What is the life expectancy of aquarium goldfish? It is difficult to answer this question unequivocally, since various conditions of the maintenance strongly influence the duration of their existence in aquariums. We can only talk about what measures need to be taken to ensure that their stay in a closed aquatic system is more comfortable and durable.
Goldfish: who she is and where she came from
Perhaps this is one of the oldest representatives of a large family of carp, which they taught to live at home. There is every reason to believe that this happened a long time ago in China, where court breeders began to cross different representatives of silver carp and breed them in imperial ponds. And so the golden fish appeared in several varieties: the dragon’s eye, che, veins (vualehvostka), wakin, dzhikin.
In such almost natural conditions, decorative crucians lived for quite a long time. up to 20-25 years, and their weight reached 4-5 kilograms.
At the beginning of the 16th century, ornamental fish came to Japan, and another 100 years later. to Europe. In the middle of the 19th century, it reached America.
Interesting fact: for a long time, the Europeans believed that the golden Chinese woman did not eat feed at all and only drink water. As a result: 2-3 months of a similar hunger strike, and Karasik died.
Only after many years did the European owners of these beautiful creatures learn to maintain them (to the delight of the fish themselves).
However, since the late Middle Ages about the goldfish went bad rumor that their age is quite short. This is a misconception.
At present, the habits, character and condition of the fish organism of golden crucians are very well studied. There is a whole set of recommendations for the maintenance of fish, allowing them to extend their existence at home.
Optimum conditions for a decorative goldfish
Of course, there are no strict regulated rules for its content. We can only talk about some recommendations based on the vast centuries-old experience of aquarists of the whole world on the breeding of goldfish in captivity.
They belong to the cold-water, the fish feel great at normal room temperature. Even a slight heating of the aquatic environment is extremely poorly tolerated.
A few words about feeding. Crucians, as you know, are very voracious and almost omnivorous. And since a goldfish is a decorative crucian, it will eat as much as there will be food available. Feeding is frequent and abundant. a high probability of overeating, which will affect the duration of fish life is extremely negative. In addition, it must be remembered that animals eat well some aquatic vegetation.
Conditions of detention. Goldfish need space, so the aquarium should not be overcrowded. It should be remembered that it was originally a pond fish, accustomed to frolic in the water column.
Water parameters. This animal leaves behind a lot of waste, and the water loves clean and saturated with oxygen. Therefore, good filtration (especially mechanical) and aeration are extremely important.
General rules. So, summing up some information about the features of the content, we can formulate a few rules, the observance of which will prolong the life of goldfish for a long time:
- With a content of 3-4 individuals the required volume of the aquarium is 150-200 liters.
- Existence of the powerful external filter and the compressor for aeration of water.
- Feeding a variety of foods (vegetable, dry feed, worms) no more than 1-2 times a day. One day a week. unloading.
- Mandatory presence in the aquarium aquatic plants.
- Weekly water change at least of the total volume.
As a rule, compliance with these recommendations has a beneficial effect on the life of bright golden beauties. Unless, of course, in the aquarium is not brought infection.
It is noticed that the "pedigree" fish have more gentle health, and their life expectancy is much shorter. Zolotushka, genetically closest to its ancestors, is more likely to live a long life. Thus, long-bodied breeds, such as the common goldfish and comet, are better health than veil tails, telescopes, orads, etc.
It so happened that it was in England that there were goldfish that lived for 30, 40 and even more years! Perhaps, somewhere else there are the same long-lived women, but it was the English women who became famous.
So, in 1999, at the age of 44, she died. fish named Tish (male). Family Hand from the county of North. Yorkshire, where Tish lived for several decades in a small aquarium, was grieved by his death; he was literally a member of the family. Gordon and Hilda Hand buried him in the shade of the trees in his plot: Tish didn’t like the hot sunshine.
And in the Wright family a pair of goldfish named Splish and Splash lived more than 30 years. At one time, the head of the family Richard Wright told that for his pets, which he started when he was young, no special conditions were created: a 40-liter aquarium, room temperature water, no direct sunlight and feeding once a day with specialized food.
10 years ago the great interest of the media caused the message of death from old age goldfish named goldie, which was kept at home in Devon Tom and Pauline Evans. Goldie was the 46th year! The owners sadly buried him in a secluded corner of his garden.
How many live aquarium goldfish? Definitely not tell, 10 or 40 years Perhaps this is a matter of chance. We can only hope that the creation of optimal conditions for the golden beauty will increase her chances of a long life!
