The main difference between the live-bearing fish lies in their name. Instead of throwing eggs, such fish give birth to the fry alive. Eggs are attached to the wall of the uterus of the fish and develop there due to nutrients received from the mother. After the birth, the young man lives for a while at the bottom, and after a few days they rise to the rest of the fish in the upper layers of the water. Approximately six months later the male becomes a full-fledged sexually mature fish, capable of procreation.
The process of intrauterine development of fry in viviparous fish can take about 30-40 days. Before sweeping the fry, the belly of the female becomes almost rectangular. An interesting feature of viviparous fish is the ability to multiple genera. After a single fertilization, a female, for example, a guppy, can give birth to 6-8 times.
The number of fry that the female fishes bears and gives birth is not constant and depends on many conditions:
- age of the fish;
- size;
- power supply;
- conditions of detention.

Sword-bearers also delight their owners with a variety of bright colors - this is lemon, and red, and red-speckled. Fish pecilia can have a color of various shades, from black, gold to marble.
Viviparous aquarium fish: maintenance and care

Viviparous aquarium fish, such as pecilia and sword bearer, love water of high rigidity with an alkaline medium. These wishes are better to perform, so your pets will be healthier.
Viviparous aquarium fish prefer an aquarium of small size, with a volume of 5-6 liters. If there are a lot of fish, then choose an aquarium based on the volume of 1.5 liters of water per fish. Lighting is best natural, but if this is not possible, purchase a special lamp. Adjust the degree of illumination so that it's light enough, but the algae do not bloom.
As for the vegetation in the aquarium in viviparous fish, then it must be many. Take care that the bottom is Javanese moss, in which the fry can hide and feed after their birth. In the upper part of the aquarium there should also be thick algae, such as pinnate, ludwigia and others. You can also use floating on the water plants.
The content of viviparous aquarium fish involves feeding them with plant and live food. You can mix different types of food and add to the diet finely chopped lettuce or dandelion. Do not transfer fish solely to vegetable feed.
Keep viviparous fish of different species can be in one aquarium, if the conditions of their content are the same. Do not forget about the possible crossing of these fish, the volume of the aquarium for this should be sufficient. In order to prevent cross-breeding, breed fish in different aquariums. To preserve all fry at birth, the female is recommended to be transplanted into a separate container with water and algae.
