In the world there are a huge variety of varieties of aquarium fish. All of them differ in some external features. But among them there is one rather funny fish, when you look at which a smile appears on your face by itself.
Goldfish without fin
A funny fish, whose name in Latin translates as “heavenly eye” refers to decorative aquarium fish. The first mention of this species appeared in the distant 1772. Several manuscripts were brought from China to Paris, telling of wonderful goldfish that do not have an upper fin and strike with their amazing eyes raised to the sky.
The appearance of these fish is described even in ancient legends. Legends say that the "heavenly eye" was bred in Buddhist monasteries. These fish, turning their eyes up, were able to look directly at God. They were revered, looked after by them, as one of the sacred animals. This type of goldfish is still very popular among the Chinese. As before, they live in artificial ponds at monasteries.
Selection result
Experts say that without the participation of humans, the origin of this type of fish would be impossible. They were bred in special conditions. The funniest fish in the world was hatched in special porcelain flasks that were denied full access to sunlight. The flasks had small openings at the top through which light penetrated the water. Therefore, in order to get at least a fraction of the solar energy, so necessary for life, the fish looked up. After some time, the offspring began to appear with such eyes constantly. And they began to be called upper-eyed.
Specifications
It seems to many that decorative aquarium fish must certainly be small in size. The funniest fish, the photo of which you see in this article, differs from its counterparts in pretty decent growth. The length of an adult reaches fifteen centimeters. She has a very short head and small nose. As we noted earlier, the fin above is completely absent. During the sale, experienced specialists will immediately identify the real superlative. If on the back of the fish there will be at least a slight hint of a fin or a strip along the body, then the price of such a goldfish will immediately drop dramatically.
The eyes of the fish are directed upward by the pupils. The size of the eyes is pretty impressive. They are bordered by dense connective tissue and skin. Sky Eye has a very beautiful tail cut in two. Verkhoglyad can boast of a magnificent tail, it is much more magnificent and larger than that of ordinary aquarium inhabitants.
Also, these fish have a decent life expectancy. There were cases when the upper eagles lived to be fifteen. The average age is 10-12 years.
Conditions of detention
The funniest fish on the planet can live in any environment. The main thing is that there should be a sufficient amount of free space. Buddhist monks kept such fish in artificial ponds at monasteries. Today, aquarists settle the "heavenly eye" in volumetric aquariums. According to experts, fifty to sixty liters of water should fall on one fish 13-15 centimeters long.
Due to the structure of the eyes and head, a funny fish has some problems with feeding. In the winter season, it is recommended to warm up the aquarium. Also, these fish quite often suffer from various bacterial diseases. It is better to limit their "communication" with other fish and keep in a separate aquarium.
Perhaps, to call the maintenance and cultivation of the "heavenly eye" simple and easy will not work. But many lovers of aquarium fish, especially gold ones, claim that these wonderful funny creatures are worth it.
