Top 10 Goldfish Varieties 2027

How We Ranked

• Hardiness — how well the variety tolerates temperature swings, nitrate spikes, and beginner cycling errors.
• Adult size and footprint — single-tailed varieties reach 10-12 inches and need ponds, while fancies stay under 8 inches and fit large tanks.
• Temperament and compatibility — fast single-tails outcompete slow fancies, so mixing matters for feeding and stress.
• Care difficulty — round-bodied fancies face swim-bladder and buoyancy issues that long-bodied fish never deal with.
• Availability and price — common pond types cost a few dollars, while quality show-grade fancies command premiums.

1. Common Goldfish 🏆 BEST OVERALL

The Common Goldfish (Carassius auratus) is the original domesticated form and the toughest variety on this list. It carries a single tail, a streamlined torpedo body, and a metallic orange, red, or yellow finish. Adults routinely reach 10-12 inches and can push past a foot in a mature pond, which is exactly why this fish belongs outdoors or in a stock tank rather than a 20-gallon. It tolerates a remarkable 40-75°F range and shrugs off the nitrate creep that kills more delicate fancies.

For temperament, the common is active, fast, and a relentless eater, so it pairs best with other single-tailed goldfish at similar speed. Keep water at pH 6.5-8.5 with GH around 8-12, and provide at least 10 gallons per adult fish plus aggressive mechanical and biological filtration. This is the variety that survives a child's first aquarium and still lives 15-20 years when given pond space.

• Price / Cost: ~$3-6 each
• Pros: Extremely hardy, cold-tolerant, long-lived, cheap and widely available.
• Cons: Grows very large, needs a pond or 75-gallon-plus, far too big for desktop tanks.

Verdict: The honest gold standard for anyone who can give it real space.

2. Comet Goldfish 💎 BEST VALUE

The Comet Goldfish is an American-bred single-tail prized for its long, deeply forked tail and slim, fast body. It is functionally as hardy as the common but trades bulk for speed and a flowing caudal fin, making it the classic pond and feeder-store fish. Adults reach 8-12 inches, slightly leaner than a common, and the variety includes the popular red-and-white Sarasa Comet color form.

Comets thrive in the same 40-75°F cold-water window and handle wide pH 6.0-8.0 swings without complaint. They are dazzlingly quick swimmers, so they should never share a tank with slow telescope-eye or bubble-eye fancies that cannot compete at feeding time. Give each comet roughly 10 gallons of mature volume and strong flow; they relish current. At under $5 for a healthy juvenile, no variety delivers more durability per dollar.

• Price / Cost: ~$2-5 each
• Pros: Dirt cheap, very hardy, fast and graceful, great pond fish.
• Cons: Outcompetes fancies, needs length to swim, gets large.

Verdict: The most fish for the least money in cold water.

3. Shubunkin Goldfish

The Shubunkin is a single-tailed goldfish famous for its calico coloration — a mottled blue, black, orange, and white pattern overlaid on a translucent, scaleless "nacreous" body. The prized blue base is rare and valuable in show circles. There are London (rounded fins), Bristol (broad heart-shaped tail), and American (long-finned) strains, all sharing comet-like vigor.

Adults reach 9-12 inches, so shubunkins are pond and large-tank fish, not desktop pets. They tolerate 45-75°F and the usual pH 6.5-8.0 range with ease. Because they are fast single-tails, house them only with comets and commons. The calico pattern intensifies in natural sunlight, so ponds bring out their best color. They are an excellent bridge fish for keepers who want pond-grade hardiness with show-grade looks.

• Price / Cost: ~$4-10 each
• Pros: Stunning calico color, hardy, sunlight deepens the blue tones.
• Cons: Large adult size, fast eater, true blue specimens cost more.

Verdict: The hardy pond fish that looks like a fancy.

4. Fantail Goldfish

The Fantail is the entry-level fancy goldfish and the smartest first step into the egg-bodied varieties. It has a rounded, double-tailed body with a split caudal fin held in a graceful fan, but it lacks the extreme features — no telescope eyes, no head growth, no upturned vision — that make other fancies fragile. That restraint makes it the hardiest fancy available.

Adults reach 6-8 inches and do well in a 65-75°F range, slightly warmer than single-tails prefer. Give a pair at least 20-30 gallons with gentle-to-moderate flow, since their double tails make them slower swimmers. Watch for swim-bladder issues common to round-bodied fish; feed pre-soaked, sinking pellets and the occasional blanched pea. Fantails coexist peacefully with other slow fancies like orandas and ryukins.

• Price / Cost: ~$5-12 each
• Pros: Hardiest of the fancies, manageable size, beginner-friendly double-tail.
• Cons: Prone to buoyancy issues, slower than single-tails, warmer preference.

Verdict: The best on-ramp into fancy goldfish keeping.

5. Ryukin Goldfish

The Ryukin is a Japanese fancy defined by its dramatic, pronounced shoulder hump behind the head and a deep, rounded body. It comes in short-tail and long-tail varieties and in red, white, calico, and tricolor patterns. Among the round-bodied fancies it is one of the sturdiest and most active, often holding its own against slower tankmates.

Ryukins reach 6-8 inches in body length, sometimes more with the tail, and prefer 65-75°F. Their deep body needs water height, so a 30-gallon minimum for one and 10 gallons per additional fish keeps water stable. Strong biological filtration is essential because their compact gut and heavy bodies produce a lot of waste. Feed a varied diet of sinking pellets, gel food, and vegetables to support that bulky frame and reduce floaty episodes.

• Price / Cost: ~$8-25 each
• Pros: Bold body shape, relatively robust fancy, vivid color options.
• Cons: Heavy waste load, can be pushy with frailer fancies, swim-bladder prone.

Verdict: A characterful fancy with above-average vigor.

6. Oranda Goldfish

The Oranda is the celebrity fancy, instantly recognized by the raspberry-like wen — a fleshy hood that grows over its head and cheeks. The red-capped white form, the Red Cap Oranda, is among the most popular goldfish on earth. It carries a round egg body, double tail, and slow, regal swimming style.

Orandas reach 6-9 inches and like 65-78°F, tolerating the warmer end better than single-tails. Provide a 30-gallon base plus 10-15 gallons per added fish and pristine water, because the wen can trap debris and develop bacterial infections if nitrates climb. Keep flow gentle so they are not buffeted, and avoid sharp decor that snags the hood. The wen can grow large enough to crowd the eyes, so watch vision and feeding. A healthy oranda is a stunning centerpiece.

• Price / Cost: ~$10-40 each
• Pros: Iconic head growth, beautiful, peaceful, many color forms.
• Cons: Wen needs spotless water, vision can suffer, sensitive to poor conditions.

Verdict: The classic show fancy for keepers who maintain clean water.

7. Black Moor Goldfish

The Black Moor is a telescope-eyed fancy cloaked in deep velvet black, with protruding dome eyes mounted on stalks. The eyes give it poor vision, so it is a slow, deliberate fish that relies on smell to find food. It is one of the more forgiving telescope varieties, which is why it earns a mid-list spot rather than a fragile-fancy ranking.

Black Moors reach 6-8 inches and do best at 65-75°F. Because of their weak eyesight, keep them with equally slow fancies — never fast comets that strip the food first — and remove any sharp gravel, rough rocks, or hard plastic plants that could scratch the exposed eyes. A 20-30 gallon tank with smooth substrate and gentle flow suits a pair. Their black can fade toward bronze or orange as they age, especially in warm water, which is normal.

• Price / Cost: ~$6-18 each
• Pros: Striking velvet color, peaceful, more robust than other telescope eyes.
• Cons: Poor vision, vulnerable eyes, color can fade with age.

Verdict: The approachable telescope-eye for a gentle community.

8. Pearlscale Goldfish

The Pearlscale, or Chinshurin, is the golf-ball goldfish — a spherical fancy whose scales each carry a raised, dome-shaped calcium deposit that gives a beaded, pearly texture. The crown pearlscale adds a fleshy head growth on top. Its near-round body is charming but mechanically demanding, because that shape crowds the internal organs and makes buoyancy control tricky.

Pearlscales stay smaller at 5-8 inches and prefer a warm, stable 68-78°F. Sudden temperature drops or chilled water can crack the pearl scales, which do not regrow normally, so heater-stabilized tanks suit them. A 20-gallon minimum with very gentle flow and easily digested food keeps them upright. Soak pellets and offer daily greens to fight the floating and sinking spells these round bodies are prone to. They are best for intermediate keepers who can hold steady conditions.

• Price / Cost: ~$8-25 each
• Pros: Unique beaded texture, compact size, eye-catching novelty.
• Cons: Fragile pearl scales, buoyancy issues, needs warm stable water.

Verdict: A specialist's fancy that rewards careful warmth and clean water.

9. Telescope Goldfish

The Telescope (Demekin) goldfish takes the dome-eye trait of the Black Moor and offers it in a full color range — red, calico, panda, and chocolate among them. The protruding eyes develop a few weeks after hatching and leave the fish nearly blind, fully dependent on scent. It is essentially a Black Moor in different clothing, ranked just below it because non-black forms tend to be a touch more delicate.

Telescopes reach 6-8 inches and want 65-75°F. Tank rules mirror the moor: smooth substrate, no sharp decor, gentle flow, and only slow tankmates. The popular Panda Telescope with its black-and-white markings is gorgeous but the contrasting color can shift over time. Provide a 20-30 gallon tank and target-feed to make sure these poor-sighted fish actually find their meals before quicker fish do.

• Price / Cost: ~$8-30 each
• Pros: Wide color palette, peaceful, distinctive eyes.
• Cons: Near-blind, fragile eyes, needs slow tankmates and soft decor.

Verdict: A colorful telescope-eye for patient, gentle setups.

10. Bubble Eye Goldfish

The Bubble Eye is the most extreme and most fragile variety on this list, included because it is a genuine, recognized goldfish and a fascinating one — just not a beginner fish. It has no dorsal fin and carries two large, fluid-filled sacs beneath each eye that wobble as it swims and force the eyes to point upward. Those sacs can rupture on any sharp object, and while they sometimes heal, they may not return to symmetry.

Bubble Eyes stay around 5-7 inches and like 65-75°F. They demand a bare or very smooth tank with zero sharp decor, no aggressive intake strainers, and the calmest possible flow, since they are weak, clumsy swimmers. House them only with their own kind or other slow, sightless fancies; never with single-tails. A 20-gallon species tank suits a pair. This is a fish for the experienced fancy keeper who can build a hazard-free environment.

• Price / Cost: ~$10-30 each
• Pros: Truly unique appearance, gentle, a conversation piece.
• Cons: Extremely fragile sacs, poor swimmer, demanding hazard-free tank.

Verdict: The expert's novelty, not a first goldfish.

How to Choose

What to Look For

Match the variety to your space first. Single-tailed fish — common, comet, shubunkin — grow 10-12 inches and need a pond or a tank of 75 gallons or more, so never buy them for a desktop bowl. Round-bodied fancies stay smaller but still want 20-30 gallons for the first fish plus 10 gallons per added fish, because goldfish are heavy ammonia producers that overwhelm undersized filters. Run mechanical and biological filtration rated for at least double your tank volume, and plan weekly water changes of 30-50 percent. Never mix fast single-tails with slow telescope-eye or bubble-eye fancies; the quick fish strip every meal before the sightless ones find it. Quarantine new fish for two to four weeks to screen for ich and flukes, keep decor smooth for protruding-eye varieties, and feed pre-soaked sinking food to round bodies to head off swim-bladder trouble.

FAQ

What size tank do I need for a Common Goldfish? A single Common Goldfish needs at least a 75-gallon tank or a pond, as it can reach 10–12 inches. Smaller tanks stunt growth and shorten lifespan.

Are fancy goldfish harder to keep than single-tail varieties? Yes, fancy goldfish like Orandas and Ryukins are less hardy due to their rounder bodies and slower swimming, requiring stable water conditions and careful feeding.

Can I keep goldfish in a bowl or small aquarium? No, goldfish produce heavy waste and need large tanks with strong filtration—bowls cause ammonia buildup and early death.

How often should I change the water for goldfish? Weekly water changes of 25–50% are typical, but the exact frequency depends on tank size, filtration, and fish load—test ammonia and nitrates to adjust.

Do goldfish need a heater? Most goldfish thrive in cold water (40–75°F) and don't require a heater, but stable temperatures prevent stress—avoid sudden swings.

What is the best diet for goldfish? A varied diet of sinking pellets, fresh vegetables, and occasional live foods supports health; overfeeding is a common mistake that fouls water.

Bottom Line

The Common Goldfish is the overall winner for its unmatched hardiness and 15-20 year lifespan, provided you give it pond or large-tank space. The Comet Goldfish is the value champion at under $5, delivering the same durability in a faster, slimmer body. From there, pick by skill: a Fantail or Oranda for indoor fancy keepers, and the delicate Bubble Eye only once you can build a truly hazard-free tank.
