8.1.6 Number of young ones

The number of young ones i.e. brood varies from fish to fish and also it depends on the size, feed given and tank environment. In an average 20-40 young ones can be expected.

Swordtail maximum 200 numbers.

After 2-3 days the female again becomes pregnant even without the contact of male. The sperm transferred during first mating is stored in the female body and when eggs are formed the sperm will join with eggs and form young ones. Thus by single mating youngones can be released 8-10 times. In an year it is possible to get young ones 10 times from one female.
