Composing the original and bright ensemble of fish in the aquarium, anyone will pay attention to the black as coals, fish with a cheerful and active character. These are mollies, one of the most popular aquarium inhabitants for many years.
Possessing such an original appearance, they are characterized by several advantages:
- often and easily multiply;
- compatible with many species of fish, with some even crossed.
Today there are quite a few options for Molly (such a soft and pretty short name). In household aquariums are most in demand:
- sphenops, (Mollinesia sphenops, Poecilia sphenops) (evenly black colored individuals with beautifully curved fins);
- Velifera (the exact opposite of the generally accepted idea of the blackness of mollies and the most appropriate to its natural congener);
- Latipina (similar to the blender, but a slightly smaller version).
It is noteworthy that the naturally occurring mollies have a yellow-gray color and a white belly, live in Mexico and America, and prefer coastal zones of rivers, especially with brackish water. Often you can find individuals, wildly sprinkled with blue-black or blue-gray specks.
They have a particularly playful character and need for clean fresh water.
One of the bright features of a molly can be a tail, like a lyre. Made as if according to a scheme with mathematical accuracy, it is so original that it served as a pretext for creating a series of original stories.
The shape of the tail is not tied to the form and color. Lyrebird can be black, two-colored, speckled, yellow and other variants.
Contrary to the opinion that this aquarium fish is an unpretentious and primitive creature, it is quite demanding and principled. It will be fun and active only in water with such characteristics:
- temperature 25-27o;
- acidity in the range of 7.2-8.5;
- water hardness from 10 to 35.
But that’s not all. Molly love bright lighting, the duration of the “light day” should not be less than 12 hours.
At the same time, she likes to hide, for which she prefers thick and bright algae bushes, which also serve as shelter for fry. The fish is very demanding for the freshness of water, its aeration and purification.
It is noteworthy that if the conditions of detention do not correspond to the optimal ones, Molly is ready to demonstrate her dissatisfaction: she lies down and does not move, which frightens her masters.
The lack of oxygen makes it float to the surface of the aquarium, rather than remind you to change at least a quarter of the volume of water.
It turns out that this is not the case. Despite the fact that mollies, as well as all pecillia, are very sociable, they will be against the neighborhood of aggressive individuals, both large and small.
They are very careful about their pride, the fins and the figure tail. Therefore, neighbors who have a tendency to bite them off to their neighbors are unlikely to do.
A good microclimate will develop in an aquarium, if you share it with Molly of the Sword, gourami, and lyalius. You can even goldfish if their size does not exceed the molly themselves.
The principle should be the same: all individuals should inhabit simultaneously and be approximately the same size.
Black mollies under favorable conditions can interbreed with swordtails. As a result of this, very beautiful and original red-black fishes have turned out, similar in their lives to the pesillium.
From the age of 5-6 months, the female molly is ready to reproduce offspring. In males, this period comes a little later – about a year.
Mollies are viviparous fishes, reproduction of which can occur every 40-45 days.
Maturing of the young occurs inside the female after fertilization with seminal fluid of the male. She gets inside the molli through a special body.
However, fertilization of eggs at all is not always possible. Therefore, their maturation can occur gradually: the young can be born within a week or two.
The reproduction of mollies occurs in the algae, which creates the conditions for the protection of the fry from a possible attack of neighbors in the aquarium. In principle, for this it is worthwhile to single out a separate aquarium, and even the female should be transplanted after the birth of fry.
To do this on time, it is necessary to notice in time the enlarged and rounded abdomen of the female and the appearance of a black spot near the anal fin.
It should be noted immediately if the conditions in the aquarium are at least somewhat different from those required, the reproduction of mollies will not occur. And even if this happened, the fry are unlikely to be viable.
First of all, you should take care of the freshness of the water in the aquarium, its aeration, full filtration. At least weekly change of a quarter of the volume of water is necessary, it should be separated, slightly warm, not contain bacteria and even snails.
Secondarily, you need adequate nutrition. Molly’s fry love nauplii artemia, cyclops, “live dust”.
You can treat them and artificial food for fry. Like adults, molly fry will not abandon vegetable feed, both frozen and freshly grated: cucumber, zucchini, patison and others.
Excess feed needs to be removed after 20 minutes, since its beginning process of decay will provoke biological contamination of water.
An experienced aquarist will immediately advise to salt the water in the aquarium. The calculation is simple: a tablespoon of ordinary table salt per 10 liters of water.
The second step: bringing the temperature to 27 °.
Such conditions are natural in the main habitat. Therefore, they are a stimulus to reproduction, prevention of diseases and the key to a good mood of these universal pets – mollies.
Now it is clear that the “simple and unpretentious” mollies will become so only when all its requirements and whims are met!
