What does “Goromo” mean?

Goromo Koi, also called Koromo, received his name from the Japanese word “Koromo,” which means “clothed” or “robed.” It references how their blue tint “robes” their Hi markings. In English, people often use both Goromo and Koromo to talk about these koi, though Goromo has no definite meaning we can find. Then, we will use both words in our conversation, which usually means the same!

Goromo Koi Varieties: 

Goromo Koi has come to five recognized varieties, and although there may be more depending on their parents, these are the main ones. If you see a pattern in Kohaku, such as Inazuma, Sandan, Tancho, or Marutan, you can also find it in Goromo Koi. It is interesting to know that real Goromo may not be KinGinRin (metallic), though they can be Doitsu.

• Ai Goromo (Blue Goromo):

Ai Goromo is a common type. The name derives from “AI,” meaning blue or indigo. Instead of having blue on the sides of its red scales, it is inside the scales, often in a semicircle. The pattern     is ordered and neat, mainly along their back, a little like in Asagi. No blue should be on the head of this type.

• Budo Goromo (Grapes Goromo):

Budo Goromo is a type of AI Goromo. “Budo” means grapes in Japanese. Here, blue (or sometimes black) groups on red scales, forming grape-like clusters. Occasionally, the red is shown, giving a purple-like look. This type is rare.

• Goromo Sanke/Sanshoku:

A Goromo Sanke has one Asagi and one Sanke or Sanshoku parent. They can have many Sanke patterns such as tango or aka. These Goromos usually have a typical blue pattern, with some black combined (Sumi) anywhere on the body or head.

• Goromo Showa:

Goromo Showa is a result of mixing parent Asagi and a parent showa. In this type, the blue pattern may not limit itself to red scales (Hi) and can be found in other body parts.

• Sumi Goromo (Black Goromo):

Sumi Goromo is most rare type. Instead of blue, they have black patterns on the sides of their red scales. Black can be thick, almost covering the red, or it can be random and scattered, unlike AI Goromo. Sometimes, red is shown in some places.

Goromo Koi Care Tips:

Maintaining the well-being of your Goromo Koi involves some key considerations:

• Goromo water quality:

• Visual signs, such as color changes, indicate water problems.
• Avoid high diets in color enhancers to prevent yellow dye or unwanted orange spots.
• Unfavorable water hardness and pH can lead to unwanted black marks.
• Ideal water parameters: 50 °F to 78 °F, pH 7.5–8.5, oxygen above 7 ppm, low salinity (0.05-0.15 ppt), and 75–100 ppm of total dissolved solids.

• Goromo temperature:

• The water temperature influences the color of the koi; the coldest water leads to darker tones, while warmer water can cause less vibrant colors.
• Goromo develops better at temperatures between 50 °F to 78 °F (10 °C–25 °C).
• Different depths of ponds allow Koi to regulate body temperature naturally.

• Goromo diet:

• Balanced nutrition is essential for Goromo’s health.
• Colorful Goromo benefits from diets with spirulina, krill, and over 30% protein for adequate growth.
• Enhance blue coloration with astaxanthin, spirulina, or guanine supplements.

How to breed Goromo Koi?

Breeding Goromo Koi can be challenging because of unpredictable genetics, especially the unique blue color. Success is more likely for experienced breeders familiar with the Koi family tree. Blue tone, usually on red scales, increases complexity, demanding experience to achieve the desired results even with two Goromo parents.

Cost of Goromo Koi:

Goromo Koi are becoming more popular, and their unique blue color and complex breeding make them more demanding and expensive. Well, there are fewer considerations to understand while buying Goromo Koi.

Juvenile Goromo: 

• They are younger Goromo, and you will find them at an affordable price.
• Prices for juveniles can vary from a couple of hundred dollars or pounds.

Adult Goromo:

• They can be a little pricier as they are grown-up Goromos.
• You will find them for several hundred to several thousand dollars.

However, other common goromos, such as AI Goromo, are usually more budget-friendly, making them an accessible choice for many KOI lovers.

On the other hand, rare Goromo, such as Sumi Goromo, can cost more, especially adult ones, often reaching a few thousand dollars; even juveniles can cost closer to 1,000 dollars.

Moreover, some specific patterns, such as Tancho Goromo, are placed at the upper end of the price scale.

Considerations:

Many factors influence the price of Goromo Koi, and potential buyers should consider these considerations:

• Prices can highly vary depending on the seller and geographical location.
• Consider buying from reputable breeders who display their credentials. Their cost may be high, but they ensure transparency and reliability in purchasing.
• Using Koi forums to collect breeder feedback can offer important information about their ethical skills and reliability.
