Corydoras aeneus
A highly popular, peaceful schooling catfish known for its armor-like scales (scutes) and active bottom-feeding behavior. They are essential clean-up crew members but require a dedicated sinking diet (not just leftovers). Sand substrate is strictly required to prevent erosion and infection of their sensitive barbels. They are 'gut breathers' and will occasionally dart to the surface to gulp atmospheric air.
Corydoras panda
A highly popular, peaceful schooling catfish easily identified by its black eye patches and spotted dorsal/tail fins, resembling a giant panda. Native to the cooler waters of the Ucayali river system in Peru, they require slightly lower temperatures than many standard tropical community fish. They are strict bottom-dwellers that sift through the substrate for food.
Pimelodus pictus
An extremely active, striking silver catfish with black spots and incredibly long barbels, native to South America. While peaceful toward similarly sized tank mates, they are highly effective nocturnal predators that will easily swallow small fish (like Neon Tetras) whole. They are scaleless and possess sharp pectoral spines that can easily become entangled in aquarium nets.
Phractocephalus hemioliopterus
A massive, fast-growing predatory catfish from the Amazon basin. Famous for its voracious appetite, bulldozer-like behavior, and distinct red caudal fin. Due to its enormous adult size (often exceeding 4 feet), it is strictly a 'monster fish' that requires a heated indoor pond or a colossal custom aquarium. It is highly predatory and will swallow absolutely any tank mate that can fit into its cavernous mouth.
Corydoras sterbai
A highly popular and peaceful schooling catfish known for its striking white-on-black spotted pattern and bright orange pectoral fins. Uniquely among Corydoras, they thrive in higher temperatures, making them excellent bottom-dwelling companions for warm-water species like Discus. They are obligate shoalers and must be kept on fine sand to prevent the erosion and infection of their delicate barbels.
