Description

The Black Ranchu Goldfish, a variant of the Carassius auratus species, is a captivating and prized ornamental fish known for its charming appearance, distinctive body shape, and elegant swimming style. This fancy goldfish variant is a favorite among aquarists and water garden enthusiasts, prized for its unique features.

Physical Characteristics:

  • Size: Black Ranchu Goldfish typically grow to an adult size of 6 to 8 inches (15 to 20 centimeters) or even larger, depending on environmental conditions and care.
  • Body Shape: Ranchu Goldfish are characterized by their unique body shape, often described as a "dorsal-less" goldfish due to their lack of a dorsal fin. Instead, they have a rounded back, and their body is arched, creating a distinct, egg-shaped appearance.
  • Coloration: The primary color of the Black Ranchu is, as the name suggests, black. However, variations may include a deep, velvety black color with contrasting metallic or matte scales. Some may exhibit hints of red, orange, or yellow on their bodies, particularly on the gill plates and fins.
  • Finnage: Their fins are typically paired with a balanced and graceful appearance, contributing to their overall elegance.

Behavior and Temperament: Black Ranchu Goldfish are known for their gentle and peaceful nature. They are well-suited for community tanks with other compatible fish species. Their slow and graceful swimming style adds a calming presence to aquariums and water gardens.

Habitat and Tank Requirements:

  • Tank Size: Due to their potential size and body shape, Black Ranchu Goldfish require a spacious aquarium or pond. A 20-gallon (75-liter) tank is suitable for a young Ranchu, but they may outgrow it quickly. Ponds with ample space and water volume are often preferred for adult Ranchus.
  • Substrate: Use a soft substrate like sand or smooth gravel to prevent injury to their delicate, protruding underbelly (caudal peduncle).
  • Filtration: Efficient filtration and maintenance of water quality are crucial for Ranchu Goldfish. Ample filtration is required to ensure optimal oxygenation and removal of waste.
  • Decor: Provide a well-decorated environment with live or artificial plants, rocks, and driftwood. Black Ranchus appreciate places to explore and hide. Floating plants can provide shade and refuge.
  • Water Parameters: Ranchu Goldfish thrive in freshwater conditions with a temperature range of 65°F to 75°F (18°C to 24°C), a pH level between 6.5 and 7.5, and moderate water hardness.

Diet: Black Ranchu Goldfish are omnivorous and require a balanced diet. Offer them high-quality pellets, flakes, and granules formulated for goldfish. Supplement their diet with fresh or frozen foods like brine shrimp, daphnia, bloodworms, and vegetable matter such as blanched spinach or peas.
