Different Types Of Goldfish – Your Ultimate Guide To Choosing
Think of a goldfish, and what comes to mind? For many, it’s a lone, orange fish swimming circles in a small glass bowl. But what if I told you that image is one of the biggest myths in the aquarium hobby?
The truth is, the world of goldfish is incredibly vast, vibrant, and full of personality. The sheer variety among the different types of goldfish is astonishing, ranging from sleek, athletic swimmers built for ponds to ornate, slow-moving beauties that look like living art.
Imagine your own thriving aquarium, home to a graceful Fantail with a flowing tail or a charming, bubbly-cheeked Bubble Eye. Choosing the right one is the first step to creating that dream setup, and it’s easier than you think. Don’t worry—we’re here to help you navigate this exciting world.
In this complete different types of goldfish guide, we’ll dive deep into everything you need to know. We’ll explore the main families, introduce you to the most popular varieties, and give you the expert tips you need to help them thrive. Let’s find the perfect goldfish for you!
The Two Main Goldfish Families: Single-Tailed vs. Fancy
Before we meet individual breeds, it’s crucial to understand the two major categories of goldfish. This single distinction will be the most important factor in deciding what kind of aquarium you’ll need and which fish can live together peacefully.
Single-Tailed Goldfish: Hardy and Athletic Swimmers
These are the fish that most closely resemble their wild carp ancestors. They have long, streamlined bodies and a single tail fin, making them fast and agile swimmers. They are incredibly hardy and can grow very large—often over a foot long!
Because of their size and energy levels, single-tailed goldfish are not well-suited for most indoor aquariums. They truly thrive in large outdoor ponds where they have ample room to swim. Common varieties include:
- Common Goldfish: The classic, orange fish often seen at carnivals.
- Comet Goldfish: Similar to the Common but with a long, elegant, deeply forked tail.
- Shubunkin: Known for their beautiful calico patterns (a mix of orange, red, white, blue, and black) and nacreous scales, which give them a pearly shine.
Fancy Goldfish: The Ornate Aquarium Stars
This is where the real visual diversity comes in! Fancy goldfish have been selectively bred for centuries to have unique body shapes, colors, and features. They typically have a rounder, egg-shaped body and a double (or paired) tail fin, which makes them much slower, more clumsy swimmers.
Their slower nature and slightly more delicate constitutions make them perfect for indoor aquariums. However, their unique traits often require specific care. This is the group we’ll focus on for most home aquarium keepers. Exploring this category is key to understanding how to different types of goldfish can be cared for properly.
A Closer Look at the Different Types of Goldfish for Beginners
Ready to meet some of the stars of the show? These fancy varieties are fantastic choices for those just starting their goldfish journey. They are relatively hardy, widely available, and endlessly charming. This section serves as a great starting point in your different types of goldfish care guide.
The Fantail Goldfish
If you’re looking for the quintessential beginner fancy goldfish, the Fantail is it. They have a classic egg-shaped body and a beautiful, flowing split tail that looks like a fan. They are one of the hardiest fancy varieties and are less prone to some of the issues that affect more specialized breeds.
Temperament: Peaceful and social.
Max Size: 6-8 inches.
Pro Tip: Fantails are active for a fancy goldfish, so they appreciate plenty of open swimming space in their tank.
The Ryukin Goldfish
The Ryukin is a showstopper, distinguished by a prominent hump on its back just behind its head. This gives it a unique, triangular body shape. Their tails are often exceptionally long and flowing, making them incredibly graceful in the water.
Temperament: Can be a bit more competitive during feeding time, so make sure everyone gets food.
Max Size: 6-8 inches.
Pro Tip: Their tall body shape makes them slightly more susceptible to swim bladder issues. Feed a high-quality sinking pellet to prevent them from gulping air at the surface.
The Black Moor Goldfish
With their deep, velvety black color and large, protruding telescopic eyes, Black Moors are a favorite for a reason. They bring a dramatic and beautiful contrast to any aquarium. Don’t worry—their black color is usually stable, though some may develop a bronze or orange tint as they age.
Temperament: Gentle, docile, and slow-moving.
Max Size: 6-8 inches.
Important Note: Their telescopic eyes give them very poor eyesight. They should be kept with other slow-moving, poor-sighted fish (like other Moors or Bubble Eyes) and have a tank free of sharp decorations.
The Oranda Goldfish
Orandas are famous for the fleshy, raspberry-like growth on their heads called a “wen” or “crown.” This unique feature, combined with their large bodies and graceful fins, makes them one of the most popular fancy goldfish. They come in many colors, including red-cap, black, blue, and calico.
Temperament: Generally peaceful and friendly.
Max Size: 8-10 inches.
Wen Care: The wen can sometimes overgrow, covering the fish’s eyes or gills. It’s also prone to bacterial infections. Maintaining pristine water quality is the best practice to keep the wen healthy.
Advanced & Unique Goldfish for the Experienced Keeper
Once you’ve mastered the basics, you might feel drawn to some of the more exotic and delicate goldfish. These breeds require specialized care and a very stable environment, making them a rewarding challenge for the dedicated aquarist.
The Bubble Eye Goldfish
This is arguably one of the most unique-looking fish in the world. The Bubble Eye is defined by the large, fluid-filled sacs that develop beneath its eyes. These sacs are extremely delicate and can be punctured easily.
Care Level: Expert. They must be kept in a bare-bottom tank with no sharp objects. Filtration intake sponges are a must. They should only be housed with other Bubble Eyes or Celestial Eyes.
The Celestial Eye Goldfish
Another fascinating breed, the Celestial Eye lacks a dorsal fin and has permanently upturned, telescopic eyes, as if it’s always gazing toward the heavens. Like the Bubble Eye, its vision is severely impaired, and it requires a carefully managed, safe environment.
Care Level: Expert. Their unique eyes make it hard for them to find food, so they need to be kept with other slow-moving fish where there is no competition.
The Ranchu Goldfish
Referred to in Japan as the “King of Goldfish,” the Ranchu is a highly prized variety. They have a broad, curved back and no dorsal fin, giving them a distinct, almost buffalo-like appearance. They are judged on the smoothness of their back curve and the quality of their wen development.
Care Level: Intermediate to Advanced. Their lack of a dorsal fin makes them slightly wobbly swimmers. They require pristine water to prevent infections on their wen and skin.
Your Goldfish Care Guide: Best Practices for All Varieties
Knowing the breeds is only half the battle. The true secret to success is providing the right environment. Following these different types of goldfish best practices will ensure your fish live a long, happy, and healthy life.
Tank Size Matters (A Lot!)
Forget the bowl. It’s the single worst environment for a goldfish. They produce a lot of waste and need ample space to swim and grow.
- For Fancy Goldfish: A 20-gallon tank is the absolute minimum for one. A 30-40 gallon tank is much better.
- Add More Fish: For each additional fancy goldfish, add another 10-15 gallons of water volume.
- For Single-Tailed Goldfish: A 75-gallon tank is a starting point for one young fish, but they will ultimately need a pond of several hundred gallons.
Filtration and Water Quality
Goldfish are notoriously messy eaters and produce a lot of ammonia-rich waste. A powerful filter is not optional—it’s essential. We recommend a hang-on-back or canister filter rated for at least twice the volume of your tank.
Weekly water changes of 25-50% are crucial for removing nitrates and keeping the water clean and stable. This is the #1 thing you can do for your goldfish’s health.
Feeding Your Goldfish a Balanced Diet
A varied diet is key. A high-quality, sinking pellet or gel food should be their staple. This prevents them from gulping air at the surface, which can lead to buoyancy problems.
You can supplement their diet with treats like blanched peas (great for digestion!), daphnia, and brine shrimp. Feed only what they can consume in about one minute, once or twice a day.
Common Problems with Different Types of Goldfish (and How to Solve Them)
Even with the best care, problems can arise. Being able to spot them early is key. Here are some of the most common problems with different types of goldfish and what to do.
Swim Bladder Disease
Symptom: The fish has trouble controlling its buoyancy. It may be floating to the top, sinking to the bottom, or swimming upside down.
Cause: Often caused by overfeeding, constipation, or gulping air while eating floating foods.
Solution: Fast the fish for 2-3 days. Then, feed it a deshelled, blanched pea. If the problem persists, it could be a bacterial infection or genetic issue.
Fin Rot
Symptom: The edges of the fins appear ragged, frayed, or milky.
Cause: Almost always caused by poor water quality, which allows bacteria to attack the fins.
Solution: Immediately perform a large water change (50%) and test your water parameters. Continue with frequent water changes. In severe cases, antibacterial medication may be needed.
Ich (White Spot Disease)
Symptom: The fish looks like it has been sprinkled with tiny grains of salt or sugar.
Cause: A common parasitic infection, often triggered by stress from poor water quality or temperature fluctuations.
Solution: Ich is highly treatable. Slowly raise the aquarium temperature to 82-84°F (28-29°C) to speed up the parasite’s life cycle, and treat the tank with a commercial ich medication according to the directions.
Sustainable and Eco-Friendly Goldfish Keeping
Part of being a great aquarist is being a responsible one. The concept of sustainable different types of goldfish keeping is about making choices that are good for your fish and the planet.
One of the most important eco-friendly different types of goldfish practices is to never, ever release your fish into the wild. Goldfish are an invasive species that can decimate local ecosystems. If you can no longer care for your fish, please rehome it with another hobbyist or a local pet store.
You can also reduce your environmental footprint by choosing energy-efficient heaters and pumps, sourcing your fish from reputable local breeders instead of mass-market farms, and being mindful of water usage during changes.
Frequently Asked Questions About Different Types of Goldfish
How many types of goldfish are there?
There are over 200 recognized varieties of goldfish worldwide! However, only about 20-30 are commonly available in the aquarium trade. This guide covers the most popular and accessible ones for home keepers.
Can different types of goldfish live together?
Yes, but with a very important rule: keep fancy types with other fancy types, and single-tailed types with other single-tailed types. Fast-swimming Comets will outcompete and stress out a slow-moving Oranda for food. For the best harmony, stick to fish with similar body shapes and swimming speeds.
What is the easiest goldfish for a beginner to keep?
For a standard aquarium, the Fantail is the undisputed champion for beginners. It’s hardy, beautiful, and doesn’t have the extreme features that require specialized care. If you have a large pond, a Shubunkin is an excellent and resilient choice.
How long do goldfish live?
This is one of the biggest benefits of different types of goldfish that people miss! They are not short-lived pets. With proper care in a large-enough tank, a fancy goldfish can easily live for 10-15 years or more. Single-tailed varieties in ponds can live for over 20 years!
