Viviparous

Fish whose eggs develop in the body of the female and whose embryo is nourished by the maternal organism.

The term "viviparous" refers to a mode of reproduction in certain animals, in particular fish, in which the eggs are fertilized inside the body of the female and the little ones are born alive and already formed.

Unlike the fish that are oviparous (which lay eggs that develop outside the female body), viviparous fish do not need to lay eggs. Their reproductive cycle is therefore much shorter and they can give birth to many small ones in a short time.

There are several advantages to be viviparous. First of all, the little ones are much more developed when they are born, which allows them to fend for themselves from the start. In addition, the female can control the size of its scope depending on the availability of food and the environment.

However, there are also drawbacks to be viviparous. First of all, the female must provide a large amount of food and care for small people during pregnancy, which can be exhausting. In addition, pregnancy can be stressful for the female and can cause complications.

There are many examples of viviparous fish in the world of aquarophilia, including guppys, mollys, plasses and swordtails. These fish are popular among beginner aquariophiles because they are easy to reproduce and raise. However, it is important to find out about the specific needs of each species before deciding to raise viviparous fish.
