Carassius auratus (Oranda variety)

🌍 Origin / History:

  • Originated from China and Japan, bred from Fantail Goldfish

  • Fins:

    • Long, flowing, double caudal fin (tail)

  • Head Growth (Wen):

    • Prominent on the crown of the head; begins developing around 3–4 months and becomes fuller with age

📏 Size:

  • Average Size: 6–8 inches (15–20 cm)

  • Maximum Size: Up to 10–12 inches with optimal care

  • Wen Size: Grows gradually and may cover the whole head if not trimmed


⚧️ Gender Differences:

    • Rounder body, especially when gravid with eggs

Temperature 18°C – 24°C (65°F – 75°F)
pH Level 6.5 – 7.5
Water Hardness 5 – 15 dGH
Tank Size Minimum 20 gallons per fish

🧊 Red Cap Orandas prefer cooler water and are not compatible with tropical fish.


🪴 Tank Setup:

  • Tank Shape: Long tanks preferred for swimming space and oxygen exchange

  • Substrate: Smooth gravel or sand

  • Decor:

    • Use smooth-edged decorations to protect the delicate wen

    • Add plants like Anubias, Java Fern, or plastic plants (avoid sharp ones)

  • Lighting: Moderate lighting to enhance their red cap color

  • Filtration: Moderate to strong, with gentle outflow

  • Aeration: Essential, as goldfish require oxygen-rich water


👨👩👧👦 Behavior and Compatibility:

  • Temperament:

    • Very peaceful, slow-swimming, and social

  • Swimming Zone: Middle and bottom levels

  • Best Tankmates:

    • Other fancy goldfish (Ranchu, Ryukin, Fantail, Telescope Eye)

    • Avoid fast-swimming goldfish (like Common or Comet), and tropical or aggressive fish

  • Group Size: Happy alone or in a group of similar-sized fancy goldfish


🍽️ Diet:

  • Type: Omnivorous

  • Recommended Foods:

    • High-quality sinking goldfish pellets

    • Blanched vegetables: spinach, lettuce, zucchini, shelled peas (great for digestion)

    • Protein: bloodworms, brine shrimp, daphnia (live or frozen)

  • Feeding Frequency: 2–3 times per day in small portions

🟠 Avoid floating foods to prevent swim bladder issues.


🐣 Breeding:

  • Spawning Type: Egg-scatterer

  • Spawning Behavior:

    • Males chase females around the tank

    • Eggs are laid on plants or tank surfaces

  • Breeding Conditions:

    • Increase water temperature gradually

    • Use spawning mops or fine-leaved plants

  • Fry Care:

    • Remove adults post-spawning to avoid egg predation

    • Feed fry infusoria, then baby brine shrimp


⚠️ Common Health Issues:

  • Wen Infections:

    • Can trap debris and lead to fungal or bacterial infections

    • Keep water clean and inspect wen regularly

  • Swim Bladder Disease:

    • Caused by overfeeding or poor diet

  • Ich (white spot) and Fin rot: Common in dirty or cold water

  • Constipation: Prevent with fiber-rich vegetables

✅ Perform weekly water changes (25–40%) and avoid sudden temperature shifts.


🧠 Interesting Facts:

  • The wen does not affect their vision unless it overgrows (some rare cases may require surgical trimming)

  • Considered a symbol of good luck and prosperity in many Asian cultures

  • Highly intelligent and interactive – they may even beg for food!
