Guppy – unpretentious fish, with their content under the force to cope even novice aquarium lovers. Females cannot boast a bright color, but the males shine with all the colors of the rainbow, especially the beautiful guppy’s tail.
Guppies are viviparous fishes, so by the time of birth the fry are already fully formed and can eat infusoria, small food and swim on their own.
Guppies breed even in small aquariums, the gestation period of fish is about 30-40 days, depending on the conditions of detention. Pregnant females are deposited in a separate jar or aquarium with a temperature of 22-26 degrees.
The time of jigging can be determined by the darkening of the eggs and the rounded abdomen. Since females are prone to eating offspring, floating vegetation is placed in an aquarium.
If the fish cannot give birth, this process is stimulated by adding some fresh water and, by raising the temperature by 2-4 degrees, sometimes the male is hooked.
Guppy is the natural habitat of the United States, southern and central America. Fish keep flocks in fresh water or the mouths of rivers or lagoons. In captivity usually live 3-4 years.
The main color of guppy is blue, gray, cream, silver or white. Additional blotches can be black, red, yellow, green, blue, or metallic.
Guppy fins are small, rounded, while absolutely colorless.
As for size, males have a length of 1.5-4 cm, pedigree representatives are distinguished by long fins and variegated coloration. The males also have an anal fin, which is called gonopodium.
Female guppies are larger, reach a length of 7 cm, they do not have an anal fin, but the calf is visible. Many individuals have a natural gray color, and on the body there are scales in the form of a rhombic grid.
Fishes of this species were named after the priest and scientist Robert Guppy, a native of England. He was collecting plants and soil samples on the island of Trinidad, when he accidentally saw brightly colored small fish in one of the reservoirs.
Looking closely, he noted that they do not lay eggs, like most individuals, and immediately give birth to fry. In 1886, he returned home and spoke to the Royal Society with a report on the found tropical viviparous fishes.
However, they did not believe that such small fish could be viviparous, and as it turned out in vain, soon there were hundreds of guppies in the aquariums of the British Museum, which multiplied from the specimens brought by scientists.
Strangely enough, for the first time, guppies were brought to Europe much earlier, in 1859, ichthyologist from Germany, Wilhelm Peters, found an instance of guppy in one of the collections; In 1861, scientists from Spain Filippi found the same fish in the collection sent from Barbados.
The director of the British Museum did not seem to be aware of these discoveries, so he named Robert Guppy a pioneer and assigned the name Girardinus guppyi to a new aquarium species.
For several decades, breeders have bred 13 species of guppies, which differ in size and shape of the tail fin. Also, 8 species of traditional guppy coloring were bred.
Based on 2 main features, there are about 100 combinations of background color and fish forms of this species in the world.
For keeping representatives of the guppy family, an aquarium of almost any capacity will be suitable. One pair of fish can be settled even in a three-liter jar, however, in such a quantity of water, representatives of this species cannot achieve large sizes. On average, for each fish should be 1.5-2 liters of water.
The main factor for content and breeding is the quality of water, the three most important parameters are hardness, acidity and, of course, purity.
The smaller the volume of the aquarium, the faster the products of vital activity of the guppy pollute the water, in such an environment the pathogens develop faster, which can cause illness and even death of the inhabitants. It is advisable to keep guppies in spacious aquariums, regularly change the water.
The most acceptable plant for a guppy aquarium is an Indian fern, which can be called a unique live filter. Hydrogen indicator of water should be about 7, equip the “dwelling” of fish with good filtration.
Remember, the PH value is not constant, it depends on the lighting, the number of inhabitants of the aquarium, the presence of plants.
Water hardness is a parameter that should not exceed 4-10 ° dH. Excessively hard or distilled water is not suitable for keeping guppies. Do not forget about the lighting, on average the daylight hours should last 10-12 hours, it is recommended that the sun be on the aquarium for some time.
It is possible to determine if there is enough light with the help of the Indian fern: if it grows well and has a healthy green color, then the fish have enough light. If the leaves are brown, and the fern grows sluggish, it means that there is a clear lack of light, when there is an excess of light, the water begins to “bloom” and the fern is covered with algae. Soil for the aquarium should not be very dense, choose the middle fraction.
It should be washed at least once every six months, first checking for solubility.
Guppies are practically omnivorous fish, in addition to ciliates and cyclops, they willingly eat dry food, finely chopped meat, squid fillets, cereals. Fish should be predominant in the diet, which should preferably be alternated regularly: daphnia, small bloodworm, Artemia, sometimes you can give pipe makers, moin or coretera.
In a small number of inhabitants of the aquarium and give vegetable feed, you can feed the compound feed. The main thing – do not add too much food, otherwise part of it will settle on the bottom and pollute the aquarium, regularly change the water.
For keeping guppies bred in captivity, you will need an aquarium with a large number of plants. These fish are quite peaceful and will perfectly coexist with non-aggressive fish.
It is impossible to choose fast-swimming fish as companions, for example, barbs, they are very active and can catch hold of the fins and beautiful tails of male guppies and simply tear them away.
Guppies swim in the upper and middle layers of the water, so that it is quite possible to share with them peaceful schooling fishes of the family of haracin, corridors, neons, zebrafish, pizza. Guppies and those fish that prefer the lower layers of water for living will also not interfere.
These are small fishes, small catfish. From sharing content with cichlids is better to refuse.
• For the birth of the offspring of this little fish, sometimes even a glass of water is enough.
• In the second half of the 19th century, Europeans noted that on one of the islands in the reservoirs of which guppies were found, local people did not suffer from malaria. And in the neighboring continents, where these fish were not found, the disease raged.
After the fish were settled in the waters of the West Indies and some regions of America, the incidence of malaria decreased.
• Experiments on guppy crossing have helped genetic scientists understand the laws of heredity.
• Guppies are very sensitive to the environment, so they were tested for the degree of wastewater treatment, the effect of chemicals.
• Guppies are the first aquarium fish that even managed to visit space, aboard the Salyut-5 orbital station.
Guppies are among the ten most unpretentious and popular aquarium fish.
You can buy guppies in a specialized kennel. The price of Guppy fry can be found on the bulletin board.
