Are Bubble Eye Goldfish Hard to Care for?

Goldfish come in a variety of breeds, each with different colors, patterns, and shapes. The bubble eye goldfish is one of the most unique types – its large, bulging eyes are particularly eye-catching, and they lend their name to the breed. This makes it a popular pet for aquarists.

There are a lot of different factors that go into caring for a bubble eye goldfish. Some people find them to be relatively easy to keep as a pet fish, and others have a lot more difficulty with them. In order to determine if you are one of the people who would have an easier time or a harder time caring for these types of fish, there are some things you need to consider and this article will talk about a few of those things.

What Is a Bubble Eye Goldfish?

The Bubble Eye Goldfish is part of the Fancy Goldfish clan, which has upward-pointing eyes paired with two large fluid-filled sacs. It's a dorsal-less fish that has a clean back and eye bubbles that are uniform in color and size.

Because these types of fish are so delicate, they should be maintained in a separate aquarium from boisterous types and sharp tank decor. Although the bubbles will regrow if punctured, an injury might make the fish susceptible to illnesses. The bubbles can harm the fish since it is not a strong swimmer and has a perplexing bobbing head at the surface due to the weight of the fluid-filled sacks.

According to Japanese researchers, the liquid in the bubble eye's sacs might be a growth stimulant. Scientists may draw the same fish every few months with a syringe and study the cells for information on how tissue heals and grows due to the eye sac's capacity to quickly regenerate and refill itself.

Bubble Eye Goldfish Size

The average size of a Bubble Eye Goldfish when fully grown is around 5 inches. These fish, unlike other Goldfish kinds, do not grow any larger after this point. This makes them an ideal small aquarium fish.

Bubble Eye Goldfish Lifespan 

The average lifespan of a Bubble Eye Goldfish is 10-15 years! The majority of goldfish can live longer than other freshwater fish, and the Bubble Eye is no exception. However, if you want them to live this long, you must give them the greatest care possible. Tank conditions and diet are the most important elements affecting the lifespan of this delicate species.

Bubble Eye Goldfish Appearance

The sacs beneath the eyes are the most distinctive feature of the Bubble Eye Goldfish. These aren't airtight, contrary to popular belief. Fluid is stored in them, causing the bubbles to jiggle as the fish swim. 

These sacs are very delicate and can rupture easily. Fortunately, the sacs can repair on their own and refill with fluids. The regrown sacs, on the other hand, are generally not as big as they were original. This may cause the fish to have an uneven appearance.

The size of the sacs varies from one individual to the next. They may be manageable on some fish. In other cases, they can grow to be so big that swimming becomes difficult. Because of this, they are considered poor swimmers.

Aside from that, the sacs obstruct the fish's vision causing them to have poor eyesight. The eyes are pointed upward and are positioned directly beneath the sacs. The round form of the sacs, along with their gaze, makes it difficult for the fish to know where they're heading.

These fish have some additional unusual physical features beyond their bubble eyes. They lack a dorsal fin, for one. Their backs are completely smooth. The absence of a dorsal fin may cause difficulties in the water.

The bubble eye goldfish has a twin-tailed body. The tailfin separates into four parts, with the tailfin itself being rather lengthy and offering some balance to the fish's body. The fish is spherical and egg-shaped in shape. They do have some pectoral fins and an anal fin, albeit in a restricted manner.

Bubble Eye Goldfish Colors

Bubble Eye Goldfish come in a variety of colors. The majority of these goldfish species are solid, but they may also be gold, orange, red, brown, or white. Some individuals have more than one hue. Fish with red and white markings, as well as red and black markings, are all possible. The calico bubble eye goldfish and red bubble eye goldfish are the most preferred ones.

Differentiating Between Male and Female

When it comes to sexing the fish, there aren't that many distinctions to be made. In most situations, it's difficult to tell the difference between juvenile and adult fish. You can start seeing differences when they're ready for breeding at full maturity.

The female fish will acquire a plumper appearance when they're fully grown. They'll also have a less streamlined shape. The male, on the other hand, will be slimmer and have a more tapered abdomen.

When it comes to the spawning season, the female's ovipositor tube will become visible. This is a small white protrusion that's located beneath the ventral fins (the pair of fins beside the anal fin) and the male fish will start developing fish tuberculosis.

Bubble Eye Goldfish Behavior

Bubble Eye Goldfish are considered ornamental fish. These goldfish varieties have a mellow disposition and are among the most laid-back fish available. They get along with all other peaceful species. They're not known to be nippy or aggressive in any way.

Because they lack a dorsal fin, these fish may have some trouble swimming. They may not be the most graceful fish in the world, but they get by just fine.

They're known to be social creatures and enjoy the company of others. Because of this, it's best to keep them in groups. A single Bubble Eye Goldfish will feel lonely and stressed in most situations. However, always make sure that you do not add any aggressive fish into the aquarium. 

Bubble Eye Goldfish Care

Bubble Eye Goldfish is not a simple breed to maintain. Because of their fragile bubbles, they need a specific setting in order to be safe. Not only that, but they also require certain stringent water standards in order for them to thrive.

The following is a list of things you'll need to take into consideration when caring for your Bubble Eye Goldfish:

Bubble Eye Goldfish Tank Setup 

Setting up the tank is arguably the biggest concern when caring for your Bubble Eye Goldfish. You'll need to make sure that this delicate fish has plenty of space and a safe environment.

  • Tank Size: Because these fish grow to be quite large, they need a spacious tank. A 10-gallon aquarium is a minimum tank size you should consider. If you want to keep a group together, provide each individual with an additional 10 gallons of water. The Bubble Eye Goldfish require considerably more area than a simple bowl. Furthermore, they generate a lot of waste that might quickly pollute the water in such a confined environment.
  • Water Parameters: You'll need to maintain the water quality in your fish tank. In order for them to survive and thrive, the water in their tank needs to be clean and well-oxygenated. You need to check the ammonia and nitrate levels on a regular basis. PH should be kept neutral (7). The temperature should ideally be between 65 - 75 degrees Fahrenheit. The water hardness should be between 5 - 19 dGH.
  • Filtration System: A filtration system is absolutely crucial to keep the fish tank clean. It will help ensure that your water remains clean and free of pollutants. Various filters are available on the market, so you may want to consider which one is best suited for your specific needs.

Tank Decor

Aquarium decor is essential for a fish tank. It will help provide the Bubble Eye Goldfish with an environment that resembles their natural habitat as closely as possible. Various decorations are available that you can use to make your tank more aesthetically pleasing.

A few plants in your fish tank may be beneficial for the health of your fish. Not only will they help improve the water quality, but they also provide your fish with a place to hide if they ever feel stressed. Live plants are always the best option, but artificial plants, plastic plants, or silk plants can also work in a pinch. Just make sure that they're not made of materials that might leech toxins into the water. Some of the best aquarium plants include Java Moss, Hornwort, Riccia fluitans, and Elodea.

Caves and rocks can provide your fish with a place to hide and feel safe. They also help create a more naturalistic environment for your fish to live in. However, make sure that the rocks you use are safe for aquarium use. Avoid anything with sharp edges, as they may damage your fish eyes, fins, or scales.

Gravel is a necessary component of any fish tank. It helps to keep the water clean and free of toxins. There are various types and colors of gravel available, so you can choose something that best suits your needs.

Note:

  • Always avoid using soap or chemicals when cleaning your tank, as they can be harmful to your fish.
  • Do not use any objects with a sharp edge in your fish tank, as they may damage the delicate Bubble Eye Goldfish.
  • Do not overcrowd the tank with plants, as bubble eyes goldfish have very delicate eyes and will be more prone to injury.
  • Make sure that the decoration used in the fish tanks is free of toxins that might harm the fish.
  • Do not place a lot of unnecessary objects in your fish's tank, as this could cause them stress and limit their swimming space.
  • Follow a weekly water change to ensure optimal water quality, which is important for the health of your fish.

Bubble Eye Goldfish Tank Mates 

It may be difficult to find compatible tank mates for Bubble Eye Goldfish. There are a number of causes for this. To begin with, their eye sacs are extremely delicate and can quickly be damaged by hazardous or outgoing fish.

Secondly, their slow swimming makes it difficult for them to eat regularly. Fast-swimming fish will compete for food, leaving nothing left for the Bubble Eye Goldfish.

A Bubble Eye Goldfish thrive in groups of their own kind. However, if you want to start a tank with fish from different species, choose fish that have the same handicap as the Bubble Eye Goldfish. Telescope Goldfish, Celestial eye Goldfish, Black Moors, and Lionhead Goldfish are some great options.

Bubble Eye Goldfish Diet 

Bubble Eye Goldfish are omnivorous and will eat both plant and meaty food. A good diet for a Bubble Eye Goldfish should consist of a balanced mixture of proteins, fats, vitamins, and minerals.

A diet rich in plant matter will help ensure that the fish stays well-nourished and healthy. Common foods for Bubble Eye Goldfish include peas, spinach, lettuce, algae wafers, and specialized goldfish food pellets.

In order to maintain optimal health, it is important to make sure that your fish are getting enough protein in their diet. Protein can be found in live foods such as live brine shrimp, earthworms, and krill. You can even provide them with frozen food or freeze-dried food.

Vitamins and minerals are essential for the proper development and function of all systems in the fish's body. A lack of these nutrients can lead to a variety of health problems. Make sure to include foods such as spirulina, and brine shrimp in your fish's diet.

Flake food and pellets are a great way to make sure your fish are getting all the nutrients they need in an easy and convenient way. Be sure to include both sinking and floating pellets in the tank so that all fish have access to food.

When to Feed Your Bubble Eye Goldfish 

In order to keep your fish healthy, it is important to understand how much food they need and how often they need to eat. Generally speaking, the amount of food you should give them will depend on the size and age of your fish. It is very important to provide the younger fish with smaller portions more frequently as they are still growing. But an adult fish must be fed only 2-3 times per day as their metabolism slows down.

When feeding your fish, keep in mind that they can easily over-eat and become bloated. In order to avoid this, always make sure that there are no more pellets or flakes left in the tank after you have fed them.

If you notice that your fish appear to be overfeeding or not eating their food, it could be a sign of a health problem. Check for signs of stress, such as hiding at the bottom of the tank or sleeping more than usual. It is also possible that they are not hungry due to poor water quality. Be sure to test your water regularly and make any necessary changes in order to maintain healthy conditions for your fish.

Bubble Eye Goldfish Diseases

Bubble Eye Goldfish like any other fish are prone to a number of illnesses that can affect different parts of their body. Some common diseases include:

  • Fin Rot: This disease is caused by poor water quality and can lead to infection in the fins and eventually the entire body. Symptoms include clamped fins, loss of appetite, and a whitish or bloody appearance on the skin.
  • Ichthyophthirius (Ich): This disease is also caused by poor water quality, and is characterized by white spots on the body. These spots will spread, causing excessive scratching and eventually death if left untreated.
  • Dropsy: This disease is caused by poor water quality or infection in other organs such as the lungs or liver. Swollen scales are a common symptom of this illness, as well as lethargy and loss of appetite.
  • Swim Bladder Disease: This disease is caused by constipation and leads to difficulty swimming properly. Swollen abdomens and curved spines are common symptoms of a swim bladder disorder.
  • Skin Flukes: This disease is caused by parasites, and leads to irritation and itchiness around the eyes or gills. It can also lead to inflammation in other areas of the body.
  • Popeye: This disease is caused by poor water quality and leads to bulging eyes. Other symptoms include cloudy eyes and a loss of appetite.

Prevention 

Prevention is always the best medicine, and there are a few things you can do to keep your fish healthy and free from disease, they are:

  • Keep your water clean and at the right temperature (Goldfish can only survive in temperatures between 65°F and 72°F) as these species have a high risk of infection.
  • Feed them high-quality food that will provide all the nutrients they need.
  • Do partial water changes weekly to make sure that your fish are not being exposed to toxins or bacteria.
  • Quarantine new fish or plants that you add to your tank, as they could be carrying diseases.
  • Do not overcrowd your tank, as this can lead to stress and illness in your fish.
  • Make sure not to overfeed your fish, as this can lead to bloating and other health problems.
  • Monitor your fish for signs of stress and poor health, and talk to your local pet store or veterinarian if you notice anything unusual.

Bubble Eye Goldfish Breeding 

Bubble Eye Goldfish breeding is not a difficult task. However, there are several factors that you will need to consider if you want to have a high chance of success while breeding these types of goldfish.

If you are a novice fish keeper, it is best to consult with a more experienced fish keeper or breeder before attempting to breed Bubble Eye Goldfish. However, if you are confident in your ability to breed your fish, these are some important considerations:

  • Select the breeding pairs: To increase the chances of success, it is best to start with a group of young fish. This will give you a greater chance of finding pairs that are compatible. It is also important to make sure that the pairs are of similar size and age. 2-year-old fish are typically the best age to start breeding. Make sure that the pairs are healthy and free of any diseases or parasites. This will help ensure that the breeding process goes smoothly and that the fry is healthy as well.
  • Conditioning the breeding pairs: It is important to condition the breeding pairs before starting the process. This means giving them a high-quality diet and making sure that they have plenty of space to swim. It is also important to make sure that the water quality in the tank is high. Slowly increase the temperature in the tank to stimulate breeding.
  • Breeding Tank Setup: It is important to have a separate breeding tank set up before starting the breeding process. This will help ensure that the fry is protected from the parents and other fish in the tank. The breeding tank should be at least 10 gallons in size. It should also have a filter and a heater to maintain the correct water temperature. To begin the creation process, heat the breeding tank to approximately 60 degrees Fahrenheit. Every day, gradually raise the temperature by 3 degrees. The males will start chasing females at 68 to 74 degrees Fahrenheit.
  • Spawning: When all of these factors have been taken into consideration, you are ready to start the breeding process. It is important to be patient when breeding Bubble Eye Goldfish as it can sometimes take several weeks to produce their first eggs. The male chases the female around the tank in the spawning process. He will nudge her side with his snout to pique her interest and encourage her to release eggs. She will then gyrate, allowing eggs to fall out of her body. The male will quickly fertilize them after that.
  • Bubble Eye Goldfish fry: Once the eggs have been fertilized, it is important to remove the parents from the breeding tank. The fry will hatch after 4 to 7 days. They will live off their yolk sac for the first day or so. After that, you will need to begin providing them with good quality fry food which you can get from any fish stores. It is always best to grind up the baby fish food to a very fine powder so that the fry can easily digest it. You will need to continue feeding them several times a day until they are large enough to eat regular fish food.
