Black Band Corydoras Care Guide - Tank Setup, Diet & Breeding

Black Band Corydoras are small, armoured catfish with a pale silver, beige or pinkish body crossed by a bold dark stripe running from the snout, through the eye and along the upper side of the body. Their compact shape, dark markings and lively bottom-dwelling habits make them especially appealing to community-aquarium keepers.

Like other Corydoras, they possess rows of overlapping bony plates and sharp spines in the dorsal and pectoral fins. They regularly rest on the substrate, investigate objects with their barbels and make quick trips to the surface to gulp atmospheric air, an adaptation that helps them cope with oxygen-poor conditions in nature.

These catfish are peaceful, social and most confident when living in a proper group. They spend much of their time foraging together across the bottom, but they can also become surprisingly active, darting around the aquarium and displaying playful interactions with one another.

In the wild, Black Band Corydoras are associated with shallow Amazonian tributaries, where leaf litter, sand, roots and aquatic vegetation create a varied habitat. Their striking stripe is thought to help break up their outline among shadows and debris on the riverbed.

Black Band Corydoras originate from western South America, particularly tributaries and river systems in Peru, including waters associated with the upper Amazon basin. They inhabit warm, slow to moderately flowing freshwater environments with soft sediments and submerged vegetation.

A group of Black Band Corydoras should be provided with an aquarium of at least 75 litres, ideally with a footprint of around 60 by 30 cm or larger. Use soft sand or another smooth, fine substrate so their sensitive barbels are not damaged while foraging. Include driftwood, rounded stones, broad-leaved plants and shaded areas, while leaving open substrate for group feeding. Gentle to moderate water movement, good filtration and well-oxygenated, stable water are important, and a secure lid is advisable because Corydoras may leap when startled.

Up to approximately 5.5 cm (2.2 inches) in standard length. Females are usually larger and more robust than males, with some reaching around 6 cm (2.4 inches) overall.

Black Band Corydoras are omnivorous bottom feeders that should receive a varied diet of sinking catfish pellets, granules and tablets, supplemented with frozen or live foods such as bloodworm, daphnia, brine shrimp and mosquito larvae. Blanched vegetables can occasionally be offered, although animal-based foods are particularly useful for conditioning adults and supporting growth. Make sure food reaches the substrate rather than being consumed entirely by midwater tankmates.

Black Band Corydoras are peaceful community fish and can be kept with similarly gentle tetras, rasboras, pencilfish, small danios, peaceful dwarf cichlids, hatchetfish and other non-aggressive South American species. They also mix well with calm livebearers and other peaceful bottom dwellers when there is enough space. Avoid large or predatory fish, fin-nipping species and boisterous bottom feeders that may outcompete or injure them. They should not be housed with aggressive cichlids or fish large enough to swallow them.

Black Band Corydoras are egg scatterers that can be bred in a mature, well-conditioned aquarium. Feed a varied diet of live or frozen foods, then encourage spawning with a series of partial water changes using slightly cooler water. Females carry the eggs between their pelvic fins before placing them on aquarium glass, plants or other smooth surfaces. Remove the adults or transfer the eggs to a separate hatching container, as the eggs may be eaten. The eggs generally hatch in around three to five days, with fry accepting newly hatched brine shrimp and other suitably tiny foods once their yolk sacs are absorbed.

Females are generally broader-bodied and slightly larger, especially when viewed from above, while males are slimmer and a little shorter. The difference is most noticeable when mature females are carrying eggs.
