How long do swordtails take to spawn?

Question

I have 1 spotted dora 1 fighting fish and 2 angels in the tank is this safe?

Answer 1

Your female swordtail will definately get pregnant because of the male's persistance. Although, because of the angels in there, your fry will most likely get eaten as soon as they are born unless your tank has a lot of plants in it.
I don't know how long the females stay pregnant until they give birth but I think I recall it being up to a month until they give birth.

Answer 2

Swordtails like most other common livebearers mate almost constantly. Once the female is pregnant it takes about 30 days gestation before the babies are born. The babies will be food for the other fish in the tank including mom and dad unless you take measures to seperate them from all of the adult fish.
