Vivipars aquarium fish: list (list), popular species for the aquarium, photos, names

The maintenance of viviparous aquarium fish is considered to be something difficult among beginning aquarists, but this is not at all the case. Viviparous fishes are common in Russia and abroad due to simple care and undemanding to environmental conditions.

That is why zhivorodki considered frequent pets freshwater and saltwater aquariums.

The viviparous fishes are called those fishes that do not lay eggs during spawning, and give birth to live fry already adapted to the environment.

But it is impossible to call this process a live birth, as in higher animals. Fry all the same for a long time form and grow in eggs, located in the abdomen of the mother.

Only after that they are born. That is why sometimes fish are called not viviparous, as higher animals, but ovoviviparous.

Live-bearers are distinguished by endurance and unpretentiousness in care.

The famous aquarist Bernd Posekert described some popular species in his work, including viviparous aquarium species of fish. Most often for aquariums choose small fish with a calm character that peacefully belong to other species.

The group maintains and maintains a strict hierarchy, and each fish has its own place. They live in the upper and middle layers of water.

In an aquarium with 8–10 individuals, 40–50 liters of water with a large amount of dissolved oxygen is sufficient.

Viviparous aquariums are easy to clean and not too demanding of conditions. Life givers have high adaptability to new living conditions and are able to withstand temperature fluctuations, lack of oxygen, water pollution or insufficient lighting.

List of care features:

  • In order for the pets to be healthy and comfortable, they will need adequate lighting. It can be daylight or artificial light. If you choose daylight natural light, then the aquarium should be located near the window and to prevent drafts. And also if daylight is insufficient, then use additional lighting. Good lighting will help the fish to feel normal and fully reveal their color, which pales with lack of lighting.
  • Viviparids feed on all kinds of plant and animal origin of food: dry, frozen, alive. In the diet must contain vegetable ingredients, vegetables, fruits. Their number can reach up to half of the total feed. When feeding vegetables and fruits, they are first poured with boiling water and only then are fed to fish. Mature individuals are fed once a day, and the fry require 4 servings of feed per day. Malkam feed carefully crushed. In times of hunger, they can only eat plants.
  • Most often viviparous fish are schooling animals, therefore keeping them alone is dangerous for the psyche of the fish. To avoid clashes and fights with a large population of the aquarium, it is necessary to prevent a large number of males. To each of the males to correlate 2-4 females. Then the probability of fights will decrease.
  • Although live beetles are able to survive in adverse conditions, it is better to maintain clean water in the aquarium with a substitution of a portion of water every week.
  • Water temperature is from 20 to 30 degrees Celsius, and hardness and acidity are average.
  • Conditions should be close to natural. Plant enough vegetation.
  • It is recommended to equip the tank with aerating and filtering devices.

Viviparous aquarium fish hardy and unpretentious:

  • The temperature regime is not too important and its variation is wide.
  • The size of an aquarium is not important for zhivorodkam – most of them are able to feel comfortable in the cramped conditions of a small displacement aquarium.
  • Water hardness does not matter much either, and water can be both soft and hard.
  • Reproduction live beetle – easy.

The distinctive features of viviparous are considered to be that they breed easily in an aquarium and have high fecundity.

Puberty of fish occurs at 4 months after birth.

In the female, caviar is formed in the abdomen, and the male fertilizes it with seminal fluid using gonopodium. During pregnancy, the abdomen becomes rounded, and as the birth approaches, near the anal fin a dark spot appears. Eggs hatch after a month and a half and are born.

The female is able, after 1 fertilization by the male, to perform labor 3–4 times more. At one time, the female is able to give birth to 170 fry.

After birth, the fry float to the surface of the water, straighten their swim bladder with air and are already able to live independently. Begin to eat on the second day of life.

For a comfortable stay you will need plants in which the fry after birth can hide, for example, Riccia. Adult fish and fry are kept in separate tanks, because fish often eat their offspring.

With the joint content of the inhabitants provided a sufficient amount of food, then the fry will survive.

Female and male live beetles are easily distinguishable between themselves. In almost all species, females are larger and more massive, and males are smaller and graceful.

The females are endowed with a low-key and grayish color, while the males are bright, with long fins of different shapes.

But the main difference will be the shape of the anal fin: in mature males, it lengthens and becomes an organ for fertilization of the calf inside the female – gonopodia. In females, the anal fin has a rounded shape and small size.

Viviparous fishes are considered the best first pets of novice aquarists. These creatures are unpretentious in the care, and attract the attention of bright color and behavior.

Live beetles are universal and able to live both in freshwater aquariums and in marine ones. These features make viviparous fish an excellent choice for acquiring an aquarium.

With their help, each tank will become a source of beauty, and let you enjoy the closeness of nature in the house.
