Breeding Information: Swordtails are quite easy to breed, largely due to the fact they are livebearers. Be sure to provide plentl of floating plants for cover for the babies because the parents WILL eat them. If you want to maximize the survival rate of the babies, they should be moved to a growing tank once they are free swimming. |
