When it comes to choosing a goldfish, you might think all goldfish are created equal. After all, they’re just orange fish, right? Well, not exactly! There’s a big difference between common goldfish and fancy goldfish, and understanding those differences can help you pick the perfect one for your tank. So, let’s dive in and explore the fascinating world of these two types of goldfish—because trust us, there’s a lot more to these fish than meets the eye!
1. What Are Common Goldfish?
Common goldfish, also known as Carassius auratus, are the classic goldfish you probably think of when you imagine this species. They have been around for centuries, and for good reason—they’re hardy, simple to care for, and tend to live long lives. These are the goldfish that many people start with.
Physical Features:
- Slim Body: Common goldfish are typically sleek and slender. No fancy fins or puffy tails—just simple, elegant, and easy to love.
- Size: They can grow quite large! Common goldfish can reach lengths of up to 12-14 inches in a tank, and sometimes even longer in ponds. So don’t be fooled by that tiny fish you saw at the pet store—it could grow to be a real giant!
- Color: While they’re mostly orange, some common goldfish can also be red, yellow, or even white. But they’re still pretty basic when compared to their fancy counterparts.
Behavior:
- Active Swimmers: Common goldfish are very active swimmers and love to explore their environment. They’re always on the go, so make sure they have plenty of space to roam.
- Social: They’re friendly fish and can live peacefully with other goldfish and non-aggressive species.
2. What Are Fancy Goldfish?
Now, if you want a goldfish with a little more personality (and a lot more flair), fancy goldfish might be the way to go. These goldfish are the divas of the goldfish world. They have all sorts of interesting shapes, colors, and characteristics that make them stand out.
Fancy goldfish have been selectively bred over hundreds of years to have specific traits, and they’re often seen as showpieces because of their unique looks.
Physical Features:
- Unique Body Shapes: Fancy goldfish come in all sorts of funky shapes! From round bodies to egg-shaped forms, they’re definitely the “high-maintenance” cousins of common goldfish.
- Funky Fins and Tails: One of the most striking features of fancy goldfish is their fancy fins and tails. Whether it’s a butterfly tail, ranchu tail, or veil tail, these goldfish can be quite the eye-catchers.
- Size: Fancy goldfish are typically smaller than common goldfish. They usually max out at 6 to 8 inches, which can be a good option if you’re working with a smaller tank.
Behavior:
- Slower Swimmers: Fancy goldfish tend to swim a bit more slowly than their common counterparts, which makes them appear more graceful. However, their fancy fins and body shapes can sometimes make them less agile in the water.
- Gentle and Peaceful: Fancy goldfish are just as friendly as common goldfish. But because they have slower swimming speeds, they might not do well with faster, more aggressive tankmates.
3. Care Requirements: Common Goldfish vs. Fancy Goldfish
While both common and fancy goldfish require similar care, their differences in size and swimming style do influence how you should set up their tank.
Tank Size:
- Common Goldfish: They need larger tanks due to their potential size. A single common goldfish will require at least a 20-gallon tank, and if you plan to have more than one, you’ll need to add another 10 gallons for each additional fish.
- Fancy Goldfish: Fancy goldfish, being smaller, can be kept in a slightly smaller tank, but they still need a minimum of 20 gallons for one fish. Keep in mind that their fancy fins may require them to have a more gentle filtration system, as they might struggle against strong currents.
Water Quality:
- Both types of goldfish are cold-water fish and do not need a heater. However, it’s crucial to keep the water clean and well-oxygenated. Goldfish can produce a lot of waste, so make sure you have a good filtration system to maintain water quality.
Diet:
- Both goldfish love to eat high-quality pellets, but fancy goldfish might need a more carefully tailored diet due to their different body types. Fancy goldfish with rounder bodies (like Ranchus) are more prone to swim bladder issues, so be careful with overfeeding.
4. Goldfish Lifespans: Common vs. Fancy
Goldfish are known for their impressive lifespan, and both common and fancy goldfish can live for 10-20 years (sometimes even longer!). However, common goldfish are generally hardier, so they may live longer and are less likely to get sick compared to fancy goldfish, who are sometimes a bit more sensitive due to their unique body shapes.
5. Choosing the Right Goldfish for You
When deciding between a common goldfish and a fancy goldfish, there are a few things to consider:
- Space: If you have a large tank (and lots of room for your fish to grow), go for a common goldfish. They’re perfect for outdoor ponds or big indoor tanks.
- Aesthetic: If you want something a bit more showy, fancy goldfish are great for adding beauty and personality to your tank. Plus, they’re a bit smaller, making them ideal for medium-sized tanks.
- Time and Effort: Common goldfish are a bit easier to care for due to their sturdier nature. Fancy goldfish, on the other hand, may require more maintenance, especially when it comes to their specialized care and diet.
6. Which Goldfish Is Better for Beginners?
If you’re new to goldfish keeping, you might be wondering which type is easier for beginners: common goldfish or fancy goldfish. Let’s break it down:
- Common Goldfish: These are generally a great choice for beginners because they’re hardy and relatively low-maintenance. As long as you keep their water clean and feed them properly, they’ll do well in most environments. Common goldfish are also more adaptable to slight changes in temperature and water quality, which can be helpful for new fish owners.
- Fancy Goldfish: Fancy goldfish can still be a good choice for beginners, but they may require a bit more attention to their tank conditions and diet. Their unique body shapes (like the round Ranchu or the fancy fins of a Veiltail) can make them more prone to health issues like swim bladder problems or difficulty swimming in strong currents. If you’re up for the challenge and ready to provide the extra care, fancy goldfish can be very rewarding.
In short, common goldfish might be the better option if you’re just starting out. They are less fussy about their environment and more forgiving of mistakes.
7. Fun Facts About Goldfish
Now that we’ve talked about the serious stuff, here are a few fun facts to make you appreciate your goldfish even more:
- Goldfish Can Recognize Their Owners: No, they’re not just mindlessly swimming around. Goldfish can actually recognize their owners’ faces! They’re like the loyal dogs of the fish world. (But they don’t chase you when you come home, unfortunately.)
- Goldfish Don’t Have Stomachs: That’s right—goldfish don’t actually have stomachs! Instead, food moves through their intestines very quickly. So, if you overfeed them, it can lead to swim bladder issues or other health problems. Keep those portions in check, people!
- They Can Live in Ponds: Both common and fancy goldfish can thrive in outdoor ponds (especially common goldfish). Ponds offer plenty of room for them to grow, and they enjoy the natural environment. Just make sure the water quality is good and predators are kept at bay (no herons allowed!).
Final Thoughts: Common Goldfish vs. Fancy Goldfish
Whether you choose the classic, robust common goldfish or the elegant and graceful fancy goldfish, you’re in for a wonderful journey of pet ownership. Both types bring something unique to the table—common goldfish offer simplicity and resilience, while fancy goldfish provide beauty and charm. Choose the one that suits your tank size, time commitment, and personal preferences, and prepare for years of delightful fishkeeping.
Remember, a healthy goldfish is a happy goldfish, so keep the water clean, feed them right, and give them the space they need to flourish. Good luck, and enjoy the magical world of goldfish!

FAQs About Common Goldfish vs. Fancy Goldfish
1. What’s the main difference between common goldfish and fancy goldfish?
Answer: The main difference is in their appearance and body shape. Common goldfish have a slim, sleek body, and are typically orange, while fancy goldfish have rounder bodies, fancy fins, and come in a variety of shapes, colors, and fin types, like the Ranchu, Veiltail, and Oranda.
2. Which goldfish is easier to care for?
Answer: Common goldfish are generally easier to care for, especially for beginners. They are hardier, can tolerate a wider range of water conditions, and don’t have the special care requirements of fancy goldfish, such as being cautious with their swim bladder or unique fin shapes.
3. How big do common goldfish get compared to fancy goldfish?
Answer: Common goldfish can grow much larger, reaching 12-14 inches or more in a tank, while fancy goldfish usually stay smaller, around 6-8 inches on average. Keep this in mind when deciding what size tank to get!
4. Can common and fancy goldfish live together?
Answer: Yes, but it’s important to consider their behavior. Common goldfish are faster swimmers, while fancy goldfish tend to be slower. This could lead to some competition for food or stress for the fancy ones if the common goldfish are too active. If you do mix them, make sure the tank is large enough and has hiding spots.
5. Are fancy goldfish more delicate than common goldfish?
Answer: Yes, fancy goldfish are generally more delicate. Due to their body shape and fins, they can be more prone to certain health issues like swim bladder problems and difficulty swimming in strong currents. Common goldfish are more robust and better suited to a wider range of tank conditions.
6. Do common and fancy goldfish require the same tank conditions?
Answer: Both types are cold-water fish and have similar temperature needs, ranging from 65°F to 72°F (18°C to 22°C). However, fancy goldfish may require slightly calmer water (due to their delicate fins) and more gentle filtration, whereas common goldfish can handle a stronger current.
7. Which goldfish lives longer, common or fancy?
Answer: Both can live for 10-20 years or even longer with proper care. However, common goldfish are typically a bit more resilient, and some studies suggest they might have a slightly longer lifespan compared to fancy goldfish, who can be more prone to illness due to their unique body shapes.
8. Are fancy goldfish more expensive than common goldfish?
Answer: Yes, fancy goldfish can be more expensive, especially the more rare or specialized breeds like Ranchus or Orandas. Their unique appearance and selective breeding contribute to their higher price. Common goldfish are generally more affordable and easier to find.
9. How much space do common and fancy goldfish need?
Answer: Both types need adequate space to swim. A single common goldfish needs at least 20 gallons of water, while fancy goldfish can often be kept in a slightly smaller tank (around 20 gallons for one fish). However, the bigger, the better for both, especially if you have multiple goldfish.
10. Do common and fancy goldfish eat the same food?
Answer: Yes! Both types of goldfish have similar dietary needs. They should be fed a high-quality goldfish pellet diet, with occasional vegetables like peas or spinach. Just be careful not to overfeed them, as goldfish can easily become overweight, especially the round-bodied fancy goldfish.
