Viviparous fishes in an aquarium

In general, almost all viviparous fishes require the same conditions for themselves: a certain temperature, water hardness, the presence of algae in the aquarium. All viviparous fishes like constant water temperature: 22-26 ° C. At a lower temperature, the fish become sluggish. But the fact is that viviparous fishes perfectly adapt to temperature changes, so they do not need to be kept in a heated aquarium. An exception is the molliness of the bucket. These fish are very poorly adapted to lowering and rising temperatures (below 20 ° C and above 26 ° C).

For most viviparous fishes in an aquarium, water of medium hardness or hard. In soft water fish do not feel veryOK. Also, for the well-being of fish, a weekly substitution of 20% of the volume of water is mandatory. Fresh water is a guarantee of good health and stimulation of fish for reproduction.

With the chemical composition and food for viviparous fish in the aquarium is not so simple. So, for guppies, pecilions, sword-bearers and limitsOnly hard water with an alkaline reaction is required. But there are different kinds of other small viviparous fishes that prefer soft and acid water. Therefore, it is very important to choose fish for which the same conditions are required.

Many beginner aquarists make the same mistake in feeding fish. Viviparous fishes feed mainly on plant foods. Therefore, to transfer fish only to live foodit is impossible. Although without live food, fish will not be able to live normally either. Combine different types of feeds: tubing, bloodworm, coretra, scalded and chopped dandelion leaves, salad.

Also for viviparous fish necessarily in the aquarium are various algae. Most of the time viviparous fisheskeep in the middle and upper layers of water. But the newborn fry falls to the bottom, where the first few days remain. To fry survive, and they are not eaten by other fish, the aquarium needs Java moss. In the thickets of moss, fry can find their nourishment. Then the fry grow in the water and swim with the rest of the fish. But again they are in danger of being eaten. Therefore, also take care that in the aquarium there are dense thickets of plants, in which the fry could hide: vallisneria, pinnate, cabobba, ludwigia. Also suitable for the maintenance of viviparous fish are plants that float on the surface of the water.

Now let's list the most common live-born fish you can get. The most famous and unpretentious in the content are aquarium guppies. These are small fish, in which sex demarcism is strongly pronounced. Males are much smaller than females and have a bright color.

Sword-bearers are another common species of viviparous fishes that painted in bright colors: lemon, red-speckled, black, red. A special feature of these fish is the pointed tail in the form of a sword (only in males). Thanks to this tail, it is easy to distinguish females from males.

Varied in their color variations of the pecilia will please any aquarist. These fish have a short dense body with a strong and broad caudal fin. One type of pecilia is Mollies. These fish are very similar to pecilia, but differ from the latter only by a more elongated body and other color.

Relatively large white whales are also viviparous fishes. In aquariums, they grow to 15 cm. White whistles are very similar to small pike. Remember that these fish prefer live food and eat everything that moves.

All the above-mentioned fishes belong to the same family of Pecilia. But not only peciliae are the only family of viviparous fish. Ameca, from the gudiyev family, a very mobile viviparous fish. These fish have a bright shiny scales and a black band on the body, which can be seen only in the morning. Then this strip disappears in bright illumination or becomes hardly noticeable.

There are still other viviparous fishes, of which youcould have in your aquarium: neoheterandia, alfaro turquoise (slightly aggressive), harakodony, limii, xenotoki, etc. The choice of fish is very diverse. But when choosing fish Consider the size of the aquarium and the fact that soon there will be fry in it!
