60 adorable fish species, 117 appearances

Aquarium Days includes guppies, danios, corydoras, bettas, discus, arowanas, koi, freshwater stingrays, and more. Some species come in different colors and patterns, for a total of 117 appearances.

Different species move in their own ways: some swim in schools, some stay near the surface, and others spend most of their time near the bottom. New fish are automatically recorded in the catalog, making it easy to see which species and appearances you still need to collect.
