Key Features

• Current Size: Approximately 5–7 cm
• Adult Size: Grows up to 12–15 cm in length.
• Tank Size: Minimum 80 liters per fish; larger tanks are ideal for groups.
• Temperature Range: 18–24°C
• pH Range: 6.5–8.0 (prefers neutral water).
• Diet: Omnivore; thrives on a varied diet.
• Lifespan: 10–15 years with proper care.

Appearance

• Coloration: A stunning mix of red, orange, black, blue, and white with a metallic or pearlescent sheen.
• Body Shape: Rounded, egg-like body with no dorsal fin, giving it a smooth and flowing profile.
• Fins: Short and delicate fins that enhance its elegant swimming style.

Behavior

• Calm, slow-moving, and non-aggressive.
• Peaceful temperament, making it an excellent choice for community tanks with other fancy goldfish.

Tank Setup

• Substrate: Smooth sand or fine gravel to prevent injuries.
• Decorations: Include soft plants and rounded ornaments to minimize fin or scale damage. Avoid sharp edges.
• Filtration: Provide efficient filtration with gentle water flow, as Ranchus are not strong swimmers.
• Water Conditions:
  • Keep water clean with regular changes to maintain their health and vibrant colors.
  • Monitor ammonia and nitrate levels closely.

Feeding

• Diet: A well-balanced diet is crucial for growth and color enhancement:
  • High-quality goldfish pellets or flakes as a staple.
  • Supplement with live or frozen foods such as brine shrimp, bloodworms, and daphnia.
  • Include vegetable-based foods like blanched spinach, peas, or zucchini.

Tankmates

• Best kept with other fancy goldfish varieties like Orandas, Lionheads, or Pearlscales.
• Avoid housing with fast or aggressive fish that might outcompete them for food or nip their fins.

Breeding

• Relatively straightforward but requires a separate breeding tank.
• Males will chase females during spawning, and eggs are scattered on plants or breeding mops.
• Remove parents after spawning to protect the eggs.
• Feed fry with infusoria or finely crushed food.

Special Considerations

• Ranchus are sensitive to poor water quality, so regular maintenance is essential.
• Their lack of a dorsal fin and compact body make them prone to swim bladder issues; avoid overfeeding.
• Ensure a spacious tank with plenty of swimming room to accommodate their active but gentle nature.

Keeping Goldfish FAQ

Water changes?
About 20% weekly. Don't clean the tank otherwise, other than optionally scraping the walls or vacuuming the substrate every so often.

Tank size?
At least 4-6x the length of the fish is ideal, but the bigger the better. Eventually, these should end up in a pond but not everyone has that option.

Feeding?
Once per day is enough, any standard fish food. Note, that they will eat algae and some plants as well. Duckweed is a great snack to keep them healthy as well. 

Tank mates?
Don't keep them with shrimp! Anything they can fit in their mouth they will have a go at, but otherwise won't usually be too aggressive to other fish.
