🌍 Origin:

• Orandas are fancy goldfish selectively bred for their unique head growth (wen)

• The Red Oranda is a solid-colored variant with a bright, deep red or orange body

🎨 Appearance:

• Coloration:

  • Entire body and fins are bright solid red, orange-red, or crimson

• Body Shape:

  • Round, egg-shaped body with a short, broad build

• Fins:

  • Flowing double tail (caudal fin), paired pectoral and anal fins

⚧️ Gender Differences:

• Males:

  • May develop breeding tubercles (tiny white bumps) on gills and pectoral fins during breeding season

  • Typically slimmer and more streamlined

• Females:

  • Rounder and fuller body, especially during spawning periods

🟠 Gender identification is difficult until maturity (~1 year or more)

🌡️ Ideal Water Conditions:

✅ Keep the water clean and oxygen-rich, and avoid tropical water temperatures.

🪴 Tank Setup:

• Tank Shape: Wide and long tanks are better than tall ones

• Substrate: Fine gravel or sand

• Decorations:

  • Smooth, rounded decorations to avoid damaging the wen or fins

  • Avoid sharp objects

• Plants: Use hardy plants like Java Fern, Anubias, or plastic plants (ensure no sharp edges)

• Filtration: Moderate to strong filtration with gentle outflow

• Aeration: Highly recommended due to high oxygen demand

👨👩👧👦 Behavior and Compatibility:

• Temperament:

  • Very peaceful, calm, and social

  • Often recognize and interact with their owners

• Swimming Zone: Mid and bottom levels

• Good Tankmates:

  • Other fancy goldfish (Ranchu, Ryukin, Calico Oranda, Fantail)

  • Avoid fast or aggressive fish (e.g., Comet, Koi, Barbs, Cichlids)

🟢 Best kept in small groups or pairs of other fancy goldfish

🍽️ Diet:

• Type: Omnivore

• Ideal Foods:

  • High-quality sinking goldfish pellets or gel foods

  • Blanched veggies: peas (deshelled), spinach, zucchini

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

• Feeding Frequency: 2–3 small feedings daily

❗ Avoid floating food to prevent swim bladder issues. Always soak dry pellets before feeding.

🐣 Breeding:

• Reproduction Type: Egg-scatterer

• Breeding Behavior:

  • Males chase females to stimulate egg laying

  • Eggs are laid on plants or spawning mops

• Post-Spawning Care:

  • Remove adults, as they may eat eggs

  • Eggs hatch in 2–3 days; fry become free-swimming in 4–7 days

• Fry Diet: Infusoria → baby brine shrimp → crushed flakes

⚠️ Common Health Issues:

• Swim Bladder Disorder:

  • Caused by poor diet or water quality

• Wen Infections (fungal or bacterial):

  • Keep the tank clean; avoid injuries to the head cap

• Ich (white spot), fin rot, and constipation are common goldfish problems

✅ Regular water changes (25–40% weekly), high-quality diet, and stable conditions help prevent diseases.

🧠 Fun Facts:

• Red Orandas are often called the “King of Goldfish” due to their royal look and showy appearance

• They are considered lucky symbols in Chinese and Japanese culture

• Their head cap (wen) is unique to each fish, much like a fingerprint

• They can live 15+ years with excellent care
