General Description
The Bronze Cory (Corydoras Aeneus) is a popular species within the aquarium hobby, known for its bronze, golden-green body coloration. This fish belongs to the Callichthyidae family and can grow up to 7.5cm in size. It is characterized by the presence of bony plates on its flanks, giving it an armored appearance.
Aquarium Setup
For optimal care, Bronze Corys should ideally be kept in a group of at least 4-6 individuals in a tank with a minimum size of 72 litres. It's recommended to use fine sand or rounded gravel substrate and provide adequate cover for security. Water conditions should have a pH range of 6.0-8.0, hardness between 36-268ppm, and a temperature of 21-27°C.
Behaviour
Bronze Corys are known to be peaceful and gregarious fish that thrive in group settings. They are facultative air breathers, possessing a modified intestine for atmospheric oxygen uptake. However, caution is advised due to their sharp pectoral-fin spines, which can cause painful stings if mishandled.
Feeding and Diet
As foragers, Bronze Corys are omnivores that accept a variety of sinking dried foods, along with live and frozen options such as bloodworms and Tubifex. Maintaining a diverse diet ensures their optimal health, as they should not solely rely on leftover food in the aquarium.
Reproduction & Dimorphism
Breeding Bronze Corys is similar to other Corydoras species, with a recommended ratio of 2 males to 1 female for successful breeding. Females tend to grow larger and become noticeably rounder and broader-bodied when gravid. Spawning usually involves depositing eggs on tank surfaces, with an incubation period of 3-4 days before the fry can feed on small live foods.
Habitat and Distribution
Originally from Trinidad, Bronze Corys are found in river systems of central and southern parts of the island. Their distribution extends throughout South America, from Colombia to Uruguay and Argentina. However, taxonomic confusion exists due to the presence of similar-looking species, leading to uncertainties about their true taxonomy and distribution.
