Quick Overview

• Scientific Name: Carassius auratus
• Common Name: Tancho Ranchu
• Size: 12–18 cm
• Lifespan: 10–15+ years
• Temperament: Peaceful
• Care Level: Moderate

Appearance

Tancho Ranchus are prized for their pure white body and distinct red head spot, which should ideally be perfectly round and centered. The rounded body and flowing tail complement the Ranchu silhouette, while the wen develops with age, giving them a regal appearance.

⚠️ Tank Size Requirements (Very Important)

Fancy goldfish need ample space:

• ✅ Minimum: 60 litres per goldfish
• ⭐ Ideal: 80–100 litres per goldfish
• ❌ Bowls or small tanks are not suitable

👉 Example:

• 2 Tancho Ranchus = minimum 120L (ideally 160–200L)

Adequate tank space is essential for swimming, growth, and water quality.

Tank Requirements

• Temperature: 18–24°C
• pH: 6.5–7.5
• Filtration: Strong (goldfish produce heavy waste)
• Setup:
  • Smooth substrate or bare bottom
  • Minimal décor to avoid fin or wen damage
  • Open swimming space

Diet

Omnivorous:

• Sinking goldfish pellets
• Gel foods for digestive health
• Blanched vegetables (peas, spinach)
• Occasional protein treats

Tank Mates

• Best kept with other slow fancy goldfish
• Avoid:
  • Fast swimmers (common/comet goldfish)
  • Fin-nippers
  • Tropical species

Behavior

• Peaceful and social
• Slow, waddling swimming style
• Do best in groups of similar-bodied fancy goldfish

Special Considerations

• Wen growth requires clean water to prevent infection
• Heavy waste producers → regular maintenance essential
• No dorsal fin → less stability in strong currents
• Buoyancy issues possible if overfed or fed only floating foods

Why Choose a Tancho Ranchu?

The perfect red-on-white head spot combined with the elegant Ranchu body makes the Tancho Ranchu a standout collector’s goldfish. Ideal for hobbyists seeking a classic and regal centerpiece.
