Bubble Eye Goldfish Best Care Guide

The modern assortment of aquarium fish is so diverse that it is already difficult to be surprised at something. But representatives of some modern breeds of goldfish have such an unusual appearance that to this day they cause an ambiguous reaction from many aquarists. Some consider them handsome, others find nothing attractive. Nevertheless, these breeds have not lost their popularity and often find their place in hobbyist aquariums. In our article, we will tell you about one of the most amazing goldfish – water eyes.

General information

Water eyes, or bubble eyes (Bubble Eye Goldfish) – short-bodied selective form of goldfish, a distinctive feature of which is the presence of two “bubbles” under the eyes, filled with lymphatic fluid. Fish are not immediately born with them, “bubbles” begin to appear only a few months after birth and are fully formed by the age of two.

Like many other breeds of goldfish, water eyes were bred in China, only wealthy people could keep them. In 1958, the first representatives were introduced to Japan, making them more accessible to hobbyists. Now it is not difficult to acquire bubbles, but it should be remembered that their content has certain difficulties associated with the presence of “bubbles”.

The main question that worries many is what will happen to the “bubbles” if they burst for some reason. There is no single answer to it. In one case, restoration does not take place, in the other, they appear again, but have a different shape and size. It should be noted that with trauma, the “bubbles” are often exposed to the penetration of various infections, and this often leads to the death of fish.

Appearance

Water-eyed goldfish have such an unusual appearance that they most often cause a smile. The body is round-ovoid, up to 18-20 cm long, so do not think that these fish are miniature, and do not try to keep them in small aquariums. The caudal fin is bifurcated, does not hang down, the dorsal fin is absent, the rest are poorly developed.

The eyes are large with inviting vesicles filled with lymph. In the most successful individuals, they reach almost a quarter of the body size. Eyes are very similar to stargazers , but their eyes are directed more forward than up.

The color of the fish is quite diverse. There are individuals of red, white, black, blue, chintz, white with scarlet bubbles, etc. Goldfish look most impressive when viewed from above.

Habitat

All modern breeds of goldfish, including water eyes, are obtained as a result of selection and are not found in wildlife. Yes, and “bubbles” would hardly contribute to the survival of such individuals. Therefore, they can only be found in home aquariums and decorative ponds.

Care and maintenance

As we have already noted, the size of the adult water eyes is quite impressive. Therefore, if you want to get this breed, you need to take care of an aquarium with a volume of 50 liters per individual.

The main feature of the content of bubbles and eyes is the correct selection of decorations. They should not have sharp edges on which the fish could injure their periocular vesicles. We must not forget that the water eyes have not lost the love of their ancestors for digging the soil, so it should also be smooth. For example, Tetra Active Substrate is great, which is round granules and baked clay making them lightweight and harmless.

Plants for decorating an aquarium are most often chosen artificial, because most of the living will be eaten or dug up. You can leave your choice only on species with rather hard leaves: anubias , cryptocorynes , ferns.

Water eyes have a good appetite, which means they have a serious biological load on the aquarium. It is therefore important that a performance filter, such as the Tetra EX Plus , is installed in the aquarium . You cannot do without good aeration, so feel free to install a Tetra APS compressor of a suitable power. But the thermostat is not a vital necessity, because water eyes are cold-water fish that feel great at a temperature of 18-22 ° C.

A prerequisite for keeping peepholes is a weekly water change – 20% of the volume of the aquarium. This will prevent the accumulation of toxic metabolic products. Simultaneously with the change, the soil siphon is also carried out.

Unfortunately, tap water in most cases is quite dangerous for the life of fish, because it contains compounds such as chlorine or heavy metals. Tetra Goldfish AquaSafe Conditioner will help you instantly get rid of them. He will also add beneficial vitamins and natural protective colloids to the water. The use of the drug will allow you to avoid the inconvenient procedure of settling water and make it safe for your pets.

Compatibility

A species aquarium is an ideal choice for keeping peepholes. This will help to avoid injury to the periocular “bubbles” by other types. If you still want to add variety, then it is best to choose neighbors from other short-bodied breeds of goldfish: stargazers , ranches , telescopes , etc.

Exclude content from predatory and any active species ( Barbus , Donaciinae ), which can easily damage the main pride of the bubble eye.

Feeding water peepholes

Proper feeding of water eyes must be given special attention to ensure a long and healthy life. The digestive system of goldfish is adapted to the digestion of predominantly plant foods, so it should make up the majority of the diet. Long-term feeding with live or frozen food often leads to disruptions in the digestive tract and the death of the fish.

Tetra offers a complete line of Tetra Goldfish food that has been designed with all of their nutritional needs in mind.

The high fiber content is very important for the proper digestion of the bladder and the eyes. The food is highly digestible, which reduces fish waste, which means the water in the aquarium stays cleaner for longer. You can choose the most convenient form for you – flakes, granules or chips.

Do not overfeed the peephole, therefore it is recommended to feed the food twice a day in small portions. Once a week, be sure to arrange a fasting day: do not feed the fish at all.

Reproduction and breeding

It is quite possible to get offspring of water eyes at home, although it is not always easy. Difficulties begin with the choice of producers, because their sexual dimorphism is not expressed at all.

Spawning must be done in a separate aquarium. A separator mesh is laid at the bottom, a few small-leaved plants (hornwort, Javanese moss) are thrown. The equipment will need a compressor and a heater. The temperature in the spawning grounds should be kept at the level of 24-26 ° С.

Before spawning, opposite-sex individuals are recommended to be transplanted for 2-3 weeks, and then combined in a spawning container. In this case, there should be two males per female. Then you can easily observe that how the males will chase the female counterparts and fertilize the eggs, which she will spawn.

The fertility of the fish can be up to 10 thousand eggs. The parental instinct of the eyelids is absent, therefore, after spawning, the producers are removed.

The incubation of eggs takes about 2 days, and after a few more days the fry are already capable of self-feeding. Periocular “bubbles” begin to appear 3-6 months after birth. And aquatic eyes reach puberty at the age of about a year.
