LA
At a foot or so, koi start getting some great colors.  Note the barbels.

LA
Even at six inches, many koi have attractive colors and eye-catching sparkles.

Origins:  Carp came from China.  The Japanese gave carp their beautiful colors -- nishikigoi or fancy koi.  USA added the long “butterfly” fins.  Most affordable koi are US-reared. We get quite a few from Indonesia and Malaysia..

LA
Attack of the hungry koi.  "Feeding frenzy" comes to mind.  Koi belong outside.

Appeal:  Seeing a pool of adult koi impresses anyone (even non-fishkeepers) with their colors and grace in the water.  Koi are also impressive at feeding time – actually rearing their snouts up out of the water to feed -- looking like a pack of submarines searching for the Bismarck.

 

LA
Little two-inch koi cost much less but have little color.

LA
If you can find a little koi that looks this good, take him home with you.

Start Small:  Few fish fans can afford to buy an adult SQ (Show Quality) koi.  After a year or so, these guys start getting pricey.  Little koi sell at much more affordable prices.

LA
Larger koi with brighter colors naturally cost more.  Outside, they color up even more.

Size:  Koi grow huge – as big as a river carp (they are still carp).  For this reason, we recommend keeping them in outdoor ponds.  They will bump into and break aquarium filter stems and heaters.

Doitsu:  Koi with large over-sized scales are called Doitsu by the Japanese.  We call them German carp here in the Mississippi valley.  Sprechen sie Deutsche?  Doitsu equals Deutsche which equals German.  Bieru equals Bier which equals beer.  “Look for the cognates” as Herr Professor Vox used to say.  End of our Japanese/German language lesson for today.  Nicht wahr?

Wintering:  If your pool is three to four feet deep, your koi will winter better outdoors.  If you bring yours inside, keep them as cool as possible.  Filter them well and feed them very little.

City Regs:  If you maintain a backyard pool deeper than 18 inches in most cities, you need a six-foot fence to keep kids out.  Koi ponds attract kids from several blocks around.

Threats:  During the day, fish-eating birds and kids are the biggest threat to koi.  At night, owls and raccoons pose the biggest threat.  In all practicality, overfeeding and poor water quality present the biggest problems.

LA
Koi get too big to keep in tanks.  They dig up the gravel and make a mess.

LA
Big koi break your heaters and your filter stems.

Space Requirements:  If you can’t give them 50 to100 gallons of water per koi, stick to goldfish.  Koi need lots of room to grow.  They also like to jump out of aquariums and small ponds.

LA
You can see koi barbels in the other pix, but this was more fun.

LA
You can see the barbels very well here.

 

LA
Here's another fun koi pic we couldn't resist.  Finger-licking good.

Foods:  Last year (written in ’99), every company and their brother and sister got into the pond business.  You won’t have any trouble finding good koi foods.  We stock koi foods from Taiwan and Germany, as well as several USA koi foods.  Yes, koi will eat Cheerios and bread.  Koi also love any plants they find in their water -- especially duckweed (and, unhappily, including water lilies).  Koi ignore water hyacinths.  Well, sometimes they tear them up for the fun of it, but they usually won't eat them.

LA
The more, the hungrier.

Mixers:  Frogs and snails mix well.  Goldfish sort of mix with koi but get elbowed out of the way at feeding time.  Koi are very enthusiastic chow hounds.

Spawning:  Anytime your pond warms up 15o in the spring, your koi start wallowing in the shallows.  See Carp for spawning details.  Female koi spew eggs  in unbelievable amounts.  They probably eat most of them.  Only a few hundred survive from each spawn (and that’s plenty).

Fry Food:  Powdered fry food works fine.  Newly hatched brine shrimp work better.  Even if you feed your koi fry nothing, some will survive. 

LA
Never lose your balance when feeding koi.

Summary:  Relaxing next to a pool of inquisitive koi, flipping them a pellet,  enjoying their antics, sipping a lemonade … What’s not to like?  LA

Sorry to bother you with corrections, but I have some for your koi page. Doitsu   koi come in 2 varieties: those without any scales and those with large "mirror scales." Those with mirror scales have less vivid color than those with no scales at all. Also about koi size and color: The maximum size I've seen in person was 1 meter 8 cm (about four feet). Also this size can be reached at three years of age. After one  year, some of my koi grew to a size of 55 cm (2 feet). About color: the Japanese can tell if koi will be show quality while the koi are still fry (in a batch of thousands of babies there will only be one or two high quality koi). The color is already   mostly developed in small koi. except for where you can see some secondary coloring, e.g., pinkish coloring next to red or blue/grey color. Thanks for your time!
PS. GREAT SITE!!!!

Hi, First off, kudos on having such a WONDERFUL website!  I stumbled 
across it while googling possibilities for new fish.  Your attention to detail and incredible amounts of knowledge are a great resource. The creative writing keeps things entertaining and enjoyable. Excellent job!
I just wanted to point out an observation regarding the sentences  "You need to wipe your tank front more often with comet goldfish.  Add a Plecostomus to help keep your glass clean." on the page http://
www.aqualandpetsplus.com/Live%20Food,%20Goldfish.htm

It is well documented (google will reveal many instances) that COMMON 
plecos tend to really enjoy sucking the slime coating off of common  goldfish and comets.  I don't know about Koi, though.  I personally had to remove a 10 inch Pleco from a pair of foot long Comets (indoor) due to this problem.  I kept noticing a scale missing from the comets here and there... could not for the life of me figure out what was going on, but one night as I happened to be passing by the tank a few minutes after lights out, I saw the pleco dart full speed at a comet and drill it in the side, followed by the unmistakable glimmer of two shiny scales floating free.  I got on the magic internet, and sure enough, plenty of people have had the same 
problem.  Apparently, it is the same problem as you described with 
livebearers -- the Pleco really likes the taste of the slime coating on the goldfish.  I don't think they mean any harm, and I never experienced any long-term problems in the comets as a result (the scales grow back in a few weeks to a couple of months), but without action, I'm sure that the goldies would be much more susceptible to illness due to the raw spots on their sides.
In fairness, there are some goldfish/pleco keepers who swear that they've never had a problem, and I don't doubt that, but there certainly are a number of us who have experienced this behavior.
Interestingly, many goldfish owners report that bristlenose plecos and other similar (mainly smaller) species have not shown the same behavior.  Beats me as to why, though.
Just wanted to bring this to your attention!  Hope all is well,

A:  Right you are.  And hungry plecos are even more likely to nail koi.  I'm adding your comments to my comet page.  LA
