Tip 1: How to determine if a fish is pregnant

Breeding aquarium fish is a pretty processlaborious, because in addition to the fact that fish should receive the right amount of food, light and oxygen, it is necessary to determine in a timely manner the very fact of pregnancy and not miss the birth of fry, which otherwise can simply be eaten.

Reproduction of fish, like any other animals,a very complex physiological process, which is always accompanied by a number of features and influenced by the environment, both natural and artificial. Fish, which are ready for reproduction after fertilization, are often required to be kept in special conditions, but for this it is important to correctly determine whether a fish is really pregnant. Each breed of fish has its own signs, which are expressed both in the change in the color of the females, and in the increase in the abdomen.

Swordsmen

Female swordsmen are ready to mate already with 8months, after all at this age at these fishes puberty comes to an end. If the female sword is pregnant, a stain of dark color appears on her stomach, and the abdomen acquires rounded forms. Closer to the birth of the tummy increases and acquires square outlines.

Guppy

Such an aquarium fish as a guppy, which isalso viviparous and very similar to sword-bearers, has its own peculiarities of reproduction. To become pregnant with a female guppy does not need the constant presence of a male, this fish can repeatedly throw fry from one produced pairing. To understand that the fish is pregnant is easy enough: its sides and abdomen increase at times. Just like the swordbearers, the guppy has a dark spot at the back, which increases in size closer to the birth. Thus, the only difference between guppies is the repeated throwing of fry from one partner, while in Sword mice, fertilization occurs once, and the female is immediately planted.

Rooster fish

In the breed of fish-males, puberty occursalready in 4 months, the distinctive sign of pregnancy of the female is a white spot, and not dark, as in other fish, and of course, the rounded stomach. The peculiarity of female males is the process of birth: the male bore a nest from plants, and when the time is right, they with the female freeze in this nest, then smoothly sink to its bottom, where the ejection of eggs takes place. After that, the male protects the eggs for several days, from which the fry appear, and then it is planted, as well as the female that gave birth.

For example, for mating, the water in the aquarium is made warmer, and for a throw, a shell or shelter is installed.

In this case, the pregnant woman can feel the appearance of pulling unpleasant sensations in the lower area belly, shooting pain in the legs and perineum. The pains arise, because the child presses all its weight on nerves, ligaments and nerves.

Fishes are ready for reproduction at about one-year-old age. Males at the time of readiness find a couple, they are looking for a suitable shelter. There they will not let anyone in. The temperature of the water for stimulation of spawning should not be more than 28 degrees. A fish of a parrot during the breeding season sweeps out about 300 eggs, their color is reddish-brown.

As a rule, the pregnancy of a guppy is determined bythe shape of her abdomen. The fact is that the female bearing offspring has a round voluminous abdomen, which immediately acquires a slightly rectangular shape immediately before birth. Sometimes through the gaps, you can observe the fry, and closer to the labor of the guppy appears a dark generic patch, localized on the abdomen. It should be borne in mind that the shape of the head of the fish during this period begins to appear elegant due to the voluminous abdomen. In addition, the pregnant female is characterized by peaceful and calm behavior.

Often before throwing fry at a guppyThe back of the belly becomes dark. In the event that only fish of this family are present in the aquarium, and there are many shelters in the form of stones, driftwood and algae, the female can not be planted. However, if other fish live in the aquarium, the guppies, breeding offspring, must be sent off for the throwing period, and then run back. It is important to remember that fry must be kept in a separate container.

Culling the pregnant female, it is necessary to take into account thatshe is able to eat her fry. Thus, it is advisable to take care of the acquisition of plants in advance, with the help of which they will be able to hide from the mother, temporarily located next to the offspring.

In order for the offspring to have a beautiful color and develop rapidly, they should be fed a variety of foods three times a day.

In general, pregnancy guppies haveDuration of forty days. During the first week after birth, the fry live in the rider. Then they are transplanted into the most spacious containers. Already a month you can see the distinctive features that allow you to determine the sex of the fry. In females, a generic stain appears near the anus. Males in three months change the so-called anal fin into gonopodia. It should be borne in mind that in order to prevent the reproduction of guppies, the young offspring should be timely distributed on a sex basis and must be kept separately. In winter, it is necessary to observe the water temperature, which should be eighteen degrees of heat. Such actions not only help to avoid unnecessary spawning, but also allow the female to rest from labor.
