General Description
Corydoras Griseus, a member of the Callichthyidae family of Siluriformes, are often referred to as 'armoured' or 'mailed' catfish due to bony plates in place of scales on their bodies. They hail from Brazil and are facultative air breathers with the ability to gulp air at the water's surface. The species' taxonomy can be confusing, and many potentially unidentified species exist, often assigned 'C' or 'CW' numbers in the aquarium trade for organization. Being foraging omnivores, they require a varied diet for optimal health.
Aquarium Setup
Maintain Corydoras Griseus in groups of at least 4-6 individuals in a tank of a minimum of 80 litres. An ideal setup includes fine sand or clean rounded gravel as a substrate and the provision of cover for the fish's security. Water conditions should have a pH range of 6.0-7.5, hardness of 36-215ppm, and a temperature between 20-26°C.
Behaviour
These catfish are peaceful and gregarious, thriving when kept in a group setup. They may occasionally breach the water surface to gulp air, a trait that aids them in low-oxygen environments. It's crucial to handle them with care due to their sharp pectoral-fin spines, which can inflict painful stings.
Feeding and Diet
Corydoras Griseus are foraging omnivores that readily accept sinking dried foods, small live, and frozen varieties like bloodworms and Tubifex. A varied diet is essential for their well-being, and they should not be solely reliant on leftovers in the tank.
Reproduction & Dimorphism
Breeding Corydoras Griseus involves maintaining a ratio of two or more males per female. The females, visibly full of eggs, require a large water change with cooler water to stimulate spawning. The eggs are typically laid on surfaces like aquarium glass or within spawning mops. Females tend to be larger, broader, and deeper-bodied than males.
Habitat and Distribution
Native to Guyana, Corydoras Griseus may be restricted to the Potaro River within the Essequibo watershed. Initially described from specimens collected in small Amazonian water bodies, they are commonly found in the Potaro River region in Guyana.
