How Much Do Butterfly Goldfish Cost?

Specimens of butterfly goldfish may be fairly costly. This is due to the fact that they are not often produced for pet shops, therefore you may need to contact a goldfish breeder to get a good butterfly goldfish. The butterfly goldfish may cost anywhere from $20 to $80 depending on the design and colors. Shipping fees often range from $25 to $60, and when combined with the price of the goldfish, it may result in a greater price than other goldfish.

Typical Behavior & Temperament

Butterfly goldfish are placid fish with a low level of hostility. They thrive in groups with other elegant goldfish and form strong bonds with their owners. Butterfly goldfish are slow-moving fish which want to live in a big aquarium. If maintained in a tiny tank, they are quickly agitated, although they may also be kept in indoor or patio ponds. They seldom fin nip and don’t pay much attention to other fish. Butterfly goldfish with thick fins and bodies are more prone to float a few inches above the aquarium’s bottom and rest often.

Appearance & Varieties

The egg-shaped butterfly goldfish has a small, stubby body. The head is larger than the body, and it is equipped with a pair of telescopic eyes. When properly cared for and kept in huge pools of water, they may reach a size of 6 to 8 inches.

They live for an average of 8 to 10 years, although well-cared-for butterfly goldfish may live for up to 12 years. The butterfly trail is the species’ most notable characteristic. The goldfish’s status is determined by its tail, which should not be excessively little or huge in comparison to the rest of their body.

The tail is horizontally positioned, and the body is rather deep. The tail lobes are formed like outspread butterfly wings, which is a lovely complement to the rest of their appearance. The dorsal fins of the Ryukin goldfish are tall and contain a hump. The body resembles that of a Ryukin, and the butterfly goldfish was most likely created by breeding a telescope goldfish with another telescope goldfish.

They are available in a variety of designs and hues, including reds, whites, pandas, orange, and black.

How to Take Care of Butterfly Goldfish


Habitat, Tank Conditions & Setup

Tank/aquarium size

A regular rectangular tank of at least 20 gallons is required for butterfly goldfish. When placed in bowls, vases, or bio-orbs, they do not thrive. Tall aquariums are unsuitable for these goldfish, since they may suffocate. These goldfish have a hard time swimming and like to stay towards the bottom of the aquarium. They can’t acquire oxygen from the surface if the tank’s height exceeds its length. Adult butterfly goldfish thrive in kiddie pools that have been converted into goldfish habitats, ponds, and huge basins. At least a 40 gallon aquarium is required for fully developed adult butterfly goldfish.

Water temperature & pH

These goldfish can survive a wide range of temperatures, although they thrive in water that is somewhat warmer. The tank’s principal temperature should be between 62°F and 77°F (17°C and 25°C). For them to remain healthy, the pH should be between 6.0 and 8.0.

Foraging on a substrate is a terrific method to enhance their life and stimulate activity for all goldfish species. Butterfly goldfish thrive with fine gravel or aquarium sand as a substrate. To avoid choking, the gravel should be small enough to fit in their mouths and readily spit out.


In their tank, butterfly goldfish should have a few live plants. This provides them with a fiber-rich snack that aids digestion. Live plants also provide them a place to hide and help them feel more at ease in their surroundings.


Warm-toned lighting, rather than brilliant white LED lights, are preferred by butterfly goldfish. It is preferable to use a light with a warm orange glow, blue, or green hue. You may also utilize lights with a dusk and dawn setting that have a timer.


Because butterfly goldfish are notoriously filthy, they demand a tank with a high level of filtration. They generate a lot of waste, which raises the bioload in their tank. They should have an aeration system as well as a filter, and they should change the water often.

Are Butterfly Goldfish Good Tank Mates?

Butterfly goldfish should be kept in a tank designed specifically for them. Other varieties of fish and shrimp do not get along with them. Butterfly goldfish thrive in the company of other exotic species like Orandas, Ranchu, Ryukin, Fantails, and Telescope goldfish.

Tropical fish and crustaceans should never be kept with them. When the goldfish get big enough, they will generally consume smaller tank mates since the temperatures are dramatically different. Large apple snails are a suitable tank companion for butterfly goldfish. The goldfish will devour the smaller snails, putting them at danger of choking.

What Should You Feed a Butterfly Goldfish?

Natural omnivores, butterfly goldfish need a diet rich in both plant and protein-based materials. As a staple diet, a portion of high-quality food is advised, with living foods and supplements served as snacks.

The high protein content of a butterfly goldfish’s food might cause digestive issues like constipation. To improve digestion and reduce their risks of getting bloat, they need a lot of plant and algal elements. Excess bloat may create issues with their swim bladder organs, causing them to become unbalanced in the water.

Healthy snack options include deshelled peas, blanched romaine lettuce, spinach, zucchini, and cucumber. Live or freeze-dried items like bloodworms, insect larvae, tubifex worms, or brine shrimp may be fed to your butterfly goldfish. Protein levels in juvenile goldfish should be greater since they will be using the nutrients to develop. When they reach the age of two, the protein amount should be reduced.

Taking Care of Your Butterfly Goldfish

Step 1: Get a big tank for your butterfly goldfish. Follow the simple rule of 20 gallons for one juvenile butterfly goldfish and 10 gallons for each additional goldfish when stocking. If you’re going to keep your butterfly goldfish in a pond, make sure it’s spherical to prevent them from getting stuck in tight corners.

Step 2: Install a powerful filter in your butterfly goldfish’s tank to house helpful microorganisms that convert ammonia to nitrates. Before introducing your new butterfly goldfish, the tank should be cycled for several weeks.

Step 3: To enhance oxygenation, keep an air stone within the tank. To ensure aeration for your butterfly telescopes, the surface should be continually moving.

Step 4: Use a liquid testing kit to test the water. 0 ppm ammonia and nitrite, and 5 to 25 ppm nitrate, according to the measurement. Weekly water changes are recommended to reduce the build-up of contaminants in the water.

Step 5: To meet the nutritional demands of butterfly goldfish, feed them a nutritious and comprehensive diet. Freshness is essential in all meals, and commercial items should be consumed long before their expiration date. Soaking items before feeding can leech out the nutrients that your goldfish need.


Butterfly goldfish should be kept in mixed groups of males and females in order to reproduce properly. A three-to-one female-to-male ratio will suffice. You should set up a breeding tank or spawning mop to provide a safe haven for their eggs and young. Butterfly goldfish have no maternal instincts and will devour their young. The breeding tank should include a heater, filter, and aeration system.

If you want your butterfly goldfish to reproduce, offer them live meals every other day and gradually raise the temperature over the course of a week. They’ll be encouraged to spawn as soon as the temperature lowers again, and the female will lay her eggs throughout the tank’s plants. The eggs will subsequently be fertilized by the male butterfly goldfish. External fertilization is used, and both genders are necessary in the breeding process.

Is a Butterfly Goldfish Aquarium a Good Idea?

Butterfly goldfish are a fantastic stocking choice if you have a big tank with a filter and aeration system. They will offer character and color to a variety of domestic tanks or ponds, as well as a captivating view from above and on the side.

Butterfly goldfish may be added to existing aquariums that already include fancy goldfish. They’ll get along with a variety of goldfish varieties and appreciate the companionship. We hope that this article has given you a better understanding of the butterfly goldfish’s needs!
