Species Profiles
Ocellaris Clownfish
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.

Sewellia lineolata
Hillstream loaches are fascinating flat-bodied fish that resemble tiny stingrays. They are specialized for life in fast-flowing, oxygen-rich streams and use their modified pelvic and pectoral fins to grip smooth rocks in strong current. Their unique appearance, algae-eating habits, and cool-water preference make them popular with experienced fishkeepers looking for something different.
