Bubble Goldfish – Why do Bubble Eye Goldfish have Bubbles?

Bubble Goldfish
(Last Updated On: April 13, 2021)

The most striking feature of the Bubble Eye Goldfish is its bubbles. The bubbles of these goldfish begin to develop at the age of 6-9 months, leading to what is known as the water-bubble eye.

The bubbles are very big as this goldfish is 2 years old. These water-filled bubbles actually become so large that they can make it difficult to see and swim with the fish.

These fancy goldfish have a very attractive appearance but their bubbles break easily. The dishes are notorious for being caught in the water uptake valves of aquarium filters.

A foam cover on top of the valve will help prevent this. Most of the time, broken bubbles will grow again but will have different shapes and sizes that do not match the other bubbles.

Sometimes a broken bubble won’t grow at all. Additionally, broken bubbles slowly cure and are prone to infection, so keep an eye on your fish and be prepared for it when needed.

Bubble Eye Goldfish’s infamous bubbles

In addition to its infamous bubbles, Bubble Eye Goldfish is one of the most diverse of goldfish. Aside from the Lionhead Goldfish, the Bubble Eye Goldfish is dorsal-less, so there is no fin on the top behind it.

There is a dorsal fin of Bubble Eye Goldfish, a genus in China, but this species is not eligible for display by the American Goldfish Society (GFSA).

Bubble Eye Goldfish is one of the more rounded or egg-shaped fancy goldfish, which distinguishes it from the long, slender body seen in ordinary goldfish or shubinkins.

It has a double-tail, and the shape and size of the body are very similar to the Celestial Eye Goldfish. Bubble Eye’s eyes are as bright as Celestial’s, though not as extreme as Celestial’s.

Both of these goldfish have bodies that are somewhat thinner than other round or egg-shaped goldfish. Bubble Eye is available in a variety of goldfish colors, including red, blue, chocolate, and black; Red / white and red/black bi-color; and calicos.

Although bubble eye goldfish is widely available, it is considered fine and is not recommended primarily for fish or for community aquariums. The ability of bubble eye goldfish to swim is surrounded by its circular body and is further reduced in the absence of a stable dorsal fin.

The better tankmates will be similarly handicapped but the less powerful are Lionhead Goldfish, Telescope Goldfish, and Celestial Eye Goldfish. It may not win any races but should keep eating plenty of water-bubble eye goldfish if kept with other slow-moving varieties.

Distribution / Background

The goldfish of today is the Prussian Carp, the Silver Prussian carp, or the Jebel Carp, a genus of wild carp of the species known as Carassius gibelio (syn: Carassius auratus gibelio), which Bloch described in 1982.

These wild carp originated in Central Asia (Siberia). They live in slow and steady waters of rivers, lakes, ponds, and holes, feeding on plants, detritus, small crustaceans, and insects.

For many years, it was believed that the goldfish originated from the Crucian Carpus or Golden Carp Caraccius Caraccias described by Linnaeus in 1758.

This fish extends over the waters of the European continent, flowing north from England to Russia in the Scandinavian countries of this Arctic Circle and Southern France and the South as far as the Black Sea. However, recent genetic research more likely points to C. gibellio as an ancestor.

Goldfish originated in China. By the 1500s, goldfish were traded in Japan, reaching Europe in the 1600s and America in the 1800s. Much of the fancy goldfish was developed by Asian breeders.

We can see the results of centuries of perseverance in the great colors and shapes of today’s goldfish. Native goldfish are now distributed worldwide.

Bubble Eye Goldfish, also known as the water-bubble Eye Goldfish, was made in China. It is one of the fancy goldfish breeds of over 125 captive species.

Scientific name: Carassius auratus auratus
Social grouping: Groups – can be grouped singly or in groups.
IUCN Red List: NE – Not Assessed or Not Listed – There are no wild populations of this captive-bred breed.


Bubble eye goldfish, also known as Bubble Eye Goldfish, is an egg-shaped goldfish. It has a double-tail, and its shape and size are very similar to that of the Celestial Goldfish, which is slightly thinner than other egg-shaped goldfish. Also, like Celestial, its eyes are bright, though not as extreme.

Fluid bags begin to develop as bubbles under her eyes at 6-9 months of age. The bubbles are very big as they are 2 years old. It is one of the long-lived goldfish, although there is a dorsal fin of the genus China.

These bubble eye goldfishes are available in a variety of colors including red, blue, chocolate, and dense material in black; Red/white and red/black bi-color.

And calicos will usually reach about 5 inches (13 centimeters), though some hobbyists say their bubble eyelid growth is even bigger. The average goldfish’s lifespan is 10 – 15 years, though goldfish that survive 20 years or more are not uncommon in aquariums and ponds.

Fish size – inches: 5.0 inches (12.70 cm) – Although this fish is capable of larger sizes, it rarely drops more than five inches into the home aquarium.

Lifetime: 15 years – Average goldfish lifespan is 10 – 15 years, but they are known to survive well over 20 years if maintained well.

Difficulty in keeping fish

The bubble eye goldfish is one of the more important species of golden fish. They are not recommended as a primary fish or for community aquariums.

Unlike flat-bodied goldfish, they have a low tolerance for pollution. They will need good care and lots of space. When it comes to feeding, they will not succeed with fast, competitive tank mates.

Be careful when casting nets for these fish’s eyes are easily damaged. Also, be careful about taking filters. If there is a strong water flow, the bubbles of these fish can be eaten and burst on top. Adding some soft sponge filter media to the feeding valve can help.

Many people put goldfish in a small one or two-gallon bowl without any heaters or filtration. But for the best success in keeping the Bubble Eye Goldfish, provide them with the same filtration, especially the biological filtration that other aquarium residents enjoy.

Aquarium hardness: Moderately difficult – the pouch under the eyes is very fine. This fish is rarely insight and is a poor swimmer.

Accurist Experience Level: Intermediate – Accurist should be well acquainted with the specific requirements for goldfish care and variations.

Food and feeding

Since they are ubiquitous, Bubble Eye Goldfish usually eat all kinds of fresh, frosted, and flake foods to maintain a good balance, giving them a high-quality flak meal daily.

To take care of your bubble eye goldfish, feed brine shrimp as treats (either live or frozen), blood worms, daphnia or tubifex worms. Fiz-dried foods are generally preferred foods to avoid parasites and bacterial infections.

Due to the fluid-filled sac under their eyes, the eyes of the bubble are very short. This makes it more difficult to see their diet and it means they need extra time to feed.

Diet Type: Omnivore
Flake Food: Yes – this fish should be best fed with sinking food because it appears to be very prone to air attacks, which can create health problems for fish.
Tablet / s: Yes
Live food (fish, shrimp, worm): Some diets
Vegetable meal: Some diet
Meat meal: Some kind of diet
Frequency of feeding: Several feedings per day – These fish will compete while feeding other goldfish, except for obstacles in sight and swimming.

Aquarium Care

This bubble eye goldfish needs a good maintenance tank to stay healthy. The minimum tank size is 10 gallons, so make sure water changes are frequent.

It is advisable to change 1/3 to 1/3 of the regular water daily to keep these fish healthy. Snails can be associated with reducing the algae in the tank, helping to keep it clean.

Water changes: Weekly – Goldfish produce more waste than other freshwater fish and benefit greatly from frequent water changes.

Aquarium setup

Setting up a bubble eye goldfish aquarium that will keep your fish happy and healthy is the first step to success. The shape and size of the aquarium are important and depend on the amount of goldfish you are about to keep. These fish require a lot of oxygen and produce a lot of waste.

Good filtration, especially organic filtration, is very helpful in maintaining the aquarium’s water quality. The filtration system will remove a lot of detritus, excess food, and waste that keep the tank clean and maintain the general health of the goldfish.

However, the water uptake of aquarium filters in the Bubble Eye Goldfish bag is notorious for being caught in the valve. A foam cover over the valve will help prevent this.

When choosing a bubble eye goldfish aquarium, consider the tank’s parameters:

The size of the tank

The ten gallons is the absolute minimum to hold a bubble of eye goldfish. It’s best to start with a 20 – 30 gallon tank for your first bubble eye goldfish, and then increase the tank size by 10 gallons for each additional goldfish. Providing plenty of water per fish will help reduce the amount of waste and reduce the number of water changes needed.

Always provide the highest amount of fieldwork. A large surface area reduces the likelihood that goldfish will suffer from oxygen deficiency. The surface area is determined by the size of the tank.

For example, a protruding tank provides more surface area (and oxygen) than a longer tank. Oval or circular tanks that are wide in the middle and narrow at the top can be filled less than full to maximize surface area.

Number of fish

A common rule of thumb for teens is 1 inch of fish (2.54 cm) per 1 gallon of water. However, this rule only applies to young fish. Large bubble eye goldfish consume a lot more oxygen than young fish, so maintaining this source of growing fish will stunt them and can contribute to disease and even death.

Size and growth of fish

For proper development, either buy less than the maximum number of fish or prepare to get a larger tank. Do not overlook the aquarium to prevent stunted growth and other health problems.

The goldfish is a cold-water fish and will do its best at temperatures between 65 – 72 65 F (18 ° – 22 ° C). Unlike flat-bodied goldfish, the Bubble Eye Goldfish cannot withstand temperatures less than 60 ° F (16 ° C).

Provide a pebble layer to help create a natural and comfortable environment for your fish. You can add some decoration, but keep in mind that its fluid-filled eye bag can be a problem, both are easily damaged and give these fish poor eyesight.

Make sure all the ornamentation is smooth with no stretch points or sharp edges. Smooth rock or driftwood, if anything, should be used sparingly.

Aquarium plants will be the best choice for aquarium decoration for goldfish but unfortunately, these fish are miners. As a result, live plants can be uprooted. Artificial plants make a good alternative and silk plants are safer than plastic.

A cover for the tank is desired, as it reduces evaporation and although they are not risky for jumping, some goldfish will jump out on occasion.

Luminosity is not essential for goldfish in general, but it can help Bubble Eye because the sight of these fish is very low. This makes the aquarium a great showpiece and is a must if you have a living plant.

Goldfish are freshwater fish, but they have some tolerance for some of the shaking waters. The salinity level must be kept low for C Aratus, with specific gravity below 10% with less than 1.12.

Minimum tank size: 10 gallons (38 l) – Ten gallons is the minimum required to hold this fish. It has high oxygen requirements and produces a lot of waste. If it is kept in a small aquarium, it will have very stunt growth.

Suitable for Nano Tank: Sometimes

Substrate Type: Any – A medium-sized pebble works best.

Needs Illumination: Medium – Normal Light – Strong light will help this fish optimize its sight a little.
Temperatures: -0.8 to -0.01 ° F (0.5 to 22.2 ° C) – Unlike gold body type goldfish, the Bubble Eye Goldfish temperature is higher than 1 ° F (5 ° C). Can’t do
Reproductive Temperature: – In the wild, in the spring the golden fish water is spread when the temperature of the water is about 5 ° F (20 ° C).
Range pH: 6.0-8.0
Hardness Range: 5 – 19 DGH
Brackish: Sometimes – salinity must be below 10% for C aortas, with a specific gravity less than 1.002.
Water movement: Weak – This fish requires light water flow. Its rounded body and lack of a stable dorsal fin made it swim.
Water Zone: All – This fish is generally preferred at the bottom or bottom of the aquarium.

Social behavior

Goldfish are very social animals and great community fish and they are also great scavengers. When you have a goldfish, it is not really necessary to add other scavengers or other bottom feeders to the aquarium.

When choosing a tank mate for this fancy goldfish, keep in mind the physical features of the bubble eye. Bubble IOs like Telescope Goldfish and Celestial Goldfish may be visually impaired.

Additionally, its swimming ability is constrained by its rounded body and lack of a stable dorsal fin, a feature that is also seen in Lionshead goldfish.

While Bubble Eye cannot easily compete for food with a fast swim type of goldfish, it can make a good companion to any of the similarly disabled varieties. They do it well with their own style.

black bubble eye goldfish

Toxic: No.
Nature: Peaceful
Same breed – Conspiracy: Yes
Peaceful Fish (): Safe
Slow Swim & Eat (): Safe
Shrimp, crabs, snails: Safe – Not aggressive
Plants: Threats – Goldfish will eat a variety of aquatic plants. In their endless quest for food, they can uproot the trees they do not eat.

Gender: Sex differences

During the breeding season, males have white turtles whose breeding is tubercles, with their coverings over the head and head. As seen from above, any female will look fat when laying eggs.

It is impossible to have sex with the goldfish during the breeding season, but the males are generally smaller and more slender than the males.

Breeding / Reproduction

Bubble Eye Goldfish is the layer of eggs that spreads easily under the right circumstances. They can be bred into small groups of up to five individuals, but they are also very social animals and have the potential to breed in larger groups.

The only time goldfish will sit in the wild is when spring comes. To disperse these into the aquarium, you need to duplicate the conditions found in nature.

Provide at least 20 gallons of aquarium and make sure the fish is healthy and disease-free. Some breeders recommend you treat the parasite. Many breeders will separate males and females for several weeks before breeding so that they increase their interest inspanning.

Simultaneously introduce the fish in the breeding tank. The tank needs a nice environment to adhere to the spanking process and the eggs need a strong environment for bushy, oxygenating plants, such as anchorage, although artificial plants or fibrous spanning mops can also be used.

To induce spawning, the temperature can be gradually lowered to about 60০ degrees F (5 degrees C) and then gradually warmed to 3 degrees F (2 degrees C) daily until dry.

Spanning begins when the temperature is between 4 ° C and 74 ° C (20 ° C – 20 ° C). At this time, high-protein foods such as live brine shrimp and worm feeding also stimulate spanning.

Feed small amounts three times a day, but do not overeat. Obsolete scraps will sink to the bottom and fill with water. Maintain a breeding tank with partial water changes up to about 20% per day.

Before spawning, as the temperature rises, men will chase their wives around the aquarium in non-invasive ways. This can last for several days and the fish will be more intense with color.

During the span, the fish will be scattered from side to side, and the males will press the female against the tree. It encourages the wife to lay down the small eggs that men will then fertilize.

Eggs will be adhered to by plants or spun mops by sticky straws. Spanning can last two or three hours and can produce up to 10,000 eggs.

At this point, parents will start to eat as many eggs as they can find. Because of this, it is best to remove the parents after the spanning is over. The fertilized egg will hatch within 4 to 7 days, depending on the temperature.

You can eat freshly decorated goldfish specialty fried foods until they grow up to be like a flake or brine shrimp, or you can serve the same food as long as you feed your parents until it is a little crunchy.

First, the fries are dark brown or black in order to hide better and not to eat large fish. They attain their adult color after several months, and when grown to about 1 inch tall, they can be kept with large size fish.

Breeding is easy: moderate

Diseases of fish

Properly maintained goldfish aquariums or ponds, goldfish are often preventable. Nevertheless, goldfish can cause illness and if left untreated can prove fatal. While goldfish are harsh, most will recover completely if treated on time.

When treating individuals, it is best to transfer the affected fish to a separate tank with no gravel or vegetation and make regular partial water changes. However, if the disease is evident throughout the main tank, it is best to treat it there.

Whether treated in a hospital tank or in your main tank, read and follow the manufacturer’s instructions for any medication. Some drugs can adversely affect water quality by destroying beneficial bacteria.

You have to remove carbon from the filtration system, taking many drugs that make carbon treatment ineffective.

Diseases of goldfish are similar to many that affect other freshwater fish, and the symptoms and treatment of goldfish are similar. Major types of fish diseases include bacterial infections, fungal infections, parasites, and protozoa including injuries, poor nutrition, or other ailments due to poor water conditions.

Bubble Goldfish

One of the most common problems is itch, which is a protozoan disease. Easy to identify because your fish looks like it was sprinkled with salt. Although itch is easily treated like other protozoan diseases, it can be fatal if not caught quickly.

Some other protozoan diseases are Costa, which causes cloudy skin, and Chilodonella, which causes blue-white cloudiness on the skin.

External parasites are also fairly common, but they are easy to treat and usually not fatal when treated. These include flukes, which are flat 1-mm long flat hookworms around the mouth. They attack fish shells or bodies.

Another type of parasite is the fish lizard (Argulus), a flat, mite-like crustacean about 5 mm long that attaches itself to the body of the goldfish. After all, anchor worms look like threads from fish.

Some bacterial infections include droppings, a kidney infection that can be fatal if left untreated. The tuberculosis of the fish is triggered by fish emaciated (having an empty stomach). For this illness, there is no perfect cure, and it can be fatal.

The tail/fin rot can also be bacterial, although the reduced tail or fin may also be due to a variety of factors. There are fungi, fungal infections, and even black spots or black eyes that are parasitic infections.

Swimming bladder disease is an illness that is indicated by abnormal patterns of fish to swim in and difficulty maintaining their balance.

This can be caused by a number of things: constipation, poor nutrition, physical deformity or parasitic infection Frozen pea-feeding (defrosted) has been noted to reduce symptoms and in some cases help to correct the problem.

Other miscellaneous illnesses include Cloud Eye, which can cause a variety of things, ranging from poor nutrition, poor water quality, and rough handling.

It can also be the result of other illnesses such as bacterial infections, infection with loss of appetite, and swelling in the body and the cause is often diet and then there are wounds and ulcers.

The wounds can become infected, causing ulcers. The lesions can develop either a bacterial or fungal infection or both and need to be treated.

Each of these diseases undergoes a variety of separate treatments and treatments. For more in-depth information on Goldfish Disease and Illness, see Goldfish Care; Fancy Goldfish and Goldfish Diseases.
