Catfish

Catfish, particularly Corydoras (or "Corys"), are a popular choice for freshwater aquariums due to their peaceful nature and bottom-dwelling behavior. Corys are small, social catfish that prefer to live in groups, making them an excellent addition to community tanks. They are known for their ability to clean up leftover food and debris from the tank floor, helping maintain the aquarium's overall cleanliness. Corys come in a variety of species, each with unique patterns and colors, and they thrive in well-planted tanks with soft substrate to protect their sensitive barbels. They are hardy, easy to care for, and a favorite among aquarists for their active yet gentle behavior.
