Ranchu

The Ranchu is a hooded variety of goldfish that originated in Japan. It is considered by many to be the "king of goldfish" and is highly prized by enthusiasts for its distinctive appearance. Unlike most goldfish, Ranchu are viewed from above (top view) rather than from the side.

Characteristics:

• Body: Ranchu are characterized by their arched back and short, rounded body shape. They lack a dorsal fin, which contributes to their distinctive top view appearance. The body should be smooth and free from deformities.

• Headgrowth (Hood): The prominent headgrowth, also known as the "wen" or "hood," is a defining feature of the Ranchu. It should be well-developed, symmetrical, and cover the head in a uniform manner, though not obstruct the fish's vision or gill function. The quality and shape of the headgrowth is a major factor in determining the value of a Ranchu.

• Tail: The tail is typically short and broad, with a characteristic downward curve. The caudal fin should be flexible and allow for smooth swimming.

• Color: Ranchu come in a variety of colors, including red, white, red and white (sarasa), calico, black, and chocolate.

• Swim: The Ranchu's swimming style is also important. It should have a stable, graceful movement and maintain good balance.

Breeding and Care:

Ranchu are relatively difficult to breed and raise successfully. They require specific water parameters, a balanced diet, and ample space. The development of the headgrowth takes time, and careful culling is necessary to select the best specimens for future breeding.

Grading and Judging:

Ranchu are judged based on a variety of criteria, including body shape, headgrowth, tail shape and movement, color, and overall balance. Competitions are held to evaluate and showcase the best examples of the breed.
