Pinheiro's Corydoras

Adults of this species reach up to 6 cm in length. Pinheiro's Corydoras is characterized by the typical stocky corydoras body shape, protected by rows of bony plates, as well as sharp spines in the rays of the pectoral fins. It differs from Corydoras sterbai by having a larger reticulated pattern on its body, although the overall pattern is similar.

This fish originates from South America, specifically from the basins of large eastern tributaries of the Amazon, such as the Madeira and Mamoré rivers. It can be found in the Brazilian states of Rondônia and Amazonas, where it inhabits numerous streams, small rivers, and channels, often venturing into flooded areas of humid tropical forests.

This peaceful and friendly fish will fit perfectly into most freshwater aquariums. It should be kept separately from territorial or aggressive species. In their natural habitat, they live in large schools, so it is recommended to keep a group of at least 3–4 individuals. Their activity increases under subdued lighting.

An optimal aquarium for a group of 3–4 fish should have a volume of 60–70 liters. For decoration, a sandy substrate, dense thickets of aquatic plants, and several shelters made of smooth stones and natural driftwood are preferred. To maintain their health, it is necessary to provide a slight current and additional aeration of the water. An important aspect of long-term keeping is preventing the accumulation of organic waste at the bottom of the aquarium. Contaminated substrate can pose a threat to corydoras, causing various diseases. When cleanliness is maintained, Pinheiro's Corydoras is considered an undemanding species. These fish adapt well to various conditions, although they prefer shaded areas with soft, slightly acidic water. Their diet can include most known foods. Live, frozen, fresh, or dry crustaceans and small invertebrates (zooplankton), such as artemia, bloodworms, daphnia, and gammarus, make an excellent choice.

Popular foods will be acceptable for these fish. Live, frozen, fresh, or dry crustaceans and other small invertebrates belonging to zooplankton, such as artemia, bloodworms, daphnia, gammarus, and similar, would be an ideal choice. Since this species is rarely found in home aquariums, precise information about its breeding in artificial environments is not yet available. However, given its genetic proximity to other corydoras, the assumption of a high probability of successful reproduction is well-founded. Details on the breeding conditions of Corydoras catfishes are outlined in a separate publication.

This species is not frequently encountered in home aquariums, so reliable information about its breeding in artificial conditions is practically nonexistent. Nevertheless, given its close kinship with other representatives of the genus Corydoras, a very high probability of successful reproduction can be assumed. More detailed information on the breeding characteristics of Corydoras catfishes can be found in a separate article. Sources: fishbase.de, planetcatfish.com

Like other members of the family, this species lacks scales, which makes it extremely sensitive to water quality and certain medications. Corydoras are susceptible to bacterial infections if their skin or barbels are damaged, which often happens when using unsuitable substrate with sharp edges. As a preventative measure, it is necessary to maintain substrate cleanliness, regularly perform water changes, and avoid using salt in the aquarium, as it is detrimental to these fish.

When selecting individuals, attention should be paid to the integrity of the fins and the absence of visible sores or redness on the body. A healthy fish should be active, well-fed, and have intact, long barbels, which are essential for finding food. Avoid purchasing fish that appear emaciated, lethargic, or show signs of skin damage, as such individuals often struggle to adapt to new conditions after transport.
