Live-bearing aquarium fish
Among the inhabitants of the aquarium viviparous fishes aquarium occupies one of leading places. Most fans of aquarium fish begin their fascination with viviparous species. The interest in these fish could drag on for years, not only beginners but also for experienced aquarists. Such keen interest is explained by the peculiarities of reproduction viviparous fish, easily their contents, as well as a large variety of offspring, created by breeding and crossing varieties. Such features give a good chance for a relatively short period of time to obtain a variety of varieties of aquarium fish, which will differ from existing species.
Especially breeding viviparous aquarium fish
The reproduction and the content of viviparous fishes aquarium is quite simple. Excellent adaptability enables them to tolerate the increasing temperature and strong pressure, and very hard water. For most species of viviparous fish do not need an aquarium large dimensions. It is desirable that the lighting was quite bright and natural, but in the absence of suitable artificial light sources. Good conditions for development and reproduction of viviparous fish are in aquariums with the presence of free space for swimming and at the same time dense thickets of plants.
plants for viviparous fish
In aquariums viviparous fishes should be a lot of plants. Live-bearing aquarium fishes breed even in a community tank, in which at small density of fish can be grown floating, small-leaved, dense plants, such as the Ricci or Salvinia. In the heart of the aquarium, is found there should be enough space to swim adults. The most favorable temperature for the maintenance of the majority of viviparous fish is + 20-24°. The composition of the water, as a rule, for keeping this kind of aquarium fish is not significant, it can have a significant or medium rigidity, to be “settled”, fresh or even old.
Depending on the age of the female, and also the conditions of her imprisonment, the duration of development of eggs in viviparous fishes aquarium is 30 to 50 days (also depends on type of fish). The female’s anal fin during this period quite clearly see a dark spot, which is called the “spot the pregnancy”. Literally 2-3 days before the “birth” of the abdomen of the female acquires a rectangular shape. Number of juveniles of the viviparous females depends on the species, age and habitat conditions. After hatching, the fry immediately rise to the surface of the water to fill the air of the swim bladder, they are literally from the first days begin to feed on small crustaceans and to save his life from adult fish.
Best possible breeding viviparous fish, if a certain type to be separated from the others. Shortly before the “birth” of the female is placed in a separate vessel with a large number melanistic of plants that can be located on the bottom of the vessel, and on the surface of the water. You can put the female in a separate aquarium insulator, hole which would not allow her to come in General compartment. The holes in the bottom should allow the fry right after birth to fail, and then to emerge. The size of fry is born only from 0.6 to 1 cm.
Straightforward and the feeding of the fry, they eat almost any food of a suitable size, however, it is best to give them small Cyclops, Daphnia and Artemia juveniles. Greatly facilitates the process of feeding using home-made or purchased in specialty shops feeders type “reflex”. The maturation of the fry live-bearing aquarium fish occurs quite rapidly, in 4-6 months they become Mature individuals. Females are viviparous externally, the fish are larger than males, but males are more expressive color.
Species of live-bearing aquarium fish
To viviparous fish is part of a large group of fish in the salted and fresh waters of South America. All kinds of live-bearing aquarium fish are distinguished from others by the fact that fertilization of eggs occurs inside the female’s body, are born already fully formed fry that are ready to eat. The greatest interest in the breeding of viviparous fishes raises the possibility of breeding new species, but to practice of selecting and crossbreeding different subspecies viviparous fish it is necessary to understand the biology of this group of aquarium fish. This requires, as a rule, several aquariums, as well as theoretical training. To have a clearer idea of what live-bearing aquarium fish, let’s look at their most prominent representatives:
