Males are distinguished from females usually brighter coloration and the presence of lengthening in the lower part of the tail. Female swordtails are viviparous fish, the fish immediately appears of females are born.

Female destinet puberty 6-8 months. But, surprisingly, the female even at a younger age can be fertilized by the male, i.e., before the onset of puberty. The sperm of the male will stay female until you fertilize it. After single insemination, the female can give birth to a few times. The sword has the tendency to be reborn, that is, to change your gender.

The pregnancy of a goldfish lasts about 30-35 days. Usually visually noticeable that the female’s abdomen has grown. About 2 days before the expected delivery date female the swordsman must be out. It is desirable that the conditions of detention did not differ from that of aquarium. You must put a female with a little greenery anyway. The vegetation will act as a deterrent for future fry. After birth, the mother may eat them, so the fry will look for an opportunity to escape, and will help the plants. The number of fry can be more than 100 pieces. After the female swordsman gave birth, it must be deposited back into the aquarium. The fry grow and develop for the first time by themselves. All this is done for their safety, as in the aquarium they can eat. Feeding the fry can be the same dry food, but additionally shredded. Next, we describe about feeding Malov more.
