughly.

Keep in mind though, you will only be able to appreciate your Koi for only a couple months before you'll have to winterize your pond. Make sure you know how to keep Koi outdoors during the wintertime too (unless you plan on keeping them in a tank indoors). Winter and spring are very hard on Koi.

Make sure whoever you buy your Koi from quarantines them when they first arrive and tests for the KHV virus.

Side fins closed not protruding - Derek

Sounds like your fish is sick with an infection. Have a vet take a scape with a microscope slide and a tissue swab for a bacteria susceptibility test, so you know what antibiotic to treat with.

True Colors

How old do Koi need to be before having their true colors? - Tony

It depends on what type you are talking about. Some Koi, like a Yamabuki Ogon, have their color as soon as they are born. Other Koi, like the Showa, take years for their color to develop.

Blacky Baby Fry

Hello, can you help me? My Koi carp mated 3 mouths ago and I have loads of fry. They are about one inch long now, but they are still all blacky gray color. When do they get their colors? The koi carp that bred were all different colors. I have no black Koi in my pond. Will they change? - Darby

Ninety five percent of fry that Koi produce have little or no color. Unfortunately, he fry in your pond probably fall into that percentage. Koi have their colors as soon as they emerge from their eggs. Some change, but since yours were from a random spawning, they will probably stay black.

Can too much clay do any harm to koi?

Yes, adding too much bentonite (Koi clay) to the pond can clog the filter system, so your water quality will go down.

How to Breed Koi


It is a very laborious process.

You need good brood stock, which will cost you several hundred thousand dollars or decades of careful breeding. You will also need equipment, facilities and a great staff. You also need a lot of time.

The oyagoi (parents) are placed in ponds that are full of spawning matting. For a few hours, the female will ready itself to release the eggs onto the spawning matting. When she ready to expel the eggs, you'll need to coax them out of her into a bowl. The male is then taken out of the pond, anesthetized, and then has his sperm is extracted. When the sperm and eggs are gathered, they are mixed together to achieve fertilization.

The eggs are then put on the spawning matting that is in the ponds. This must be done carefully, so they get attached to the matting correctly.

Within a few days, your Koi will hatch and you will see the fry swimming around in the pond.

Now you'll need to move them into a large pond and feed them a decent food that is full of packed with nutrients.

When they grow large enough, you'll need to cull them. This involves sitting for days on end while you sort through tens of thousands of baby Koi. You'll whittle them down until you are left with a few thousand of your best fry.

After the culling, the fry will go into a mud pond to grow until they are large enough to sell.

You'll repeat this process over the years as your Koi grow. You'll remove the ones who lose their color or have deformities. You'll also separate out some Tategoi, Koi which have future potential but don't look the greatest right now.

The process can get very complicated, here's what you have to be knowledgeable in:
  • Fish Husbandry - You'll need to know how to take care of thousands of fish and keep them healthy. One bad disease outbreak and years of work will vanish (not literally). You'll also need to know how to filter your display ponds.
  • Management - You'll need to know how to keep your employees in line.
  • Selling - It doesn't matter what quality of Koi you produce if you can't sell them.
  • Importing/Exporting - Why limit yourself, but you do need to keep up on all that paperwork.
  • Funding - It can take up to a few years to produce a single quality Koi, what will you do for cash flow in the meantime?
  • Construction - Those mud ponds aren't going to build and maintain themselves.

Tons of Eggs

My Koi just let out massive amounts of eggs in a 150 gallon pond. What can I do with them? - Leroy

You can either raise the fry or you can try removing the eggs from your pond. You can also let your Koi eat them, which they tend do do anyways.

If you let the fry grow, your going to need a place for them to live eventually. Hundreds of Koi can't live in a 150 gallon pond.

Butterfly Listing

I have a 4 inch butterfly Koi that is listing to it's left side. It swims around fine, but i am concerned because this has only been noticed in the last week. what can I do to help restore this fish to full health? I have given all the fish (about 15 total) the first treatment of potassium permanganate with no visible distress noted and plan to give two more treatments. - Harry

Sounds like your Koi has an internal problem that keeps it from swimming normally. You can check to see if it has an ulcer or parasites that are bothering it. These may be what is causing it to list. If it isn't a parasite or an ulcer, the only thing you can do is wait for it to correct itself.

Three Koi Sick

Three Japanese Koi keep laying on there side as if there dead. All other fish common carp and Koi all ok. Japanese koi losing the bright color but are still feeding ok. - Martin

Sounds like your new Koi are sick. Koi loose their color when they get an infection. You need to get in touch with a veterinarian that specializes in Koi health. They will be able to diagnose what is wrong with your Koi.

Dropsy or Eggs?


I have a Koi that appeared to have dropsy. We treated the pond and it didn't seem to work. All of the sudden the fish is back to normal size so I assume this was eggs but the fish was like this all summer. It also has a half dollar size wound that came up on its side after whatever was there was released. Do you have any ideas on what could be going on? I have salted the pond and I am using Melafix and Pimafix. I am very much an amateur at this so any professional advice you could give would be appreciated. - Claudia

It could have been eggs that caused your Koi to swell up. Usually dropsy is a sign of organ failure, Koi with dropsy rarely live past a few days. It is even rarer if a Koi comes out of dropy.

It's good that you salted the pond, this will make your Koi's slime coat thicker. If that wound doesn't heal up, try some Tricide-Neo. It is a potentiated antibiotic, so it is effective with resistant bacteria.

5000 Gallon Pond


It looks like there are about 20 medium sized Koi in this pond. It has a nice small waterfall falling near the middle of it.

Treating An Ulcer


They take the fish out of the pond and treat it with some sort of medicine that's in a pressurized can. I guess that's how they do it in Holland. Interesting way of applying medicine anyways.

Holland Koi Show 2009


Here is the video from Holland's 2009 Koi Show. There are tons of beautiful Koi in all of the tubs.

Feed Baby Koi


Baby Koi need to eat just like their larger counterparts. They feed on decapsulated brine shrimp, infusoria, or crushed Koi food (it will be powder). You'll need to feed them several times a day. Make sure you have pristine water quality too, the fry are sensitive to water chemistry.

Koi whirlwind feeding frenzy!! Second batch 8-21-2009


From AiNishikigoi on youtube:
This here is the product of several pairs of Japanese Koi bred in separate holding tanks. The frys were then raised for several weeks in their respective tanks before I combined them all together for ease of transportation and maintenance. They are at about 1.5-2.5'' in length as of 8-21-2009. This batch is the second of the year, the first one was produced in early May and was the product of a Sakai male x Hoshikin Kohaku female (video will be uploaded after the last cull).

Within the mix will be a varied amount of Gosanke, Utsurimono, Bekko, Asagi, Goromo, Ogon, and a few other variations. There is also a diverse representation of doitsu as well (Shusui). The quality of the genes should all be there as a few of the parents were from Momotaro, Shinoda, Marudo, Yamamatsu-Matsunosuke, Ofuchi, and other high quality breeders and farms. Hopefully all this hard work would yield a few show-worthy koi. But at the least, they are very adorable!! I must admit though, they do grow fast :-(

I was compelled to record this as they gathered in 'whirlwind' formation during feeding time. I thought it was pretty cool and wanted to share with everyone. I am located in Sacramento and San Francisco. If any one is interested in the koi or need general information regarding pond care, let me know! I'm always available to help. Thanks!


Very truly yours,

Dan

Attilatomi's Pond


Here is a video clip of a nice Koi pond.

Green Water


Green water is caused by algae. Algae feed off of the waste that the filter converts into Nitrate. If you have a ton of fish in your pond, you'll have a ton of Nitrate and that will fuel an algae bloom. The best way to get rid of algae is to use a correctly sized UV light. A UV will sterilize the algae, so it can't take over your pond. Your pond will clear up within a week of adding a UV light.

How to rid your pond of argulus?

Argulus
Argulus, or fish louse is a parasite with an oval body and a proboscis mouth that it uses to feed off you Koi. You can pick them off your Koi with a tweezers. To eradicate them from your pond, check out the entry in the book Koi Health and Disease by Dr. Erik Johnson.

Keep Koi Indoors?

Could I keep a Koi indoors? Do Koi do okay by themselves, or do they need to be in a group? How big of a tank would it need? - Nicole

Yes, you can keep Koi indoors. Make sure they have all the basics: filtration, aeration, sunlight, etc. The tank will need to be fairly sizable, since Koi can grow up to three feet in length. A solarium is the best place for an indoor Koi pond/tank. 1,500 gallons would probably be the minimum size of a tank that would permanently house Koi.

It doesn't have to be an aquarium, I've seen a lot of cool tanks made out of concrete or wood. The best ones have a Polyurea liner.

They do need to be in a group. If you have only one Koi, it will be very skittish and afraid.

Just look at this poor fish, he is all alone and his tank is way, way to small. Please don't ever do this, it's cruel:

Jumbo Koi Swimming Video

Jumping Behavior

Do big pond Koi often jump out of water for bugs , etc? - Kathy

Yes they do! Koi jump if they see a bug on the surface and they swim at it very fast. They will also jump if they are startled.

Gold Color

I have a black and white Koi that is changing to gold. The koi is about 8 years old. Is this natural or is this a disease?

It is probably natural. The gold color is coming out with age, unless your fish starts acting funny, there's no need to worry.

Parrot Fish


I just got a Koi fish in my tank with one 12 inch parrot fish and it won't stop biting the Koi's tail what can I do about this? - Jason

You put a docile fish in a tank with an aggressive one. The only solution is to separate the fish.

Salt Water

Can Koi fish live in a salty water? - Loi

They can live in water with a small salt concentration, about 1 pound per 100 gallons. People typically use 3 to 5 pounds per gallon when treating parasites. You have to be careful and test your salt levels frequently. Water evaporates and salt doesn't, so its concentration will increase. If you add salt, make sure it is pure and doesn't have any additives like Iodine.

You can remove salt by doing water changes.

Pond Pump Went Out

My pump went out during the night, how long will my koi live without a pump? - Angela

You Koi will live as long as these things don't happen:
  • They run out of oxygen
  • Ammonia levels get toxic enough to poison your fish
A lot of people rely on a waterfall to aerate the water. So if your pumps stops working, your Koi lose their source of oxygen.

The pump runs the filter, which relies on bacteria to filter the water. The bacteria need food (Ammonia) to survive, and without the pump running, they lose their source of food. After about 12 hours, the Nitrifying bacteria will start to die off. If you lose the colony on your filter, it will take a while for it to come back.

The longest a pond system should be shut off should be no more than 10 hours in an emergency.

Jumping


One of the Koi fish in my pond jumped out of the water like a dolphin. He jumped twice. Can you tell me why he did it? - John

There are a couple reasons why your Koi was jumping:
  • It could have been going after a bug.
  • It could have had an itch, they don't have arms to scratch with, so any external force will do the job.

Breeding Age

How old do the Koi have to be before they spawn....or breed? We've had ours for a little over a month and we now have a minimum of 17 babies....we have three 5-6" koi and two 4" koi.... - Tonya

Koi usually have to be at least 2 years old to spawn. Usually they are a little larger than yours, but you probably have small ones...

Sanke Broken Tail


I have a Female Sanke Koi. Her tail appears bent in one area as if it were broken and her bottom rear fin had a a blood clot in it. The tail is healing and growing back but the bend appears permanent. I could not find the answer anywhere on this. Would appreciate any response. Anthony CA

Spawning Signs

How will I know if my fish are spawning and where would they spawn? My Koi carp seem to be bullying another fish... - Angie

Your fish will be bumping into eachother, a lot. You will notice behavior for several hours. They will spawn in plant material, their eggs need something to attach to.
