Goldfish are probably the world’s most popular freshwater aquarium fish, and with over 200 recognized types of goldfish, there’s a breed for everyone!

Read along as we introduce 35 awesome goldfish breeds that you can keep in your aquarium!

Key Takeaways

  • Goldfish have a rich history, and they come in a wide range of shapes, sizes, and colors
  • Slim-bodied goldfish are cheaper, hardier, and easier to care for than fancy goldfish
  • Fancy goldfish require more care than slim-bodied breeds
  • Some goldfish breeds can grow to over 12 inches, so they need plenty of space and high-quality filtration to stay healthy

Species Background

The goldfish (Carassius auratus) is a freshwater fish from China that is kept in aquariums and ponds all over the globe. These fish prefer cool, slow-flowing, or still water in nature, and the largest individuals can grow to over 16 inches long and weigh over 5 pounds if they have enough space.

Aquarists have long prized the goldfish for its grace and beauty, and they first started breeding these fish over a thousand years ago! Today they are as popular as ever, and selective breeding has created an awesome variety of different breeds.

Slim-bodied Vs Fancy Types – What’s The Difference?

The two major goldfish breed categories are slim-bodied and fancy breeds – read on to learn more about these goldfish types.

Slim-bodied Varieties

Slim-bodied goldfish like common, feeder, and comet goldfish have been bred into many colors, although their streamlined, torpedo-shape is just as nature intended. These are the most common and most affordable breeds of goldfish and the type most people are familiar with.

Slim-bodied goldfish are hardy and very easy to care for without any advanced care requirements. That means they make excellent beginner fish, as long as you can provide the following basic requirements:

Let’s take a look at some of the pros and cons of the slim-bodied breeds

Pros:

  • Slim-bodied goldfish come in a range of beautiful colors and fin types
  • Slim-bodied goldfish are very affordable. You can usually find feeder goldfish for less than a dollar each!
  • These fish are super easy to find at just about any pet store
  • Common goldfish are very hardy, which makes them great for an outdoor pond

Cons:

  • Slim-bodied goldfish get surprisingly large and their active swimming habits make them unsuitable for small aquariums
  • Goldfish are natural omnivores, and these faster swimming varieties can catch and eat small tank mates

Fancy breeds

Fancy goldfish are the product of centuries of careful selective breeding, and the results are adorable! These fish may have strange, bulging bubble eyes, humped backs without dorsal fins, or even bulbous growths on their foreheads and gill covers.

However, such extreme variation has come at a cost, and these eye-catching features make them much more sensitive, which means they require more specialized care. They are more expensive too, so these goldfish breeds are better suited to more experienced fish keepers.

Let’s take a look at a few more pros and cons of keeping fancy goldfish.

Pros:

  • Fancy goldfish have been bred into some truly adorable shapes, and their clumsy movements make them very entertaining
  • Fancy goldfish can be fascinating to breed for more advanced hobbyists
  • Fancy goldfish are relatively small goldfish breeds, although most types can reach 6 to 8 inches

Cons:

  • Fancy goldfish can be pretty expensive, particularly when you start looking at rare varieties
  • Sensitive breeds like bubble eyes and celestial goldfish have fluid- filled sacs under their eyes that are easily damaged
