Cope’s corydoras
Introduction
Cope’s corydoras (Corydoras copei) is a small, peaceful catfish species cherished by aquarists for its gentle nature and engaging behavior. Native to South America, these bottom-dwellers are known for their nocturnal habits and thrive in well-planted aquariums with soft substrates. Their manageable size and compatibility with other peaceful species make them an excellent choice for both novice and experienced fishkeepers.
Care and Environment
Providing optimal care for Cope’s corydoras involves replicating their natural habitat and meeting their specific needs.
What is the minimum tank size for Cope’s corydoras?
A minimum tank size of 60 liters (15 gallons) is recommended to accommodate a small group of these social fish.
What are the ideal water parameters for Cope’s corydoras?
Maintain water temperatures between 22–26°C (71.6–78.8°F), a pH range of 6.4–7.3, and water hardness of 3–19°N (53.57–339.29 ppm).
What type of substrate is best for Cope’s corydoras?
Use fine sand or smooth gravel to protect their sensitive barbels, which they use to forage along the bottom.
Incorporate live plants, driftwood, and caves to provide hiding spots and mimic their natural environment. Ensure gentle water flow and perform regular water changes to maintain high water quality. As omnivores, Cope’s corydoras should be fed a varied diet, including sinking pellets, algae wafers, and occasional treats like bloodworms or brine shrimp.
Origin and Habitat
Cope’s corydoras are native to the river basins of Peru in South America. These habitats are characterized by soft substrates, dense vegetation, and slow-moving waters, providing ample hiding spots and foraging opportunities. The natural environment features gentle water flow and a variety of plant life, creating a serene setting that supports the species' well-being.
Temperament and Compatibility
Cope’s corydoras are peaceful and gregarious fish that thrive in groups of at least 4–6 individuals. They are compatible with other non-aggressive species, making them ideal for community tanks.
Do Cope’s corydoras need to be kept in groups?
Yes, they are shoaling fish and should be kept in groups to promote natural behaviors and reduce stress.
What tank mates are suitable for Cope’s corydoras?
Suitable tank mates include small tetras, rasboras, and other peaceful fish that share similar water parameter requirements.
Are Cope’s corydoras aggressive?
No, they are known for their peaceful nature and do not exhibit aggressive behavior towards other fish.
Interesting Facts
Cope’s corydoras possess a unique ability to breathe atmospheric air by gulping it at the water's surface, thanks to a modified, highly vascularized intestine. This adaptation allows them to survive in oxygen-deprived environments. Additionally, their stiffened pectoral-fin spines can pierce human skin, and secretions from axillary glands at the base of each spine may be mildly toxic, so careful handling is advised.
