Between insemination, and the fry being born, it takes 28-31 days, give or take a day,
You will notice the female getting fatter and fatter. If she is a pale colour, you will see a gravid spot, just in front on her tail on her belly, which is actually the eyes of the babies.
She will give birth to 10-80 live fry. Be sure to provide lots of plants for them so the parents won't eat them. It can't hurt to set up a second tank for the babies. You can catch them with a net and put them in a new tank (use some of the gravel and water from the parents' tank for identical water conditions).
Just before she gives birth, she may stop eating, and will swim up and down the tank erradically. At this time, if you choose to, you can put her in a breeding net, which she stays in and gives birth to the babies, then you remove the female so she can not eat the babies. I do not recommend this because being netted and kept in a small net is stressful for the female, but others have had success with this method.

From the time of egg fertilization it takes approximately four weeks for the fry to fully develop. Subsequent broods will follow at the same four week intervals, however temperature and the length of daylight can play a factor. Longer days and higher temps result in shorter periods of time between broods. Birth almost always occurs at dawn or shortly thereafter. Brood sizes range from 50 to 200.

A healthy swordtail will give birth just about once a month, You can tell when she is about to give birth when she "squares off," meaning her belly will look like it has corners, instead of being rounded. At this time, it would be a good idea to move it to a breeding tank, in order to keep other fish(and even the mother) from eating the fry.

The gestation period for livebearers is usually 28 days but can range from 20 to 40 days. The advice in that answer about tanks and moss etc is spot on.

Only a few weeks and they have live births so get A LOT of that fine moss for the tank. If you can, put the mom in a maternity tank (they are about 5" square) until she gives birth. She WILL turn and eat the babies (so will the other ones if she is not seperated), so this tank will give the babies a retreat to get to the moss.

do not pass away her interior the breeding internet until you recognize she would be in a position to grant start very quickly (interior of an afternoon). that's incredibly stressful for her to be in the variety of small section, and he or she desires to swim. you will see signs and indicators while she is approximately to grant start. First, her abdomen would be very almost sq.. She could additionally end ingesting. and he or she would be in a position to swim unevenly up and down or right into a nook of the tank. launch her until she is approximately to grant start. If she does interior the tank, you could genuinely capture the babies with a fish tank. purely grant moss / flowers for them to cover in. while did she final have babies, do you recognize? they have them approximately each 28-30 days.
