Characteristics and Care of the Blistering Eye

The aquilepus is a goldfish that has a dorsal finless feature found in the Ranchu lineage, and has a blister-like pouch on the lower part of the eye (around the cheek), which causes the black eye, which is usually attached horizontally, to point upward. In this article, I would like to explain in detail the characteristics of the aquatic eye and how to keep it.

What is a blistering eye?

The aquarium eye is a goldfish without the dorsal fin seen in the Ranchu lineage, and has a blister-shaped pouch under the eye (around the cheek) that causes the black eye, which is usually attached horizontally, to point upward.Its charming and unusual appearance has made it, along with the apex eye, a favorite breed throughout the world. The pouch of the blister eye is an enormous amount of only the cornea of the eyeball, and the pouch contains lymphatic fluid.

The Origin of the Blistering Eye

The Shuihougane is a variety that was created during the Qing Dynasty in China as a result of a mutation of the Dekomegane. It is highly likely that the apex eye was also born at the same time.At this point, we do not know much about the details of where and when the shui baogan originated during the Qing dynasty. Because it had long been favored by the upper classes (ruling class) of the court, it was not known to the general public as being outside the gates. Later, after the new system (royal court) was established, it became widely known to the general public, and the circumstances of its birth and other details are still a mystery. It first became known in Japan around 1958. When it first arrived in Japan, it looked exactly like a goldfish called the Hama-tou-yui (哈蟆頭魚), so in Japan it was called the Hama-tou (哈蟆頭魚). The Hama-tou-yui is a goldfish characterized by a slightly smaller pouch and more fleshy flesh than the Suifo-eye.

How to Enjoy the Blistering Eye

The best way to enjoy the aquatic eye is the characteristic pouch attached to the lower part of the eye. If you want to enjoy it, I recommend viewing it from the top in a bowl or the like (top view) rather than from the side in an aquarium (side view). By viewing it from above, the balance of the pouches on the left and right sides and the sight of the eye foam with the pouches swinging while it swims will give you an indescribable feeling.You can maximize the enjoyment of the unique appearance and swimming form that cannot be seen in other goldfish. Also, the black eyes, which have turned upward due to the pouch, can be appreciated by looking at them from the top, allowing you to enjoy the sensation of having eyes on the goldfish. When viewed from the side, you can see the frontal view of the eye of the aquatic bubble, and enjoy the cute appearance of the pouch on both sides.

Points to keep in mind when mixing swimmers

When mixing goldfish with other goldfish and other species, there is sometimes uncertainty as to what species is good and what species is not. First,There is no general prohibition against this or that when mixing goldfish with other species.Therefore, depending on the personality and environment of the goldfish you keep, even species that are said to be bad for each other may get along well with each other. However, there is also the matter of compatibility between goldfish. If you put incompatible goldfish together, there is a high possibility that they will fight or that only one of them will monopolize the food. However, as explained in the beginning, there is no prohibition for goldfish, so if you want to mix them, it may be OK to do so. Now, let us explain which goldfish are compatible with Japanese goldfish and which are not.

Compatible goldfish

Goldfish that are most compatible with the aquarium eye are Ranchu-type goldfish, such as Ranchu and Edonishiki.The aquarium eye variety has pouches on either side that could shrivel up if pecked, so a Ranchu-type goldfish, which is not a good swimmer, has less risk of being chased and pecked.

Incompatible goldfish

Goldfish that are incompatible with the aquarium eye are Japanese goldfish, such as wakin (Japanese goldfish) and comets.Many Japanese goldfish are agile and grow large in a short period of time. If they are mixed with goldfish of the Japanese goldfish type, it is necessary to carefully observe whether the aquarium eyes are being chased or pecked at by Japanese goldfish or other goldfish of the Japanese goldfish type.

What to look for when keeping a blister eye

In a blistered eye, the cornea of the eye has an enormous pouch, but the pouch can be ruptured by something trivial. Even if the pouch is torn, if it is a small scratch, it will repair itself and swell up again. However, the possibility of the pouch returning to its original size is extremely small. In most cases, it will be smaller than its original size. This can lead to an imbalance between the left and right sides of the body, which may reduce the evaluation of the appearance. In addition, if the area has been torn many times or if the scar is large, it may not be repaired, and the area may become deflated.If this happens, the aquarium will lose its pouch, which is the most important feature of the aquarium. In order to prevent this, it is important to avoid placing ornaments with sharp edges or objects with sharp edges in the aquarium (pot, etc.) that contains the squids, and to be most careful when moving the squids to a bucket or tub for water changes. When moving the eye foam to a bucket or tub, many people use a net, but the net often gets caught in the eye foam bag and tears it without their knowledge, so please ask them to be extremely careful when moving the eye foam. However, please be assured that the rupture of the pouch of the blister eye does not mean that the eye will die immediately, but only that the greatest feature of the blister eye will be lost.
