Description
The Ranchu Goldfish is one of the most iconic fancy goldfish varieties, often called the “King of Goldfish” for its unique beauty and cultural prestige. With its rounded, egg-shaped body, lack of a dorsal fin, and developing head growth (wen), this juvenile Ranchu (4–5 cm) already shows the traits that make it a centerpiece in any aquarium.
Key Features
- Distinctive Shape: Egg-shaped body, smooth arched back, and no dorsal fin.
- Developing Wen: Juvenile head growth that becomes more prominent with age.
- Vibrant Colors: Gold, orange, red, white, or calico variations.
- Peaceful Temperament: Ideal for community tanks with other fancy goldfish.
- Perfect Starter Size: At 4–5 cm, great for hobbyists who enjoy raising fish to adulthood.
Care Guide
- Tank Size: Minimum 20 gallons for one Ranchu (+10 gallons per extra).
- Water Parameters: 18–24°C (65–75°F), pH 6.5–7.5, clean and stable water.
- Diet: High-quality sinking pellets, gel foods, blanched peas, brine shrimp, and bloodworms.

The Ranchu is more than just a goldfish—it’s a living piece of art, admired for centuries for its elegance and grace. Perfect for aquarists who want a prized, beautiful, and culturally significant fish.
