Which is the hardiest goldfish

Common goldfish most resemble their ancestor, the carp, and have a forked caudal tail fin with a smooth body. If kept in a pond, common goldfish can grow well over a foot long. These fish are available in many colors, including red, black, orange, white, yellow, and bronze. You can also find them in a combination of colors. Common goldfish are an excellent choice for beginners as long as tank requirements are met.

Comet Goldfish — Like common goldfish, comet goldfish have a slim body with stiff fins. Like commons, comet goldfish are very hardy and can be kept in ponds usually without a problem.

They also come in many colors and are excellent beginner goldfish. Shubunkin Goldfish — These fish are also recommended for novice goldfish owners and are recognizable by their beautiful calico pattern pattern includes orange, yellow, red, brown, black, grey, white, purple, and blue colors. Like most slim-bodied goldfish, shubunkins are very hardy, competitive eaters, and fast swimmers.

Egg-shaped Goldfish Also known as fancy goldfish, egg-shaped goldfish are very sensitive to poor water quality conditions. For this reason, many fancy goldfish are only recommended for experienced fish owners.

Most fancy goldfish have distorted swim bladders because of their egg-shaped bodies that can cause problems in poor water conditions — and even cause the fish to swim at a downward angle. If you do keep both goldfish types together, you risk frequent fin nipping, fancy varieties not getting enough to eat, and other problems.

Many fancy goldfish also have very delicate features bubble-eye goldfish, for example that can easily tear at the slightest nip, making it even more imperative that these goldfish are kept away from fast-moving fish. Like all common goldfish types, fancy goldfish do just fine if water conditions are met and you take safety precautions when handling or feeding. Fancy goldfish prefer 20 gallons 76 liters of aquarium water at the very minimum, with 10 gallons 38 liters for each additional fish.

Fantail goldfish are recognizable for their split caudal fin and are typically found in orange or calico colorations, though other colors are also available. They look a lot like fantail goldfish but with slightly rounder bodies and a more distorted swim bladder.

Their long fins are very sensitive to goldfish diseases and tears. Telescope Goldfish — Telescope goldfish have very limited vision because of their protruding eyes which resemble telescope lenses. The body of a telescope goldfish is very similar to a veiltail goldfish. Telescope goldfish come in all sorts of colors.

Because of their limited vision, they make poor competitors for food if kept with slim-bodied goldfish. These fish are usually best handled by intermediate goldfish owners. Unlike other common goldfish types, black moors are fine pets for beginners and can even survive well in outdoor ponds. Lionhead goldfish are named after the fleshy hood that surrounds their face, except for the eyes, mouth, and nostrils. Oranda Goldfish — Like lionheads, oranda goldfish have a similar headgrowth also called the wen , though it only develops on the top of the head and slightly on the sides of the head as well.

Oranda goldfish resemble fantails in body shape and are very slow moving. Celestial Goldfish — Celestial goldfish have limited eyesight, since the eyes are actually locked upwards almost like the fish is gazing at the sky. For this reason, the Chinese often call celestial goldfish stargazers. Celestial goldfish should only be kept by advanced goldfish hobbyists. They lack a dorsal fin and are slow moving, compared to slim-bodied fish and other common goldfish types.

They tend to feel their way around the aquarium or position their body in a way that allows them to see forward. Bubble Eye Goldfish — One of the most fragile common goldfish types around, bubble eye goldfish develop very delicate fluid-filled sacs beneath their eyes.

They spend most of their time resting on the aquarium bottom. Sharp rocks can easily burst the sacs beneath their eyes and attract goldfish diseases.

Like lionhead goldfish, these fish have no dorsal fin. The latter are the hardy varieties and can easily survive winter weather as long as the pond is deep enough not to freeze all the way to the bottom.

This type of goldfish is the hardiest of all the varieties and is best able to survive in an outdoor environment. These grow to become very large fish, often achieving lengths of 12 to 18 inches. The common goldfish retains the same basic shape as its wild cousins but is more colorful. These fish swim fast, hide easily and compete well for food. Common goldfish survive in near-freezing temperatures but tend to outgrow their aquarium homes quickly. Comets are often mistaken for common goldfish, as they look roughly the same except for body shape and tail length.

These fish are aptly named due to their fast swimming speed and can be difficult to catch. Comets are longer and thinner than the common goldfish and many also have longer tails. This species grows large in size between 12 and 18 inches long , is brightly colored, and is active in nature. They originated in East Asia and are a member of the carp family. Now that you know the common goldfish is the hardiest, let us explore this topic further and in more detail. As we move through this article, I will discuss the different types of goldfish and how hardy each one is.

I will also explain what you can do to increase the lifespan of your goldfish and how to properly care for them. So, if you are ready to learn more about goldfish and their robust character, then please continue reading….

The common or standard goldfish, being the hardiest overall, tend to live the longest as well. If they are well cared for, they can survive for 25 years or more in captivity! When kept in a pond as opposed to a tank, common goldfish can live as long as they normally would in the wild. Their lifespan is shortened significantly, however, when kept in a fishbowl.

The common goldfish is generally easy to care for, provided it is kept in a well-maintained tank or pond. Since they are a type of cold-water fish, the common goldfish prefers temperatures around 60 to 70 degrees F. The pH level, though not critical, should be somewhere between 7. Perform weekly partial water changes and vacuum the substrate to remove excess food and waste once a month.

Feeding the common goldfish once a day is often enough. Give them only as much food as they can eat in a 2-minute time-period and remove any leftovers immediately afterwards. Being omnivores goldfish thrive on a plant and meat diet and should be fed a variety of foods, including algae wafers, fish flakes, fish pellets, brine shrimp, and bloodworms.

They will also eat the algae growing naturally in the tank. Bubble eye goldfish are smaller in size approximately 3 to 4 inches long and tend to live between 10 and 15 years in captivity. They are the slowest and smallest species of goldfish, which makes them more prone to predations. They are not as adaptable to diverse aquatic environments, making them more fragile and less hardy than others of their kind. Comet goldfish are much like common goldfish when it comes to hardiness.

The only real difference is in their appearance — the comets have longer, flowing fins and a heavily-forked tail. They can adapt to the coldest of temperatures, which is why they can be kept in an outdoor pond even in the winter months! Comet goldfish are brightly colored and fast swimmers, making them a joy to observe. Fantail goldfish are much like the bubble eye in that they are fragile and not near as hardy as other types of goldfish. They also look to be humpbacked and grow to approximately 6 inches in length.

While beautiful and graceful in appearance, this species needs extra care to survive in captivity. Oranda or fancy goldfish vary in color with an outgrowth that covers their entire head, except for the eyes and mouth.

This species ranges in size from 8 to 12 inches long and requires special care as they are often prone to bacterial infections.
