Live-bearing aquarium fish

To viviparous fish include a large group of fish that live in fresh and salted waters of South America. The main difference between these fish from the others because the eggs fertilized inside the female’s body and are born fully formed fry, ready to eat. The maturation of eggs occurs on average during 22-50 days, depending on the variety.

Guppy.

the guppies smack the most undemanding aquarium viviparous fishes are guppies, that’s why they advise you to start the novice aquarist. These fish have a calm disposition, friendly, beautiful, and at the same time they do not need thorough maintenance, the strict temperature control. Its name was given by name English botany Guppies, who in the mid-19th century brought them to Europe from the journeys together with lots of plants from the tropics. Among the fish were bright with males scattered throughout the body stripes and spots of various colors, and gray, nondescript, but large females. So took root and became widespread in the aquariums of the Europeans the inhabitants of Venezuela, Guiana, Barbados and Trinidad Islands.
The fry of guppies are born in a thin caviar membrane, through which immediately float to the surface of the water, whose temperature should be between +22° to +24°C. on the first day they are completely independent. Moreover, they have to hide in thickets of aquatic plants, not to become dinner for their parents.
Better to feed guppies live food (Daphnia, Cyclops), but also dry food for aquarium fish, they do not disdain. Many manufacturers produce special food developed specifically for guppies.
Clockarium guppies guppies are quite small: no more than three years. Therefore, Mature early. Six-month the fry are able to produce offspring. To be complete, we must be prepared to select some of the most healthy, active and beautiful pairs to settle into the aquarium with water heated to +25°C and to feed only live food. When it is rounded abdomen of the females popolnyat and it will be a weak dark spot is darker than it is, the sooner will the fry – they must be deposited into another aquarium, or even in three-liter jar. Their offspring, the female guppy can carry from 25 days to two months. This affects a wide range of food that she gets, and water temperature.
Under natural conditions rivers – tropical – guppies greatly benefit by destroying the larvae of the malarial mosquito.

Spotted platies (platy)Platyptilia.

These colorful, easily changes the color of the fish has received speaking name, giving them a description, because the word “plate” translates as “broad” and “platies” – as “volatile”. Really neat, but slightly extended the body of fish has a whole range of various colour combinations and shades.
If it is not possible to install a large aquarium, and have a lot of bright fish I want, platyptilia is the most suitable option. After all, these fish, in natural conditions, living on the coasts of Guatemala and Mexico, very hardy, eat with appetite and dry food, and living can cost a small living space. In addition, you can engage in the crossing-spotted mirror, dotted, black plyatipetsily and get new varieties of fish.
To breed platyptilia not dangerous, unlike guppies. The temperature regime they need to maintain a standard for all viviparous fish.

Macroeconomy.

Unassuming and prolific, too, the inhabitants of the waters of Honduras, Guatemala. Mexico. Males of these fish have a tail fin ornaments in the shape of a sword, for which he received its name. In addition to the sword with emerald scales derived by crossing fish of all colors with different spots, stripes and simple plain.
For example, the Montezuma swordtail Golden cream color with a brown stripe on the side and small brown dots. Montezuma differ from their counterparts of lower fertility.
Unfortunately, the sword is also not averse to eat the offspring, so during spawning, it is necessary to set up an aquarium so that the newly hatched fry fall to the bottom through a narrow slit, and the adults couldn’t get to the newborn.

Girardinus.

His name these natives of South America have a duty to the traveler and scientist Gerard. These scrappy fish are also unpretentious neither to food nor to the size of the aquarium. The only thing that they do not tolerate, direct sunlight and overheating of the water. But like dark places, in the reservoirs of his native Argentina that are easy to recreate by planting aquatic plants, and can withstand relatively cool water (up to +15°C). However, because of such features of girardinus difficult to maintain in an aquarium with other fish.
An interesting ability of girardinus: in the cool water or from fright the black spots on their body immediately become pale.

Formsoverdata.

This cream-yellow three-quarter-inch fish with big eyes, along the body which is a dark band, in turn, intersecting the transverse stripes at an equal distance from each other. Got to our homes from reservoirs in South-Eastern America. The aquarium with the recommended Formosa densely planted plants, because it’s her favorite food and at the same time refuge for tiny fry.
Formosa not only does not cause problems in the contents and decorate the aquarium, but also extremely useful for him because is a wonderful nurse. She collects plants, the microorganisms on which it feeds, and at the same time and carefully cleans the plants, removing them from the raids.

Mollies.

Molinaseca this whimsical fish can be taken after the experience with undemanding guppy, gangrene, swordsmen and plyatipetsili th. Two common species of mollies – mollies and the mollies velifera latipinna.
Mollies of velifer inhabits salt and fresh waters of Central and North America. Looks like a swordtail, but male mollies of velifera has a high dorsal fin.
Mollies of latipinna in vivo are grey in the dark spots of color. The older the fish, the darker its color. For procreation aquarists always try to take dark individuals to get offspring with black, like velvet, color. However, there is no guarantee that it will be necessarily black. Often appear grey and the fry, which, incidentally, is much larger and is growing faster than the black fry.
Young females hatched fry 40-50 days and bring them from twenty to thirty pieces, and older females – even up to a hundred pieces.
As a result of crossing velifera mollies with mollies, latipinna turned parusovaya mollies. Males of this species mollies to the second year of life acquire a beautiful black outfit, and females have a silvery-gray color with scattered black specks all over the body.
The complexity of caring for mollies is that to feel fresh, frisky, not to lose appetite they can only at water temperatures below 24°C and above +26°C. to Maintain a constant optimum temperature of the water in the aquarium conveniently using the heater with termoregulirovanija.

Feeding of herbivorous malinese need special dry food, which includes vitamin E, dried vegetable salad and seaweed with niccacci, although occasionally you can feed, especially young fish, dried Daphnia, live food (Cyclops, ankaramy).
Water for the aquarium with the mollies need a little salt in a tablespoon of salt to eight buckets of water. The height of the aquarium should ideally not exceed 40 centimeters, also need to support in it low level of water.
The offspring of the mollies are very delicate and often die. To minimize losses, you need to choose for reproduction a pair of healthy, strong, large individuals. A few days before we are expecting the female needs to be deposited into a separate aquarium, planted in advance. If too late to resettlement, the fry are born weak and often die. They appear to light with yolk sacs, from which they obtain food for several days. Not suitable for mollies as food Tubifex, irritating the digestive tract of the fish, causing them to lose weight and soon die.
