Bubble Eye Goldfish
The Bubble Eye is a variety of goldfish that seems to have originated in China. It is believed that this fish is a result of mutation in course of breeding across various generations. Its eyes are pointed towards the sky and have two large, fragile fluid sacs underneath them. The fish derives its name from these fluid sacs. Its unique appearance and the fact that it is found in a variety of colors, including red, chocolate, blue, white, calico, and black, make it one of the most sought-after species of aquarium fish.
Its Eyes Set it Apart
Coming back to the eyes of the Bubble Eye goldfish, they are perfectly normal when it is small. The fluid sacs only start developing when the fry becomes 3-months old. Usually, both these sacs are opaque, of the same color, and of uniform size. They are fragile, so this fish has to be kept away from sharp objects and other fierce fish. These eye sacs give the fish very poor eyesight. Due to these sacs, its head becomes heavy, as a result of which it wobbles slowly when it swims. The Bubble Eye cannot swim fast, as its eye sacs hinder its movement. Additionally, these sacs add to its weight and therefore, you often find it floating at the bottom of the tank. It is easily swept away in the direction of the current due to its heavy body and slow movement.
Other Features
The Bubble Eye has an egg-shaped body. It has an evenly curved back with metallic scales from head to tail. It is also characterized by its double tail and absence of a dorsal fin; the latter making it a little unstable. All the other fins―the ventral, anal, and pectoral―are paired. An adult Bubble Eye goldfish measures around 6 - 8 inches in length. It has an average lifespan of 5 - 6 years. If subjected to proper care, it can go on to live for even 10 years at times.
Bubble Eye as a Pet
Remember that this fish is considered very fragile due to those eye sacs. If any eye sac bursts, it will regrow, but its size will not be the same. Also, when a goldfish loses the sac, the eye is prone to infection, which, in turn, can cost the fish its life. So, extra attention and care is required, if you want a happy, healthy fish in your aquarium.
There are certain things that you are required to do and certain things that you should not forget, if you want your goldfish to live a long and healthy life.
  • The first thing that you need to do is fill up your aquarium with at least 10 gallons of water per goldfish. Don't reduce the water, as they need at least 8 gallons of water for proper growth and survival. The water should be kept at room temperature and should stand for at least 24 hours before you introduce the fish into it.
  • Set up an aquarium filter and heater in the tank and maintain the temperature between 60 ºF to 75 ºF.
  • Change half of the water weekly and maintain the pH level from 6.0 to 8.0.
  • Do not add any sharp aquarium decorations to the fish tank, as they may pierce the Bubble Eye's sacs and burst them. You can use live plants or silk plants to decorate your fish tank. Place a sponge over the filters to ensure that the eye sacs don't come in contact with them. It will not just keep the fish safe from injury, but also from infections that are likely to occur after the sacs break open.
  • The Bubble Eye goldfish is omnivorous in nature. It will eat pallet eggs and leafy vegetables, such as lettuce and spinach, as well as bloodworms and shrimp. You can introduce a food cone to feed the fish. Make it a point to hang the food cone at the same position every day.
  • The eyes of the Bubble Eye fish usually face upward. They cannot see anything that is below them. When you feed them, make sure that the fish can find the food easily in the water. In fact, don't feed them anything that will sink to the bottom.
  • Don't keep any other type of fish with the Bubble Eye. Other species may be aggressive in nature and may burst its eye sack, or even eat up all the food.
  • Its eye sacs become bigger and heavier with age. Hence, the fish tends to sink lower to the bottom of the tank. Ensure that they get enough food regularly, as their eyesight might deteriorate further due to aging. Also, clear the bottom of all the sharp objects.
  • If you want to take out your pet Bubble Eye, make it a point to support its head and the sacs with your hands, as they are filled with liquid.
  • Due to its peculiar body size and shape, it may suffer from swim-bladder problems.
If you are a beginner, you should refrain from keeping this variety as it requires a lot of care. If you have good experience with delicate aquarium species, you can go ahead and get a couple of Bubble Eyes, and turn your aquarium into a fish paradise! If they are properly cared for, they will start breeding once they turn 2-years old.
