Species Profiles
Goldfish
Carassius auratus
Goldfish are among the longest-kept ornamental fish, with a history spanning over 1,000 years. Despite their reputation as easy, bowl-dwelling pets, goldfish actually require spacious tanks with strong filtration. They are cold-water fish that should not be kept with tropical species. Common varieties include comets, fantails, orandas, and ryukins.

Hemigrammus rhodostomus
Rummy nose tetras are considered the ultimate schooling fish in the freshwater hobby. Their tight, synchronized formations are unmatched by any other tetra species. The vivid red nose serves as a health indicator — bright red means healthy, pale red means stressed. They prefer soft, acidic water and are slightly more demanding than neon tetras.
