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.

Amatitlania nigrofasciata
Convict cichlids are tough, prolific Central American cichlids with distinctive black and white vertical stripes — earning them the 'convict' name. They are extremely hardy, breed readily (almost uncontrollably), and are highly aggressive for their size, especially when protecting fry. They are excellent for beginners who want to keep cichlids but should not be mixed with peaceful community fish.
