Corydoras Virginiae

Datasheet

General Description

The Corydoras Virginiae, also known as the Miguelito Cory, belongs to the family Callichthyidae and is classified under the order Siluriformes. These fish are peaceful and gregarious, thriving best when kept in a group of at least 4-6 individuals. They are known for their facultative air-breathing ability and possess modified, highly vascularized intestines that aid in oxygen uptake. With a maximum size of 6.0cm, these fish are often referred to as "Virginias catfish," and they belong to the genus Corydoras, which contains over 150 valid species.

Aquarium Setup

For the ideal aquarium setup, it is recommended to use a substrate of fine sand, although rounded gravel can be a suitable alternative if maintained meticulously clean. Decor options are flexible, but it is advisable to provide some cover to give the fish a sense of security. The water conditions should be maintained with a hardness of 36-215ppm, pH ranging from 6.0 to 7.5, and a temperature between 22-28°C (see table).

Behaviour

Miguelito Corys are peaceful and thrive in the company of their kind. They exhibit gregarious behavior and should be kept in groups to ensure their well-being. They occasionally rise to the surface to take in gulps of air due to their air-breathing capability. It is important to note that the stiffened pectoral fin spines of these fish can cause painful stings, and caution should be exercised when handling them.

Feeding and Diet

Corydoras Virginiae are foraging omnivores and accept a variety of sinking dried foods, as well as small live and frozen varieties like bloodworms and Tubifex. Maintaining a varied diet ensures the fish remain in optimal condition. It is crucial not to rely on leftover food from other tank inhabitants to sustain them, as they require a well-rounded diet to thrive.

Reproduction & Dimorphism

In terms of sexual dimorphism, female Miguelito Corys are notably rounder and broader-bodied than males, especially when they are gravid. Although specific details on the reproductive behavior are limited, it is known that these fish are egg layers whose breeding may be stimulated by changes in water conditions or other environmental cues.

Habitat and Distribution

The Corydoras Virginiae is endemic to the rio Ucayali in Peru, with the type locality being in that region. These fish are native to this drainage area and are adapted to the specific conditions found in their natural habitat. Their ability to thrive in oxygen-deprived environments makes them well-suited for varying water conditions, given proper care in an aquarium setting.
