The best there is! We are very choosey and these are the best of the best. These have the most orange coverage with no more than15% white on these.
Premium: If we didn't have a Select grade,
you would think these are the most colorful Koi in the world. Amount
of white ranges from no more than 20%-40%.
Classic: If you prefer a fish with more white on it,
these are for you. The white areas range from 50%-70% of the fish.
We've been working with our Koi Lines and selling tens of thousands of them to breeders and hatcheries all over the world since 1983 - longer than anyone else! Angels Plus pioneered the development of Koi and hopes to continue for many years into the future. The color on our breeding stock is unsurpassed! In addition, most also have a percentage of wild blood in them.
A brief note about Red Koi. There are no red koi - anywhere. There are fish that are a reddish orange color, but since the degree of redness is unpredictable, we prefer not to use the word red in our descriptions. As for our lines, you will be hard pressed to find koi anywhere that have more intensity of color or greater reddish tones on average than our fish. Still, all juveniles will appear orange and most adults will be more orange than red looking.
We first saw orange on the caudal of our Koi in 2009. We now have a good percentage of offspring expressing this trait. We have pairs together that should produce an even higher percentage. The first two photos below are a breeding pair. The third is just an average adult coming out of this line with the beginnings of caudal color. Many are much better.
This is a fish with a very complex color genetic makeup. The only known gene interactions are from Gold Marble and Stripeless alleles. There is great variability in the expression of orange pigment, but all the genes involved is not known. The requirements to get good expression are not completely understood. A non-stressing environment is very important and foods containing carotenoids are also necessary in developing and maintaining color. Angelfish cannot produce orange pigment. They can only get it from their food. So, if your foods do not contain carotenoids, your koi will have no orange. Don't worry too much about the foods, since most commonly available fish foods contain a good amount of these carotenoids. We recommend freeze dried plankton, freeze dried brine shrimp, krill meal and a good color flake.
It appears that orange coverage is controlled primarily by genetics but also influenced by environment. The intensity of orange appears to be influenced more by environment. Koi with great orange intensity are not as likely to get as intense in water conditions that are not ideal. Our extensive tests have shown that great coverage of orange comes primarily from good genetics and high intensity is more a matter of excellent care and a little luck - having good water and discovering which foods tend to work best. There are probably some breeders feeding a color enhancing substance that is not natural in foods. You will find it difficult to replicate their results. We only feed our own products available in our Supply Store - with all natural color enhancing foods.
Cautions: Keep these things in mind when looking at photos of Koi on the internet: Representing the color on Koi is a very tricky thing. First, camera hardware and software that interprets color, varies greatly. Camera flashes can both wash out color and in some instances, greatly enhance it. Un-calibrated monitors show colors in many different shades and photo editing software can manipulate photos to look tremendously different from real-life appearances. Also, the spectrum of the light source on the aquarium will greatly affect the look of the fish. Overall, internet photos can be very deceiving. We do our best to represent our fish the way we see them in our tanks. When preparing photos, we do it on calibrated monitors, but it doesn't mean that your monitor will reproduce it the same way, or that your aquarium lighting will reflect the colors in the same way as ours.
In addition to the above problems, the color can fade under stress. In general, the younger they are, the less intense the color will be, even on very well cared for fish in ideal water. It fades somewhat just catching them in a net. Shipping causes it to fade, aggressive fish chasing them, overfeeding, a tank that frightens them, too many plants that deplete oxygen at night, breeding stress and many other stresses can cause the color to fade. When you received shipped-Koi, the color when received won't be as intense as when they were shipped. Also, some people are just unlucky. They have water, that for whatever reason, simply will not produce the best color in their Koi. They can receive fish with great intensity, but will themselves never be able to reproduce it in their own fry.
In general, the color gets more intense as the fish age. At the same time the percentage of coverage generally goes down a bit as the fish matures. Adults that are 100% orange (except where there is black) are still fairly rare at this time from most breeders. We however are getting quite a few from a couple superb pairs.
Koi are not the easiest fish to work with in regards to color. For those who do everything right and have great water, they can seem simple. For the unlucky and inexperienced, it can seem as if the color is artificial and they're being duped by the seller. This is why we recommend buying fish that show good color at the time you get them. If they're tiny and you are the one who must put the color on them, you may find out that they never color-up.
