Species Profiles
Oscar Fish
Astronotus ocellatus
intermediateaggressive75+ gal
Oscars are large, intelligent South American cichlids often called 'water dogs' for their interactive personality. They recognize their owners, beg for food, and can be hand-fed. However, they grow fast, produce massive waste, and need at least a 75-gallon tank.

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.
