Velife Molliesia: detailed manual for content and reproduction

Velifera Pecilya is the most beautiful and attractive representative of the viviparous or gambusian family. For the first time, these fish were found on the Yucatan Peninsula and the first shipments to Europe went in 1913 and since then the fish has been qualified as the Woliffer Mollies.

In the course of subsequent revisions, the fish were attributed to the genus of petsilians.

Velifera’s Molinesia is the largest fish in the family, which is 20 centimeters in length in natural conditions. Under aquarium conditions, the size of the fish is much more modest, females grow no more than 15 centimeters in length, males – 12.

Natural coloring in males is simply gorgeous: the main color is silver-gray with a scattering of shimmering mother-of-pearl specks. The dorsal fin has a reddish edging and its length is about the same as the length of the fish itself.

That is why a hydrobiont is often called a flag plaza.

The color of the females is much more modest, and the size is slightly larger and the structure of the body is full in the abdomen. Unlike males, females do not have dorsal fins in the form of a sail.

The body has an elongated shape and slightly flattened on the sides. The tail fin is round if the fish is caught in nature, and the forked fish if the fish is obtained by breeding. In lyretail fish, tail fin rays can either connect or diverge at a 90 degree angle.

The first option is considered decorative, because it gives the body of the fish logical completeness, which allows to reflect the range of colors.

Fish with a rounded tail look not so slim and beautiful. However, for unknown reasons, many aquarists prefer round-headed fish, believing that these fish grow larger than the lyre-tailed congeners.

In addition, puberty in these fish occurs a little earlier.

The Velifers are famous for their excellent sight and smell. Fish react quickly to any sound stimulus and sudden movements of the aquarist, which is located at a distance of several meters from the aquarium. Of course, mollies are far inferior to cichlids intellectually and intelligently, but if you compare this fish with other representatives of the pets, they are Einsteins.

Arguing about velifiers, not to recall the relatives of Poecilia latipinna would be sacrilege. The most beautiful and popular types of high-grade pezily were obtained as a result of crossing two types.

Under natural conditions, the placidum latex has a relatively larger habitat than the valifers: in addition to the Central American reservoirs, the Latipins occur in the reservoirs of the eastern United States. When compared with sailing mollies, the Latipins are smaller. Under natural conditions, females grow no more than 12 centimeters in length, males – no more than 10.

In aquarium conditions, the standard length of a fish is 8 to 10 centimeters.

Indiscriminate selection has led to the fact that it is no longer possible to establish the species of a particular fish, but to accurately classify the aquatic organisms by color form in general from the realm of fantasy. The first attempts at the hybridization of the Latipins and Velifers began in the natural conditions of their habitat.

As a result, the work of breeders has led to the appearance of a large number of different color variations, which also differ in the shape of the body and the pattern on the body.

In nature, the petsilium live in fresh and brackish waters. In addition, ichthyologists were able to find Velifer and Latipin in seawater, and the marine variant of the chilli is distinguished by its larger size and bright color, which freshwater forms do not have.

Purebred Velifers have several stable color forms: marble, albino and natural. The first two were obtained as a result of breeding surveys by ichthyologists, and other fish of this family did not participate during breeding.

Albinous forms have a yellow-orange color with light blue tint of scales and red eyes. Among albinos there is also intraspecific selection, due to which some individuals can have a body color like light yellow, bright orange and even red.

Marble platies are called snowflakes due to the white color of the body and all fins, except for the dorsal and caudal, which have a bluish tint.

Sometimes the albino form is attributed to the color variation of the latexes. However, this is not entirely correct, because the marble petsyli are derived from the intraspecific selection of the natural form.

Of course, except for the size, the snowflakes are very similar to the fish of the classical natural form, but it so happened that all the breeding forms of fish are smaller, as the selection is carried out in small-sized aquariums.

Neither in the aquarium, nor in nature, the partitions Velifers do not form strong pairs. In aquarium conditions, fish try to keep a small flock and leave the community only in those cases, if you need to care for the female.

A large male will always claim a leading role in the pack. In the process of clarifying the relationship of serious skirmishes do not happen and the fins remain intact. To create healthy competition in an aquarium, it is recommended to keep the same number of males and females.

In addition, such a flock will look more impressive than a group of fish in which most females.

As neighbors to the delights, any peace-loving fish, preferably live beetles (black mollies, swordtails, guppies, other species,) can be hooked up by coloring them. Because even the tricolor types of the pesil against the background of the gentle Gelfer look not quite appropriate.

Spawning in the pecily of the Velifera proceeds in a similar way, like other representatives of viviparous. After mating, one adult female can produce from 70 to 130 full fry no more than 10 millimeters long.

From the very first days the youngsters are ready for the harsh life of the aquarium.

The most optimal type of starter feed for fry is Nauplii Cyclops and Artemia. If we compare the Velifers with other pets and live-bears, they do not eat their children.

But, if you want to leave the future offspring safe and sound, as well as not to violate the regime of full feeding, it is advisable to transplant the young in the previously prepared aquarium. The hydrochemical parameters of the water in the tank should be the same as in the general aquarium, only the temperature of the water should be increased by a couple of weeks by a couple of weeks.

Young animals are grown up extremely simply: in order to get high-quality young, you need to feed well and each week replace about 80 – 100% of water with fresh water while ensuring high-quality filtration. Substitution should be done in compliance with all the rules of hygiene: siphon of soils, washing the filter and cleaning the compressor tubes from the bacterial film.

At the first stage of feeding the fry, brackish-water rotifer will be suitable, which will then need to be replaced with larger and more nutritious types of food. Instead of micro-feed, you can use chopped bloodworm or tubule. In the first month of life, the fry should be fed 4 to 6 times a day.

Feed the fry better in the most lighted areas of the aquarium.

Unfortunately, like many other species of fish, the juvenile chilias Velifer are growing unevenly and the strongest fish will be noticeable fairly quickly. If you want to use fish as producers, from the first days of life, defective juveniles should be discarded. The rate of development of fry depends on a number of factors: feeding and housing conditions, the effectiveness of hygienic measures.

In the most ideal scenario, puberty occurs at the age of six months + 1 – 2 months, that is, a little later than in other species of live beetles. However, the Velifers live longer, unlike other viviparous.

What do you need to grow a great helfer? First you need to get a large and spacious aquarium. In small banks, the fish do not develop well and do not reach the desired dimensions.

In addition, the productivity of fish suffers greatly and a large number of underdeveloped fry are born. It is also not possible to form a full-fledged group of producers, which will consist of 10 to 12 adult fish.

The minimum volume of the aquarium for such a quantity of fish should be 200 liters.

In order for the fish to develop normally, it is necessary to regularly monitor the condition of the aquarium water (weekly changes in the amount of 30% of the total). What is very important, fresh water should have such parameters as in the general aquarium.

As it turned out, the peptic ulifers are sensitive to a lack of calcium, because they are derived from water during gas exchange.

Hydrochemical parameters of water should be as follows:

  • Active medium reaction 7.0 – 8.8 pH;
  • Water hardness 8 – 25 degrees;
  • The water temperature is 22 – 24 degrees.

In order for the fish to be healthy, the water in the aquarium should be clean as a tear, only in this case the pets will enjoy the eye of the aquarist with the rampage of their coloring. In addition, the purity of the aquatic environment plays a key role in maintaining the health of all inhabitants of the aquarium, as well as their development. Accordingly, there should be a powerful filter in the aquarium, preferably an external one that is paired with a biofilter.

Quite well, it proved to be false when cleaning aquarium water when the contents of the gelifer.

We should also talk about the temperature regime in the aquarium. The overwhelming mass of specialists claims that 22 – 28 degrees is considered the optimal temperature range for cultivation. At high water temperatures, the fish begin to shrink and their color turns pale.

Kochetov recommended the maintenance of aquarium fish at the lower limit of permissible temperature, allowing the body of the inhabitants to get used to such a temperature regime.

However, when keeping fish at low temperatures, you need to be extremely careful, because if you violate other requirements for habitat conditions and biological equilibrium in an aquarium, fish may start to get sick massively. In addition, you should be perfectly aware that the water temperature of 22 degrees can lead to the fact that the vast majority of aquarium plants can stop the growth.

Experienced experts in velifera recommend keeping this fish at a salinity of 2 to 5 ppm. If you believe their beliefs, then the fish improves the performance and secretion of mucus skin. However, no one really knows how to do this in a home aquarium, if other fish and higher plants, often very demanding to their living conditions, live in it besides the wormifer.

What to do with the biofilter, which in salt water will not perform the tasks assigned to it? There is still no clear answer.

There is no definite and clear model for aquariums with helfer’s aquariums. A characteristic feature is the presence of dark soil from rounded particles.

Fish will look more effective if the background of the aquarium is black or dark blue. With regards to aquarium plants, it is better to opt for echinodorus of the Uruguayan group and aponogetonah.

These plants grow beautifully in conditions that love the Velifer, like frequent water changes to fresh. Of the cryptocoryne, the best suited cryptocoryne ponterium and Ivoryst, Wendt.

And Wendt can change the shape of their leaves, they will eventually become narrow. In addition, dwarf echinodorus species are excellent: tenellus and quadricostatus, which form a green carpet in the aquarium near the front wall of the aquarium.

From dlinnoshebelki perfect limnofila ambulia, Bacopa Caroline. But the cabomb and peristolistnik are no longer so suitable for keeping with these petillas in the same aquarium.

All the above plants love light and are actively involved in the biological purification of aquarium water. At the same time, it is known that the Petsiliev excrements are very useful for aquarium vegetation, because they quickly decompose, thus feeding ground microflora.
