Armored Cory

Adults of this catfish reach approximately 6 cm in length. Their body is white, adorned with a pattern of black speckles that also extends to the tail and dorsal fin. Important features include thickened first fin rays, which are sharp spines, as well as modified scales that have transformed into strong plates. These adaptations provide the catfish with reliable protection from small predators.

The species inhabits South America, primarily the Huallaga River basin in Peru, as well as the upper reaches of the Madeira River in Brazil and Bolivia. In the wild, it lives in bodies of water with soft, slightly acidic, or neutral water. It prefers areas with sandy bottoms, where it leads a benthic lifestyle.

A peaceful and social species, exhibiting schooling behavior. To ensure comfort and reduce stress levels, it is necessary to keep a group of at least 4–6 individuals. It coexists well with small, peaceful fish that occupy the middle and upper water layers. Avoid cohabitation with aggressive or large species that may perceive the catfish as prey.

Corydoras are generally considered easily accessible and undemanding aquarium fish. Corydoras armatus is no exception, making it an excellent choice even for beginner aquarists. This unpretentious fish can adapt to various conditions, mimicking both flowing rivers and stagnant backwaters or swamps. Thus, the specific aquarium setup is not crucial. The main thing is to provide a soft sandy substrate or fine gravel, as well as several shelters, which can be created using driftwood or dense plant thickets. Regarding feeding, since these catfish spend most of their time at the bottom, it is preferable to give them sinking foods, as they are reluctant to rise to the surface. Their diet can include dry flakes and granules, as well as live or frozen foods such as bloodworms, brine shrimp, and daphnia, which are popular in the aquarium hobby. In terms of behavior and compatibility, these fish coexist perfectly with many non-aggressive species of comparable size. They also prefer to be in groups of their own kind, so it is recommended to acquire them in groups of 4 to 6 individuals.

An omnivorous species that readily accepts high-quality sinking dry foods in the aquarium, as well as frozen and live foods such as bloodworms or tubifex. The diet should be varied to maintain health. Do not expect the fish to feed exclusively on the leftover food of other inhabitants.

Reproduction is typical for the genus. To stimulate spawning, water changes with cooler, fresh water are often used. It is recommended to use a separate breeding tank to avoid other fish eating the eggs. Fry require clean water and fine starter foods.

Sensitive to water quality and substrate condition. When kept on a sharp or dirty substrate, damage to the sensitive barbels is possible, which opens the way for bacterial infections. Prevention includes using fine sand, regular gravel vacuuming, and timely water changes.

When purchasing, active fish with clean skin without visible spots, sores, or fin damage should be chosen. It is important to ensure the integrity of the barbels, as their absence is a sign of poor keeping conditions. The fish should exhibit natural activity in the bottom layer.
