In fact, one of the main attractions that Koi hold for pond owners is the great variety of colors that they display. An even greater attraction is the idea of owning a fish that can literally change colors right before one’s eyes as the Black Koi can!

Koi pond owners need to be careful since it is quite easy to fall in love with with the wide variety of colors that the Koi offers. That is why many owners will end up purchasing too many fish, thus overcrowding their ponds and negatively affecting their Koi’s environment and health.

The Japanese have been patient in developing the Koi. Over the years their breeding has produced numerous colors and more pattern combinations than can be mentioned in one short article. Using water temperature and diet they turned the common carp, with only one or two colors, into a glorious and diversly hued creature. It was an almost magical transformation!

Black Koi come in many variations

The first Black Koi species that mutated were called Magoi. They appeared to be black when you stood above them looking down, but they were actually a bronze color. Magoi blood is being sought after for breeding purposes because of the Magoi’s larger size. Breeders are hoping to hasten growth and maximize size of their Koi through these efforts.

Seasonal conditions, diet and water temperature can fluctuate and affect the color of all the Koi species. The Matsukawabake Koi is a Black Koi with white areas on it’s body. This Koi has been known to change back and forth from completely white, to black and back to white depending only on water temperature. This is a thrill to observe as most Koi coloration will only dull or brighten as conditions change.

In Japan “Karasu” means “crow”. The Karasu Koi has a black body and fins and can also have an orange or white belly. It is also one of the most ancient species.

Koi fish are popular in both indoor and outdoor ponds throughout the world. Their life span is generally from 25 to 35 years although some have been recorded to have lived as long as 200 years!

People seek out Koi because of their ease of maintenance, the colors they offer and the relationship that grows over time. The Black Koi is particularly popular primarily because of their ability to change color right in front of your eyes!

Koi can learn to eat from your hand!

There is a wide variety of Koi fish food available. How do you decide what to feed your precious Koi?

For starters Koi are voracious eaters, consuming almost anything that comes their way, so it’s up to you as their caretaker to provide your fish with a balanced and nutritious diet.

You have the option of feeding a commercially available food, live insects, or a combination of both these items. In addition you can (and sometimes should)  feed occasional treats, fresh foods and nutritional supplements.

Koi fish are omnivores, meaning that they will consume both plant and animal matter, and their prefence runs towards larvae and aquatic insects. Many Koi pond owners either minimize or do not include plant life in their ponds because of their desire to have the Koi themselves be the main focal point.

Another reason they leave plants out of the equation is the enthusiasm with which Koi fish devour any edible in sight, often tipping over and destroying aquatic vegetation in the process! So…if you are one of those who leave the plant life out of your pond you MUST provide your Koi with adequate nutrition.

Make sure to choose a good quality Koi fish food.

The most common and convenient type of Koi fish food is manufactured dry foods made especially for Koi. They come in many different forms including pellets, granules, tablets, chunks and flakes. These products are easily stored, relatively inexpensive, easy to feed and contain sufficient nutrients.

When deciding which type and size to feed you need to take into consideration the age and size of your fish and even the time of year. The best Koi fish food for the summer months will contain more protein than the foods you feed in the cooler months when your Koi are less active. It should go without saying that you will want to choose smaller size pellets for smaller and younger fish and larger pellets or chunks for larger fish.

Many Koi owners like to use additional supplements to enhance the colors of their fish. In theory this works but take into consideration that the red color pattens in Koi are determined genetically. If the red fades then supplementation will not restore it even though the supplement may contain the raw ingredients necessary for color enhancement.

Supplements do improve the overall health of your Koi and do boost their immune systems. Commercial Koi fish food preparations incorporate some supplementation into their recipes. However new and more effective products have been developed in powder form and can be mixed with your current Koi fish food. Just make sure you do your research and aren’t overfeeding any particular supplement as too much of even a good thing can be toxic to your fish.
