White Koi - The Classic Symbol of Elegance
The Classic Icon of Elegance
Nothing epitomizes sublime beauty quite like the White Koi. Valued for its purity in form & color, the Platinum Ogon, as it is more commonly referred to amongst enthusiasts, has turned out to be somewhat of a "standard" for many koi ponds worldwide. This popularity is due partly to the fact that they are able to grow rapidly and are surprisingly easy to see in the murky water of poorly filtered ponds. They stand out beautifully alongside the host of colors of other koi varieties.
Throughout the earliest days of breeding and cross-breeding Koi in Japan, there were generally only one or two colors on hand, so, as Koi breeding gained popularity around the world, the range and diversity of colors and traits increased dramatically. Today there is an ever-increasing assortment of color and pattern combos available, ranging from red, black, white, green, blue and yellow.
To completely appreciate the different varieties of Koi Fish, one needs to develop a comprehension of the various classifications that each group falls into. Each class has standards to ascertain which group they belong to, but generally speaking, each group has a particular level of acceptable diversity.
White koi originally appeared back in 1963, most likely from cross-breeding Kigoi (lemon non-metallic) with the grayish-silver (metallic) Nezu Ogon.
When learning about Koi varieties, it's interesting to note a particular point of differentiation. Each variety usually has a Doitsu (scale-less) version and a Gin Rin (sparkly) scaled version.
Most Platinum Ogon are bred with the Gin Rin scales to make them appear shinier. Gin Rin scales have a pigmented reflective sheen that produces a glimmering effect much like that of cut diamonds. To meet the requirements as a Gin Rin, a Koi must have at least 20 scales which is the acceptable minimum requirement.
Ogon refers to koi of one solid color. Whilst known colors include red, orange, platinum, yellow and cream, the two most popular colors are the Platinum Ogon (white) and the Yamabuki Ogon (yellow). A desirable attribute of the Ogon are sizeable fins because they offset the single color body. The color of any Ogon should be consistent all over the body of the fish.
An additional interesting point is that as the majority of the fish's pigment is on the top section of the fish, the light is able to reflect off their backs, highlighting their bright and beautiful color combinations. For this reason, Koi are generally best seen from above, as in a pond.
Although all koi are classified as Cyprinus carpio, selective breeding and cross-breeding has resulted in many varieties of koi, each based on varying levels of scalation, color, and patterning.
As a preliminary guide for the amateur Koi devotee, it is perhaps useful to provide a few words in the Japanese Koi vocabulary to make the task of understanding Koi Classification a little less overwhelming. An illustration of how this Japanese terminology works is shown in the following example variations:
Aka Bekko - A red Koi with black patches
Shiro Bekko - A white Koi with black patches
Ki Bekko - A yellow (ki) Koi with black patches
Doitsu Bekko - This is a scale less version of the above

My Black Koi fish has white stuff on his fin and forehead. What do I do?
The whiteness on the fin and forehead appeared about a week ago and I have tried treating it with an algae neutralizer. Unfortunately, it didn't seem to work very well.
I have isolated him from my other fish for a period of 24 hours and treated him with a stress reliever hoping for a change. There was no change.
Now, it justs sits at the bottom of the fish tank occasionaly moving. His eating habits has changed he now eats considerably less than normal.

What should I do?
if your fish has lasted more than Two days and hasn't gotten worse, I will say it isn't ich.
Also, is your koi all black? It is very rare to have a truley all black Koi since the purpose of breeding koi is for their bright brilliant colors, most black breeds sold are Hajiro (Utsuri Mono) or a form of Hajiro koi which will develop white markings on forehead (usually a pattern) and on the fins as they age. also, kumonryu koi can and do change their patterns and colors with the changing seasons and water temperatures. Do you know the TYPE of black koi you have. ONLY if it is a Cyprinus carpio is it truley a black koi. (this is important) Carpio black koi need a minimum of 500 to 1,000 gallons of pond water per fish to thrive. they are a very fine fish with very high needs. This could be the start of your problem if it truly is a black koi.
However, if it a Hajiro Koi or other color breed can just be having the colors come in. How old is your fish and what is the temperature of your pond? Due to the no change in the fish for 2 days good or bad other than lethargic, you need to be sure of the TYPE of koi you actually have.
Also, where is your koi being kept now? Is there lots of dissolved oxygen getting into the water? Is he eating plants or green veggies?
Koi have specific feeding requirements one of which are plants to nibble on in the ponds as well as supplementing the food source with a high protein low fat food. Greens like peas, lettuce, spinach, greenbeans as well as oranges and watermellons are a wonderfull diet addition to your koi.
When you look at your koi, can you tell if the white patches are fuzzy looking or are they just scale color like someone dumped bleach on them?
If they are more fuzzy and have not infested the gills, it could be a fungus. Also, algae neutralizer and stress medicines will not help your fish.
Feel free to email me and I will try to help further. find out the TYPE of koi you have.
