What is a butterfly fantasy goldfish?

The butterfly goldfish is a beautiful and unique variety of goldfish, perfect for any aquarium. They are easy to care for and make a great addition to any freshwater tank. These peaceful fish are also known as butterfly goldfish, telescope butterfly goldfish, or simply fancy goldfish.


These fish are native to China and were first bred during the Tang dynasty (618-907 AD). They were initially developed for use in ponds and lakes, but have since become popular aquarium fish. Due to their long fins, butterfly fantasy goldfish are not suitable for life in the wild. In their natural habitat, they would be easy prey for predators.

The butterfly goldfish is a popular choice among goldfish enthusiasts due to its unique appearance. They are also considered one of the hardiest breeds of goldfish and are good for beginners.

Physical appearance

As their name suggests, butterfly fantasy goldfish have long tail fins that resemble the wings of a butterfly. They also have a flat body shape, typical of slender-bodied goldfish. Butterfly fantasy goldfish come in various colors including orange, black, yellow, and white.

This species of goldfish typically grows to 6-8 inches (15-20 cm) in length and 2.2 ounces (62 grams). Although you can purchase these fish for around $50, prized cans of butterfly goldfish specimens fetch hundreds or even thousands of dollars!

Regardless of their price, butterfly fantasy goldfish are a beautiful addition to any aquarium. These fish are an excellent choice for goldfish collectors looking for a unique fish to add to their collection.

Life expectancy

The lifespan of a butterfly fancy goldfish is typically 8 to 10 years, but they have been known to live up to 12 years in captivity. Like most exotic goldfish, these fish have a shorter lifespan than their common cousins.

The lifespan of your elegant fantail goldfish will depend on several factors, including diet, water quality, and tank size. By giving your fish the best care possible, you can help them live long and happy lives.

care guide

As mentioned, butterfly fancy goldfish are easy to care for and are a great choice for beginners. In this section, we’ll go over everything you need to know to keep your graceful butterflyfish healthy and happy.

Choose a suitable size tank

When choosing a tank for your graceful butterfly goldfish, your goal should be to give your fish plenty of room. You need to allocate at least 30 gallons per fish, so for every additional goldfish you add to your tank, you’ll need to increase your tank size by 30 gallons.

It is also important to choose a goldfish tank with plenty of open space to swim. Butterflytail goldfish are not particularly active fish, but they still need room to move. A long, rectangular tank is a good option for these fish, as it will give them plenty of room to swim.

use a filter

As with all goldfish, a strong filter goes a long way in maintaining water quality. Goldfish are notoriously messy eaters and produce large amounts of waste, so having a good filtration system is essential to keeping your tank clean. Many experienced fish keepers consider this an integral part of standard-quality goldfish care: without a filter, your goldfish simply won’t thrive.

There are a variety of filters on the market, but we recommend choosing a cartridge filter for your fancy butterfly fish tank. Cartridge filters are powerful and efficient, and they do an excellent job of keeping your water clean. You can also opt for a power filter, but be sure to choose one rated for an aquarium of your size.

A filter can do a lot of the heavy lifting in maintaining goldfish water quality. Still, regular water changes should remain an integral part of your tank maintenance routine. Do a 20-25% partial water change once a week to keep the water clean and fresh.

Add some live plants

While live plants are not essential to keeping goldfish, they can provide a more natural environment for them. Live plants also help keep the water clean by absorbing excess nutrients and providing shelter for fish. Also, the base of the plants can help anchor the gravel and prevent it from being churned up by the filter.

Many species of goldfish enjoy nibbling on aquatic plants, so be sure to choose goldfish-friendly plants. Good plant choices for fancy figure goldfish tanks include Java ferns, anubias, and hornwort. These plants are hardy and can take a fair amount of abuse from curious goldfish. If you’re looking for something a little more delicate, consider adding some floating plants to your tank.

Butterfly fantasy goldfish may be some of the most beautiful fish around, but the aesthetic appeal of your tank will still benefit from the natural, organic beauty of live plants.

Choose the right substrate

When choosing a substrate for butterfly goldfish, there are a few things you’ll need to keep in mind. First, you’ll want to choose a substrate that is smooth and won’t scratch your fish’s delicate skin. Butterflytail goldfish are known for their wide tail spread, which makes them susceptible to damage from sharp or abrasive substrates.

Second, you’ll want to choose a substrate that won’t upset the delicate pH balance of your goldfish tank. Goldfish are sensitive to changes in pH, and even a small change can cause serious problems for your fish. Therefore, we recommend choosing a neutral substrate such as gravel or sand.

Finally, you’ll want to make sure your substrate is safe for goldfish to consume. Many goldfish are known for their tendency to nibble on substrates, and ingesting the wrong type of substrate can cause digestive problems or even death. If you are not sure if a particular substrate is safe for goldfish, it is always best to err on the side of caution and choose another.

decorate your tank

Now that you’ve chosen the perfect substrate and added some live plants to your tank, it’s time to start decorating! When it comes to goldfish tanks, the sky is the limit when it comes to decoration. You can choose from a wide variety of artificial plants, rocks, and other decorations to create a unique look for your tank.

Just be sure to avoid decorations made with materials that are toxic or pose a choking hazard to your goldfish. Also, be sure to avoid decorations with sharp edges that could damage your fish’s delicate fins.

When choosing a bottom for your tank, you have a few different options. You can choose from a wide variety of commercially available backgrounds, or you can create your own custom background using acrylic paint or contact paper.

If you decide to paint your bottom, use non-toxic paint that won’t harm your fish if it comes into contact with water. You’ll also want to make sure the paint is completely dry before adding your goldfish.

Butterfly Fancy Goldfish Feeding Guide

Now that we’ve covered the basics of setting up a butterfly goldfish tank, it’s time to talk about feeding your fish. As with all goldfish, diet keeps your butterfly goldfish healthy and happy. Here are some tips to help you choose the best food for your fish.

Use high-quality fish flakes as a staple diet

Goldfish are omnivores, which means they will eat both plants and animals. In the wild, goldfish consume a variety of foods, including algae, crustaceans, and insects. However, in captivity, goldfish are generally fed a diet of pellets or fish flakes.

While there are many goldfish foods available on the market, we recommend using high-quality fish flakes as the staple diet for your butterfly goldfish. Fish Flakes are specially formulated to provide all the nutrients and minerals elegant goldfish types need to stay healthy and thrive. In addition, the fish flakes are highly digestible and will not cause problems to the fish’s digestive system.

One potential problem goldfish owners may run into is determining which brand or type of fish food best provides their elegant goldfish’s high-quality diet. To help make your decision easier, we’ve compiled a list of our favorite fish flakes for goldfish!

You can also seek recommendations from your local fish and pet stores. These stores often have a wide variety of goldfish food options available and can help you choose the best food for your fish.

Offer live, frozen, or freeze-dried foods as treats

In addition to a high-quality diet of fish flakes, you should also offer live, frozen, or freeze-dried foods as occasional treats. These foods are a great way to give your goldfish a high-quality, varied diet that will help keep them healthy and happy.

Although most of your fish’s nutritional needs should be met from their staple diet, offering live, frozen or freeze-dried foods as treats will help ensure your goldfish get all the nutrients they need in a complete diet.

Some excellent live, frozen, or freeze-dried foods for butterfly goldfish include brine shrimp, daphnia, bloodworms, insect larvae, and tubifex worms. You can usually find these foods at local fish stores or online. When feeding your goldfish live food, it is important to offer only a small amount to avoid overfeeding.

Also, be sure to only offer live, frozen, or freeze-dried foods as occasional treats. These foods should not make up the majority of the fish’s diet, as they can cause digestive problems if eaten in large quantities. Remember: your staple diet should consist primarily of high-quality fish flakes.

Choose Foods Appropriate for Life Stage

This may seem confusing at first, but it’s pretty simple. When choosing food for your butterfly goldfish, you’ll want to make sure you’re choosing an option that’s appropriate for their life stage. In other words, you’ll want to make sure the food you’re feeding your fish is appropriate for their current life stage.

For example, juvenile butterfly goldfish require a high-protein diet to help them grow and develop properly. On the other hand, adult butterfly goldfish require a low-protein, high-carbohydrate diet to maintain their health and energy levels. Pregnant or egg-bearing females also have different dietary needs than non-breeding fish.

Many goldfish food manufacturers offer specially formulated foods for different life stages to make things a little easier. A distinction is often made between feeds for juvenile fish, adult fish and brood fish. These foods are an excellent choice for goldfish owners as they provide the nutrients and minerals your fish need at their specific life stage.

Introduce a small amount of plant matter

Sometimes it’s easy to forget that goldfish are omnivorous fish that require plant and animal matter. Goldfish graze on aquatic plants and algae to meet their nutritional needs in the wild. In captivity, goldfish owners often overlook the importance of plant matter in their fish’s diet.

While the majority of your goldfish’s diet should still consist of high-quality fish food, you should also offer it a small amount of plant matter on a regular basis. This can be in the form of blanched vegetables like spinach, zucchini, or lettuce. Offering a small amount of plant matter to your goldfish will help ensure they get all the nutrients they need for good health.

Another reason to offer plant matter to your goldfish is that it improves your fish’s digestive health. Butterfly goldfish are known to be delicate fish with sensitive digestive systems. By regularly offering a small amount of plant matter, you can help keep your goldfish’s digestive system healthy and functioning properly. The last thing you want is to have a constipated fish on your hands!

Remember not to overfeed!

Last but not least, it is important to remember not to overfeed your graceful butterfly goldfish. As a general rule, you should only offer your fish as much food as they can consume in two minutes. Any more than that and you risk overfeeding and contaminating your tank water.

Overfeeding is one of the most common problems among goldfish owners, so it’s important to be mindful of how much food you feed your goldfish. A great way to avoid overeating is to measure out the right amount of food before mealtime. Remember to feed the fish only during feeding hours and remove any uneaten food from the tank afterward.

By following these simple tips, you can ensure your butterfly fancy goldfish are getting the nutrients they need for good health. A healthy diet is essential for all goldfish, but is especially important for delicate fish like butterfly goldfish. With a little effort, you can help your fish live a long and healthy life.

Where to Buy an Elegant Butterfly Goldfish

After reading all of the above, we hope that you are now interested in purchasing your own butterfly goldfish! The next step is to find reputable goldfish breeders who can provide you with healthy, well-cared-for goldfish.

There are many places that sell goldfish, but they are not all the same. Some breeders only deal with show quality butterfly goldfish, while others are content to meet the more general standard of pet goldfish.

If you’re buying from the former, you can expect to pay a pretty penny for your fish. The latter, on the other hand, will be much more affordable.

When choosing a breeder, it is important to do your research and obtain a high quality bred goldfish. A good breeder will provide you with information about the goldfish family, the different types of goldfish, and the care required for each type. They should also be able to answer any questions you have about goldfish care.

Choosing a breeder is an important decision, so take your time and choose wisely. A little research can save you a lot of headaches (and money) in the future!

Goldfish Fancy Butterfly Breeding

If you are interested in raising your own butterfly goldfish, there are a few things you need to know. First, it is important to have a female and a male fish. You can tell the difference between the two by looking at their fins; males will have longer fins than females. Second, you will need to set up a breeding tank. This tank must be at least 10 gallons and have a sponge filter.

It is also important to provide plenty of hiding places in the breeding tank for your fish. Breeding tanks should have plenty of plants, rocks, and other objects that the fish can use for shelter.

This is important because when it is time to spawn, the female goldfish will lay her eggs in a hidden area. The male goldfish will then fertilize the eggs.

After laying the eggs, they will hatch in about two days. The fry (baby fish) will be free-swimming after five to seven days. At this point, you can start feeding them brine shrimp or flaked food.

Tank Mates for Butterfly Fancy Goldfish

Butterfly goldfish are best kept with other peaceful fish that do not disturb them. Good tank mates for butterfly goldfish include:

  • plecos
  • Catfish
  • tetras
  • danios
  • Other fancy goldfish

It is important to avoid having butterfly goldfish with aggressive fish such as cichlids or bettas. These aggressive fish can intimidate or even kill your delicate butterfly fish.

When choosing tankmates for your graceful butterfly goldfish, it is also important to consider the size of the fish. Butterfly goldfish can get quite large, so it’s best to avoid keeping them with smaller fish that can be easily swallowed.


Butterfly Fancy Goldfish are a beautiful and unique type of goldfish that are a great addition to any fish tank. While they are not the easiest fish to care for, they are certainly worth the effort. With a little knowledge and careful planning, you can be successful in keeping your butterfly goldfish healthy and happy.
