Swordtails are livebearers and can give birth to as many as 80 fry at one time. A spawning box is recommended, or if one is not available, dense floating cover should be provided to protect the fry from the adults. Once sex is determined, the males should be separated because swordtails can begin breeding at as young as three months of age. They will sometimes eat fry. Jumpers by nature, be sure to provide an adequate cover over the aquarium. Males can be aggressive toward one another so care should be taken when housing more than one.
