Latest Medaka Popularity and Recommendations Ranking

Among the more than 1,000 varieties of medaka, we will introduce the most popular and recommended varieties.

Ryusho Hoshi


Ryusho Hoshi is a modified medaka created in 2021 by a store called Hoshida Medaka. It is a long-finned type of the “Otohime” medaka with a black-rimmed Hikari body. The black rim appears as a net-like pattern on the orange body.

Ryusho Hoshi varies greatly among individuals, but those with a clear black rim and an orange head are extremely beautiful and are called the king of medaka.

For this reason,

Ryusho Hoshi is still traded at high prices even three years after its release. It is also a difficult medaka to purchase as its fixation rate is low and the eggs and fry are delicate, so most breeders do not cultivate it.

However, among the more than 1,000 varieties of medaka, it stands out for its beauty, making it a popular variety that medaka enthusiasts want to keep at least once.

Ryusho Hoshi can cost thousands to tens of thousands of yen for adult fish, but eggs can be purchased for 30 yen each.

Orochi is a particularly black variety of black medaka. Medaka change color based on their background (background response), so black medaka in a white container will appear whitish, but Orochi remains black regardless of the background.

It is reasonably priced and very popular, often seen in medaka shops and tropical fish stores, making it a recommended medaka.

Standard Popular Medaka and Their Varieties

Next, we will introduce recommended varieties of standard popular medaka for beginners.

Yang Guifei

Yang Guifei is the most famous modified medaka. It has a stronger orange color than regular medaka and grows to a particularly beautiful vermilion color when raised outdoors. Yang Guifei medaka are common and often seen in home centers, but there are also varieties like Kotei medaka, which are further improved to be redder, and these are also recommended. Regular Yang Guifei medaka are sold for 100 to 300 yen per fish, making them very affordable.

Among the offspring, there are sometimes regular Yang Guifei or daruma medaka. It is available for a few hundred yen per fish and is recommended for those who want to try keeping a slightly different medaka.

It is available for about 200 yen per fish, making it easy for beginners to purchase and recommended.

Incidentally, most of the modified medaka in circulation, such as Sapphire, are derived from Mikiyuki.

Black Mikiyuki

Black Mikiyuki is a beautiful variety with a black body and external shine. It has more presence than Mikiyuki but is not often seen. Being an old variety, it is very affordable and recommended.

Platinum Seiga

Platinum Seiga is a version of Platinum Mikiyuki with glitter on the back. However, the glitter is only visible from the side, so it is recommended to keep them in a tank. It is a very popular variety with a high fixation rate and is often sold at reasonable prices, making it recommended for beginners.

Green Light

Green Light is a medaka with a rare feature of a green-glowing back. It was believed to be impossible to create green medaka as they lack green pigments. Strictly speaking, it is yellow and blue, but high-grade ones shine green. They are easy to keep and have become more affordable recently, making them recommended.

Black Diamond

Black Diamond is a medaka with glitter patterns on a black body, similar to Orochi medaka. As the name suggests, it is a beautiful medaka with diamond-like glitter within the black color and is very popular.

A large number of them are available, often sold for around 1,000 yen per fish, making them recommended for beginners. However, the fixation rate is not very high, and gray medaka will always appear among the offspring.


Tricolor medaka are medaka with white, black, and red colors. Even with careful selection, it is said that only about 20% of them will have clear tricolor patterns, with perfect individuals appearing once in several hundred to several thousand.

Of course, you can still enjoy them as a beginner without pursuing perfection, and they are often sold at reasonable prices based on their grade, making them easy to obtain. Many enthusiasts fall deeply into breeding tricolor medaka, so if you have a large yard or plenty of time, they are recommended.


Kohaku is a medaka with beautiful white and red contrast. High-grade individuals are as vivid as koi or goldfish, making them very popular and recommended for those who want to purchase medaka with high aesthetic value.

However, like tricolor medaka, Kohaku medaka have a wide variation among individuals, so you need to breed many offspring. It is a deep breed requiring ample breeding space.


Goshiki is a modified medaka with a black body with a touch of red and yellow fins. It is particularly popular among modified medaka for its subdued color and is recommended for beginners. There are various versions, including those with a stronger white color and Type Red with a stronger red color. While not often seen outside of specialty stores, they are also available online.

Tricolor Glitter

Tricolor Glitter is a very beautiful modified medaka with glitter on a tricolor body. It is considered a representative variety of glitter medaka, with high-grade individuals having high aesthetic value and being traded at high prices.

Adding glitter to the already low-fixation tricolor pattern makes selection very difficult, and mastering tricolor glitter medaka definitely requires a lot of space.

Nevertheless, lower-grade ones are sold at affordable prices, making them recommended for beginners.

Recommended Long-Fin Medaka Ranking

Wings of Oblivion


Wings of Oblivion is a long-fin medaka with beautiful gold glitter. It is a new variety created around 2021, which was traded at high prices.

It is often sold for around 1,000 yen per fish, making it recommended for those who want to purchase beautiful medaka.

Ryusho Hoshi


Ryusho Hoshi is a popular medaka with beautiful black rim patterns (black net-like patterns on a red body). The long fins are elegant and highly valued, traded at high prices.
