What Are Fancy Goldfish?
Fancy Goldfish are selectively bred varieties of the common goldfish, distinguished by their rounded bodies, double tail fins, and extravagant features like head growths (wen), bubble eyes, and telescope eyes. They were first developed in China and later refined in Japan and Europe over centuries of selective breeding.
These fancy fish are not as hardy as their wild ancestors and require more care, particularly in terms of water quality and tank conditions. Most Fancy Goldfish types are slower swimmers and more prone to buoyancy issues due to their body shape, so choosing the right environment is crucial.
Popular Species of Fancy Goldfish
Ranchu Goldfish
Known as the "king of goldfish" in Japan, the Ranchu Goldfish has a rounded back, deep belly, and no dorsal fin, giving it a distinct silhouette. They also develop a bumpy head growth (wen) that becomes more pronounced with age.
- Lifespan: 8–15 years
- Size: 5–8 inches
- Special Needs: Soft substrate, low current, peaceful tank mates
Ryukin Goldfish
With a hump behind its head and a pointed dorsal area, the Ryukin Goldfish stands out with a powerful, deep-bodied look. It’s more active than other fancy types and comes in various colors like red, calico, and white.
- Lifespan: 10–15 years
- Size: 6–10 inches
- Behavior: Slightly more aggressive, best kept with similar-sized goldfish
Telescope Goldfish
Recognizable by their protruding eyes and flowing fins, Telescope Goldfish are highly sensitive and require gentle care. Their eyesight is poor, making feeding time a bit competitive if faster tank mates are present.
- Lifespan: 6–10 years
- Size: 6–8 inches
- Best For: Quiet, slow-paced tanks with minimal obstacles
Set Up An Ideal Fancy Goldfish Tank
Tank Size
Fancy Goldfish may look small in the pet store, but they grow significantly. The general rule is 20 gallons for the first fish and an additional 10–15 gallons for each additional goldfish. Overstocking can lead to poor water quality and health problems.
Water Parameters
Goldfish produce a lot of waste, so maintaining water parameters is critical. Weekly water changes of 25–50% are recommended.
- pH: 6.5 to 7.5
- Ammonia/Nitrite: 0 ppm
- Nitrate: Below 40 ppm
- Water Hardness: Moderate (5–15 dGH)
Temperature Requirements
Unlike tropical fish, Fancy Goldfish prefer cooler water. However, extreme fluctuations can cause stress.
- Ideal Temperature: 65°F–75°F
- Avoid: Temperatures below 60°F or above 80°F
Filter
A high-quality filter is essential due to the goldfish’s high bioload. Use a canister filter or hang-on-back filter with mechanical, biological, and chemical filtration. Adding an air stone helps oxygenate the water.
Substrate
Fancy Goldfish love to dig. A soft sand or smooth gravel substrate prevents injury and allows them to exhibit natural foraging behavior.
What Do Fancy Goldfish Eat?
Fancy Goldfish diet should be well-balanced and varied to prevent digestive issues like swim bladder disease.
- Staple Diet: High-quality sinking goldfish pellets
- Supplement With: Blanched vegetables (spinach, zucchini, peas), protein-rich treats (brine shrimp, bloodworms), and gel food for Fancy Goldfish
Feeding Tips:
- Feed 2–3 times per day
- Only provide what they can eat in 2 minutes
- Use sinking food to reduce air swallowing
How Do Fancy Goldfish Breed?
Fancy Goldfish are egg layers and typically breed in the spring or after temperature changes in controlled environments.
- Breeding Behavior: Males chase females, nudging their sides
- Spawning Environment: Use a spawning mop or aquatic plants
- Egg Care: Adults eat eggs, so separate them after spawning
- Incubation: Eggs hatch in 4–7 days, depending on temperature
Breeding requires dedication, but the process can be rewarding and exciting for committed aquarists.
