Have you ever peered into an aquarium and seen a fish that looks more like a living jewel than a simple pet? With flowing fins, wobbly heads, and round, charming bodies, fancy goldfish are some of the most captivating creatures in the aquatic hobby. They are a world away from the common goldfish you might have won at a fair.
But with so many unique varieties, it’s easy to feel a bit overwhelmed. You might wonder if these ornate fish are too delicate or difficult to care for. The good news? They aren’t! With the right knowledge, anyone can create a thriving underwater palace for these beauties.
Imagine your own aquarium, a mesmerizing display of color and graceful movement, becoming the peaceful centerpiece of your home. These fish aren’t just decorations; they have surprisingly big personalities and will quickly learn to recognize you as their favorite person (and food source!).
In this complete fancy goldfish types guide, we’ll dive deep into everything you need to know. From choosing the perfect variety for you to setting up their tank and keeping them happy and healthy for years to come, we’ve got you covered. Let’s get started!
What Exactly Makes a Goldfish “Fancy”?
Before we explore the different varieties, let’s clear up a common question. What’s the difference between a “common” goldfish and a “fancy” one? While they are all the same species, Carassius auratus, they’ve been selectively bred over centuries to have very different features.
Think of it like dog breeds—a Chihuahua and a Great Dane are both dogs, but they look and act quite differently. Common goldfish (like Comets and Shubunkins) have long, streamlined bodies and a single tail fin. They are built for speed and can grow very large.
Fancy goldfish, on the other hand, are the showstoppers. They are defined by two key characteristics:
- A double (or paired) tail fin: This gives them a graceful, flowing appearance in the water.
- An egg-shaped or rounded body: This makes them slower, more deliberate swimmers.
These traits make them completely unsuited for ponds and much better suited for the calmer life of a well-maintained aquarium. Their slower nature is a huge part of their charm!
A Deep Dive into the Most Popular Fancy Goldfish Types
Ready to meet the stars of the show? Choosing a fish is the most exciting part! Here’s a look at some of the most beloved fancy goldfish types, complete with tips to help you pick your new aquatic friend.
The Oranda: The Crowned Jewel
Easily one of the most recognizable fancies, the Oranda is famous for its “wen,” a fleshy, raspberry-like growth that covers its head. This “crown” can take years to fully develop and requires a little extra care to keep clean.
Orandas are generally friendly and curious, making them a fantastic choice for enthusiasts who want an interactive pet. They come in a stunning array of colors, including red-cap, black, blue, and calico.
Care Level: Beginner to Intermediate
Pro Tip: Use a soft toothbrush to gently clean the wen if you ever notice debris trapped in its folds, but only if absolutely necessary and with extreme care.
The Ryukin: The Majestic Humpback
The Ryukin is a powerful-looking fish with a distinct high-arched back, creating a “hump” right behind its head. This, combined with its long, flowing tail fins, gives it a truly majestic and dynamic profile.
Ryukins are active and energetic for a fancy goldfish. They are robust eaters and can be a bit competitive during feeding time, so make sure any tank mates are equally vigorous. Their pointed head and vibrant colors make them a standout in any aquarium.
Care Level: Beginner to Intermediate
Pro Tip: Due to their high back, Ryukins can sometimes be prone to buoyancy issues. Feeding high-quality sinking pellets can help prevent this.
The Fantail: The Classic Beginner’s Choice
If you’re just starting your journey, the Fantail is one of the best fancy goldfish types to begin with. They are hardy, adaptable, and lack the more extreme features that require specialized care. Their body is a classic egg shape, and their defining feature is a split, fan-like tail fin.
Fantails are the quintessential fancy goldfish and provide all the charm without the intensive care some other varieties demand. They are a perfect, low-stress entry into the world of fancies.
Care Level: Beginner
Pro Tip: Fantails are great community fish… with other fancy goldfish! Their peaceful nature makes them excellent tank mates for other slow-swimming varieties.
The Telescope Eye: The Bug-Eyed Wonder
As their name suggests, Telescope Eye goldfish have large, protruding eyes. While this gives them a unique and adorable appearance, it also means their vision is quite poor, and their eyes are delicate.
It is crucial that their aquarium has no sharp decorations, as they can easily injure their eyes. They are slow and sometimes clumsy swimmers, so they need a peaceful tank where they won’t be outcompeted for food. The most popular variety is the all-black Black Moor.
Care Level: Intermediate
Pro Tip: When feeding, drop food in the same spot every time. Your Telescope Eye will learn where to go, ensuring it gets enough to eat.
The Ranchu: The “King of Goldfish”
Highly prized in Japan, the Ranchu is often called the “King of Goldfish.” It has a broad, arched back and, most notably, no dorsal fin. This, combined with a well-developed headgrowth similar to an Oranda, gives it a unique, buffalo-like appearance.
Their lack of a stabilizing dorsal fin makes them slightly awkward swimmers. They are a more delicate variety best suited for experienced aquarists who can provide pristine water conditions and a specialized setup.
Care Level: Advanced
Pro Tip: A bare-bottom tank or one with very smooth, fine sand is ideal for Ranchus to prevent them from scraping their bellies as they forage.
The Pearlscale: The Golf Ball with Fins
The Pearlscale is truly one-of-a-kind. Its scales have a raised, dome-like center that looks like tiny pearls have been embedded on its body. They have a very round, compact body, making them look a bit like a swimming golf ball.
These beautiful scales are unfortunately quite delicate and can be permanently damaged if scraped off. They are slow swimmers and need a gentle environment with perfect water quality to thrive.
Care Level: Intermediate to Advanced
Pro Tip: Avoid keeping them with more boisterous fancies like Ryukins, as the Pearlscale can be easily outcompeted for food and stressed by too much activity.
Setting Up the Perfect Home: A Fancy Goldfish Types Care Guide
Now that you’ve met the fish, let’s talk about their home. Understanding how to fancy goldfish types should be cared for starts with the tank. A proper setup is the single most important factor for their long-term health.
Tank Size: Bigger is Always Better
Forget everything you’ve seen about goldfish in small bowls. That is the biggest myth in the fishkeeping world! Fancy goldfish are messy and need a lot of space to thrive.
A good rule of thumb is:
- Start with a 20-gallon (75-liter) tank for your first fancy goldfish.
- Add an additional 10 gallons (40 liters) for each additional fancy goldfish.
This space gives them room to swim, dilutes the waste they produce, and provides a more stable environment. A larger tank is always easier to maintain than a smaller one.
Filtration: The Unsung Hero
Goldfish produce a lot of waste (ammonia), which is toxic to them. A powerful filter is not optional—it’s essential. You need a filter that can process this waste effectively.
Look for a hang-on-back (HOB) or canister filter rated for a tank larger than the one you have. For example, on a 30-gallon tank, use a filter rated for 40 or 50 gallons. This ensures your water stays crystal clear and safe for your fish.
Water Parameters and Maintenance
Don’t worry, you don’t need a chemistry degree! Just keep an eye on a few key things. Before adding any fish, you must “cycle” your tank to establish beneficial bacteria. Once cycled, aim for these parameters:
- Ammonia: 0 ppm (parts per million)
- Nitrite: 0 ppm
- Nitrate: Below 40 ppm (ideally below 20 ppm)
- pH: 7.0 – 8.0
To keep nitrates low, you’ll need to perform a weekly water change of about 25-50%, depending on your stocking level. This is one of the most crucial fancy goldfish types best practices.
Feeding Your Fancies: Best Practices for Health and Vibrancy
One of the great benefits of fancy goldfish types is that they are eager eaters! But their round bodies make them susceptible to digestive issues if not fed correctly.
What to Feed: A Varied Diet is Key
A high-quality, varied diet is essential for vibrant colors and good health. Avoid cheap flakes.
- Staple Diet: A high-quality sinking pellet or gel food formulated for fancy goldfish. Sinking food prevents them from gulping air at the surface, which can cause buoyancy problems.
- Veggies: Offer blanched (softened) vegetables like shelled peas, spinach, or zucchini a few times a week. Peas are excellent for their digestive system!
- Treats: Occasionally offer frozen or live foods like brine shrimp or daphnia as a protein boost.
How to Feed: Preventing Common Problems
Feed your goldfish 2-3 small meals per day rather than one large one. Only give them what they can completely consume in about a minute. It’s also a great idea to pre-soak dry pellets in a bit of tank water for a few minutes before feeding. This allows them to expand before the fish eats them, further reducing the risk of bloating.
Common Problems with Fancy Goldfish Types (And How to Solve Them)
Even with the best care, you might run into an issue. Here are some common problems with fancy goldfish types and how to handle them calmly and effectively.
Swim Bladder Disease
This is when a fish has trouble controlling its buoyancy—it might float to the top, sink to the bottom, or swim upside down. It’s often caused by constipation or gulping air.
Solution: Fast the fish for 2-3 days, then feed it a blanched, shelled pea. This often helps clear its digestive tract.
Fin Rot
If you see frayed, ragged, or milky-looking edges on your fish’s fins, it’s likely fin rot. This is a bacterial infection almost always caused by poor water quality.
Solution: The number one cure is clean water! Perform a large water change immediately and continue with frequent changes. An aquarium salt bath can also help.
Ich (White Spot Disease)
This is a common parasitic infection that looks like tiny grains of salt sprinkled over your fish’s body and fins.
Solution: Slowly raise your aquarium’s temperature to around 82-86°F (28-30°C) for a week or two, as this speeds up the parasite’s life cycle. You can also treat the tank with a commercial ich medication.
Sustainable and Eco-Friendly Fancy Goldfish Keeping
Being a responsible aquarist goes beyond just your tank. Embracing sustainable fancy goldfish types practices shows a deeper commitment to the hobby and the environment.
Whenever possible, try to source your fish from reputable local breeders instead of large chain stores. These breeders often provide healthier, better-cared-for fish and reduce the stress and carbon footprint associated with long-distance shipping.
Most importantly, never release your goldfish into the wild. They can become a highly invasive species that disrupts local ecosystems. If you can no longer care for a fish, reach out to a local fish club or store to rehome it responsibly.
Even small eco-friendly fancy goldfish types habits, like using the nutrient-rich water from your water changes to fertilize houseplants, can make a difference!
Frequently Asked Questions About Fancy Goldfish Types
Can I keep fancy goldfish in a bowl?
Absolutely not. This is a harmful myth. Fancy goldfish need a minimum of a 20-gallon tank with strong filtration to live a healthy, long life. Bowls are unfiltered, too small, and do not provide enough oxygen or stable water parameters.
How long do fancy goldfish live?
With proper care, a fancy goldfish can live for 10-15 years or even longer! This is a long-term commitment, so be prepared to provide a loving home for many years.
What are the best tank mates for fancy goldfish?
The best tank mates are other fancy goldfish of a similar size and swimming ability. Do not mix them with fast, single-tailed common goldfish, as they will outcompete the fancies for food. Avoid any small fish that could be eaten or aggressive fish that might nip their delicate fins.
Why is my fancy goldfish swimming upside down?
This is a classic sign of a swim bladder issue, a very common problem in round-bodied fish. It’s not usually a disease but a symptom of a digestive problem. Try fasting the fish and then feeding it shelled peas, as detailed in the “Common Problems” section above.
Are fancy goldfish hard to care for?
They are not necessarily “hard,” but they do have specific needs that differ from other tropical fish. They require a large tank, excellent filtration, and regular maintenance. As long as you are committed to meeting these needs, you will find them to be incredibly rewarding and delightful pets.
