Pepper Corydoras Care Guide - Setup, Feeding & Breeding

Pepper Corydoras are small, armoured catfish with a distinctive mottled pattern of dark grey and brown markings over a pale silver-green or bronze background. Their rounded bodies, high-set eyes and underslung mouths give them the classic corydoras appearance, while their spotted pattern provides excellent camouflage over gravel, leaf litter and sand.

These peaceful bottom dwellers are active, sociable and full of character. They spend much of their time searching the substrate with their sensitive barbels, but will also occasionally dash to the surface to gulp air, an adaptation that helps them survive in oxygen-poor waters. Their habit of resting together and exploring in a group makes them especially engaging to watch.

In the wild, Pepper Corydoras live in freshwater habitats with gentle currents, soft sediment and a mixture of aquatic vegetation, roots and fallen leaves. They are well adapted to cooler conditions than many tropical aquarium fish, and their robust nature has made them one of the most familiar and widely kept corydoras species.

Although they are often called bottom-feeding catfish, Pepper Corydoras are not scavengers that can live on leftovers alone. They are active foragers with a varied natural diet, and their peaceful temperament makes them a dependable choice for a well-planned community aquarium.

Pepper Corydoras are native to southern South America, including southern Brazil, Uruguay and parts of northeastern Argentina. They inhabit slow-moving streams, shallow rivers and marginal waters with soft bottoms and plenty of submerged cover.

A group of Pepper Corydoras should have an aquarium of at least 75 litres, with a footprint of around 90 cm by 30 cm or larger to provide a generous uninterrupted bottom area. Use soft sand or smooth fine gravel to protect their delicate barbels, and include driftwood, smooth stones, hardy plants and shaded areas for cover. Gentle to moderate filtration, good oxygenation and open floor space are important, while sharp gravel, excessive detritus and strong, turbulent currents should be avoided. A secure lid is advisable because corydoras may leap when startled.

Females can reach about 7 cm (2.8 inches), while males usually remain smaller at around 5.5–6 cm (2.2–2.4 inches). Exceptional females may approach 7.5 cm (3 inches).

Offer a varied diet based on good-quality sinking corydoras pellets or wafers, supplemented with frozen or live foods such as bloodworms, daphnia, brine shrimp and tubifex. Small portions of sinking granules are useful because they reach the bottom where these catfish feed. Feed once or twice daily in quantities they can finish promptly, and make sure other fish do not consume all the food before it reaches the substrate.

Pepper Corydoras suit peaceful community aquariums and can be kept with small tetras, rasboras, danios, white cloud mountain minnows, peaceful livebearers, honey gouramis and other non-aggressive community fish. They also mix well with other similarly sized Corydoras when plenty of floor space is available. Avoid large or predatory fish, fin-nippers, aggressive cichlids and boisterous bottom dwellers that may outcompete or injure them. They should never be housed with fish that are likely to harass their barbels or swallow them.

Pepper Corydoras are egg scatterers that can often be encouraged to spawn with excellent feeding and a partial water change using slightly cooler, clean water. Condition a group with live or frozen foods, then provide broad plant leaves, fine-leaved plants or spawning mops for the adhesive eggs. The adults should be removed or the eggs protected, as they may eat them. Eggs usually hatch in around three to five days, and the fry can be raised on infusoria or finely powdered food before moving on to newly hatched brine shrimp.

Females are generally broader-bodied and larger than males, especially when viewed from above. Males are usually slimmer and slightly shorter, with a more streamlined profile.
