Fancy Goldfish
Fancy Goldfish have a rich history that dates back over a thousand years. They originated in ancient China, where selective breeding of wild carp (Carassius auratus) began during the Tang Dynasty. Over time, the breeding of Goldfish spread to Japan and eventually to Europe and North America. Today’s Fancy Goldfish are a result of generations of careful selection for unique traits such as double tails, round bodies, and elaborate head growths. These fish are now a staple in aquariums worldwide due to their graceful appearance and calm temperament.
Popular Fancy Goldfish Species
Our collection includes some of the most beloved types of Fancy Goldfish, each with its own charm and visual appeal:
- Ranchu Goldfish: Known as the "king of goldfish" in Japan, ranchus have egg-shaped bodies, no dorsal fin, and impressive head growth (wen).
- Telescope Goldfish: Famous for their protruding, globe-like eyes and flowing fins. They come in black, red, calico, and panda variations.
- Ryukin Goldfish: Easily recognized by their humped back, pointed fins, and vibrant colors. A hardy and active variety perfect for larger tanks.
Fancy Goldfish Care Requirements
Fancy Goldfish are beginner-friendly but require some specific care due to their body shape and waste output:
- Tank Size: Minimum 20 gallons for one fish; +10 gallons per additional fish
- Water Temperature: 65–75°F (18–24°C); they do not need a heater unless the room temperatures drop too low
- pH Range: 6.5–7.5
- Filtration: Strong and reliable; canister filters or sponge filters recommended due to high bioload
- Substrate & Decor: Smooth substrate and decorations to avoid fin and eye injuries
- Diet: Feed high-quality goldfish pellets, supplemented with blanched vegetables and occasional treats like bloodworms or brine shrimp
Regular weekly water changes and tank maintenance are key to preventing swim bladder issues and keeping your Fancy Gold Fish healthy and happy.

Fancy Goldfish Frequently Asked Questions (FAQs)
Are Fancy Goldfish hard to keep?
Fancy Goldfish are not hard to keep, but they do require more care than common goldfish due to their unique body shapes and delicate fins. They are hardy and beginner-friendly, but because they produce more waste and are prone to swim bladder issues, they need a spacious, well-filtered Goldfish tank with stable water quality. Regular water changes, a varied diet, and a peaceful environment help ensure long-term health and vibrant coloration.
What is the biggest size of a Fancy Goldfish?
Most Fancy Goldfish varieties grow to about 5 to 8 inches (12 to 20 cm) in length when fully matured. Some larger types, like Ryukin or Oranda, can reach up to 10 inches in optimal conditions. Their size depends on genetics, diet, tank size, and water quality. Providing ample space and proper nutrition is key to helping your fancy goldfish reach its full potential.
How many Fancy Goldfish should I keep per gallon?
The general rule is one Fancy Goldfish per 20 gallons for the first fish, with an additional 10 gallons for each additional Goldfish. Unlike tropical fish, Fancy Goldfish are large-bodied and messy, requiring more space and stronger filtration. Overcrowding a Goldfish tank can lead to poor water quality and health issues, so always prioritize tank size and maintenance when planning your goldfish setup.
