Species Profiles
Swordtail
Xiphophorus hellerii
Swordtails are hardy, colorful livebearers named for the distinctive elongated lower tail fin (the 'sword') found on males. They come in many color varieties including red, pineapple, marigold, and tuxedo. Larger than guppies but just as easy to care for, swordtails are excellent community fish that prefer hard, alkaline water.
