Black Diamond Cory Catfish (Corydoras sp.)
The Black Diamond Cory Catfish is a striking freshwater bottom-dweller prized for its deep, dark coloration and shimmering highlights. Its bold appearance offers a dramatic alternative to more traditionally colored Corydoras while retaining the peaceful personality, social behavior, and entertaining foraging habits that make Cory Catfish favorites among freshwater aquarists.
Like other Corydoras, Black Diamond Cory Catfish thrive in clean, well-maintained aquariums with soft sand or smooth, fine gravel. Their sensitive barbels are used to search the substrate for food, so sharp or abrasive substrates should be avoided. Live plants, driftwood, caves, and shaded resting areas help create a comfortable environment while leaving plenty of open bottom space for foraging.
Black Diamond Cory Catfish are highly social and should be kept in groups of at least six individuals. A properly sized group helps them feel secure and encourages natural schooling, resting, and feeding behavior. They can often be seen exploring the aquarium together before gathering in their favorite resting areas.
These catfish are omnivores and should receive dedicated feedings rather than being expected to survive on leftover food. Quality sinking pellets and wafers can be supplemented with frozen bloodworms, brine shrimp, daphnia, and other appropriately sized foods. A varied diet helps maintain healthy growth, coloration, and body condition.
Their peaceful temperament makes them excellent companions for Tetras, Rasboras, Danios, Gouramis, peaceful dwarf Cichlids, livebearers, and other non-aggressive community fish. They are also excellent additions to planted aquariums because they generally leave healthy plants undisturbed.
