Blackfin Corydoras

The blackfin corydoras is recognized by the small dark spots on its pale gray–beige body, the dark band running over the eye and the large black blotch covering the front of the dorsal fin. Its scientific name also means "white–black." Adults are around 5 cm. Since many spotted Amazon corydoras look alike, this black area on the dorsal fin is a good distinguishing mark in the store.

• At least 60 liters for a group of 6–10; a large footprint.
• Fine, rounded sand substrate; roots and shaded planted corners.

Make sinking tablets and granules the staple; supplement with frozen bloodworms, brine shrimp and daphnia. Feeding in the evening lets bottom dwellers eat in peace.

A peaceful, social bottom dweller; it sifts the bottom in a group. It leaves fish and shrimp alone.

Good companions: tetras, rasboras, pencilfish, dwarf cichlids, otocinclus, shrimp, other corydoras.

Avoid: cichlids that claim the bottom, large and predatory fish it would fit into the mouth of.
