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.

Tanichthys albonubes
White cloud mountain minnows are hardy, colorful cold-water fish that are perfect for unheated aquariums and goldfish companions. Their small size, brilliant red fins, and iridescent lateral line make them surprisingly attractive for such a hardy, easy-to-keep species. They are one of the few truly cold-water schooling fish available in the hobby.
