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.

Amphiprion ocellaris
The ocellaris clownfish — star of Finding Nemo — is the most popular saltwater aquarium fish and one of the best choices for beginner reef keepers. Captive-bred specimens are hardy, readily available, and don't require an anemone host (though they will happily adopt one). They are one of the few marine fish that breed regularly in home aquariums.
