The viviparous aquarium fish represent a huge group of fish that live in fresh and low-salt waters of South America. Their main difference is that the roe is fertilized inside the body of the female, due to which already formed fry are born that are able to feed on their own. In this case ripening takes place in 22-50 days.
Speaking about what viviparous aquarium fish are (photos are presented in this article), it is worth noting that the most unpretentious of them are guppies, so they should be bought by a novice aquarist. They have a very calm disposition, are beautiful, friendly, and they do not need regular care, as well as compliance with the temperature regime.
These viviparous aquarium fish got their name from botany Guppy. He brought them to Europe in the 19th century, along with several tropical plants from traveling to hot countries. Among the fish there were bright males with specks and stripes of various colors, as well as nondescript gray, but at the same time large females. Thus, in Europe, the inhabitants of Guiana, Venezuela, the Trinidad Islands and the Island of Barbados became widespread.
It is desirable to feed guppies with live food (in the form of cyclops, daphnia), although they do not refuse from dry food. Many companies produce special products for them.
These viviparous aquarium fish belong to the order kurtosuboobraznyh, the family of petsilievyh. Due to their color, they are incredibly popular with aquarists. In their coloring all the colors of the rainbow are presented. from crystal white with yellowish, pink or sky blue light to charcoal black and carmine red.
More than 20 genera and about 150 species of the family inhabit the tropical and subtropical waters of America. Pecilia is a small fish that has become one of the most popular due to its changeable and bright coloring. Due to this, every year aquarists see all its new variations, which appeared with the help of breeders.
These easily changing color, variegated viviparous aquarium fish, the names also have "speaking". The word "plyati" means "broad", whereas "petilia" means "changeable." In fact, a neat, slightly expanded body of a fish has a whole range of various shades and color combinations.
If there is no possibility to install a large aquarium, but you really want to have a lot of bright fish, the beach pets will be the best option. These viviparous aquarium fish living in natural conditions on the coasts of Mexico and Guatemala are incredibly hardy, eat any food with appetite, and can also do with a small space for a comfortable life. In addition, you can do the crossing of the mirror, spotted, black, point beaches of the specimens, thus obtaining their new varieties.
Fish for their offspring are not dangerous. For them, the temperature regime is necessary to maintain a standard, in which live-bearing live aquarium fish, whose species are presented in this article, live comfortably.
These natives of South America owe their name to the scientist and traveler Gerard. Girardinus unpretentious to food, as well as to the volume of the aquarium. They do not tolerate overheating of water and direct sunlight. Fish prefer dark places that can be easily recreated by planting special aquarium plants. Girardinus easily maintain cool water. Although, due to these peculiarities, the fish are difficult to maintain in one common aquarium with some other species.
One interesting thing is the ability of the gyrardinus: from fright or in cool water, the black spots located on their body instantly become pale.
The fish is a prolific and unassuming inhabitant of water bodies of Guatemala, Mexico, Honduras. Their males as a decoration have a tail fin in the form of a sword, for which they received their name. In addition to the sword bearers with bright emerald scales, the method of crossing derived varieties of all shades of the rainbow with all sorts of stripes and specks. For example, the montesum swordtail has a golden-cream color with small brown dots and a brown stripe located on its side.
It is worth noting that these fish are less fertile from their relatives. But the Sword-bearers are not against eating their offspring, therefore, during spawning, the aquarium should be arranged in such a way that the fry would fall to the bottom through a narrow slit, while the adults would not be able to get to the newborn.
It is a two-centimeter cream-yellow fish with large eyes, in which a dark thin stripe runs along the body, intersecting by transverse stripes located at the same distance from each other. She came to our homes from the rivers of Southeast America. It should be noted that the aquarium with formose should be planted heavily with plants, as this is its favorite food, as well as a refuge for its fry.
Formosa does not cause any problems in the content and adorns the entire aquarium, while it is extremely useful for him, as it is an excellent orderly. It collects microorganisms from plants, and feeds on them, while thoroughly cleaning all plants, removing deposits and dirt from them.
For this naughty fish, you can only be taken after the experience gained with the formos, guppies, beaches, and swordtails. The most common are two types of mollies. latipinna and valifer.
Velifer molliesia is found in fresh and saline water bodies of North and Central America. It resembles the outwardly swordtail, although the male fish has a fairly high dorsal fin.
But the latipins have a natural gray color in dark spots. The older the fish, the darker its color. Aquarists always try to select individuals of dark shades for procreation in order to get a brood with a black, as if velvet color. Although no one will give you the guarantee that it will turn out necessarily black. Quite often fry of gray shades appear, which, by the way, grow faster and much larger than black fishes.
Young females bear fry for about 40 days, bringing them to 20-30 pieces, while more adult females even bring up to 100 individuals.
Due to the crossing of the velifera with mollies of the latipine, the so-called sail molliesia was formed. In this species, males, by the 2nd year of life, acquire a beautiful black “outfit”, while females have a silver color with black specks scattered throughout their bodies.
Mollies fry often die because they are very tender. To reduce losses, it is necessary for procreation to choose pairs from large, healthy, strong individuals.
A couple of days before replenishment, the female must be transplanted into a separate aquarium, already planted with plants. If the relocation is late, the fry are born weak, while they often die. Fry are born with yolk sacs. It should be noted that from them they receive food for a few more days. Mollies are not suitable as food pipemaker, which irritates their digestive tract, due to which they quickly lose weight and soon die.
