Species Profiles
Congo Tetra
Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.

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.
