Species Overview

Channel Catfish

The channel catfish is the most abundant and widely fished catfish species in North America. It has a keen sense of smell, with taste buds distributed across its entire body, enabling it to locate food in murky water.

Corydoras

The peppered corydoras is a peaceful bottom-dwelling catfish native to South American rivers. It uses its barbels to sift through substrate for food and should be kept in groups of six or more. It can gulp atmospheric air in low-oxygen conditions.
