Explaining How Swordtail Fish Give Live Birth
Among swordtail fish, females give birth to living offspring and do not lay eggs.

Most female swordtails will show signs of pregnancy in three months. However, a pregnant female swordtail could show the sign at four to six weeks if she only has one batch of fry or if she is carrying multiple batches.
Female swordtail fish grow larger and their stomachs swell before they give birth.
When female swordtails are pregnant, they will develop a dark spot on their lower stomach. It can take 3-6 weeks for this to happen before the female gives birth.
