Origins and Classification
- Scientific Name: Carassius auratus (Lionhead Oranda variety)
- Family: Cyprinidae (Carps & Goldfish)
- Origin: A selectively bred fancy goldfish originating from China and Japan, developed for its unique head growth and rounded body form.
- Popularity: Highly prized among goldfish keepers for its distinctive “lion-like” wen (head growth), charming face, and graceful swimming. A favorite in both home aquariums and indoor ponds.
🎨 Appearance
- Color: Found in a range of colors including orange, red, white, black, calico, and bi-color combinations.
- Structure:
- Prominent wen (head growth) covering the top and sides of the head, giving a lion-like appearance.
- Rounded, egg-shaped body with a double tail fin.
- Short dorsal fin or sometimes no dorsal fin depending on the exact strain.
- Size: Typically 5–8 inches (12–20 cm); can grow larger in spacious tanks or ponds.
- Lifespan: 10–15 years, sometimes even 20+ years with excellent care.
🏡 Tank Requirements
- Tank Size: Minimum 30 gallons for one Oranda; add 10–15 gallons for each additional fish.
- Water Parameters:
- Temperature: 65–75°F (18–24°C)
- pH: 6.8–7.8
- Hardness: 5–15 dGH
- Filtration: Strong filtration is essential — fancy goldfish produce a lot of waste.
- Substrate: Smooth gravel or sand.
- Habitat Setup:
- Provide open swimming areas — their body shape makes them slow swimmers.
- Add smooth ornaments or plants (no sharp edges to avoid fin/wen injuries).
- Gentle water flow; avoid high currents.
