About the Species
Native to South America, Green Corydoras are bottom-dwelling catfish that naturally live in groups, spending their time foraging along the substrate and interacting with one another. Their peaceful temperament and social nature make them one of the best additions to a wide range of aquariums.
These fish are constantly in motion — sifting, exploring, and working together — adding life and purpose to the lower level of your tank.
Color, Size & Presence
Green Corydoras develop a metallic green to bronze coloration that shifts depending on lighting and angle, giving them a subtle but striking appearance.
• Adult Size: 2.5–3 inches
• Body Type: Rounded, armored catfish
• Coloration: Green-bronze with reflective sheen
• Visual Impact: Subtle individually — impressive in groups
👉 While one is easy to overlook, a group transforms the entire tank.
Behavior & Compatibility
Green Corydoras are among the most peaceful fish in the hobby and thrive when kept in groups.
• Completely peaceful — ideal for community tanks
• Strong schooling/shoaling behavior
• Best kept with other non-aggressive species
• Active during the day and highly visible
Their social behavior means they are rarely still — constantly interacting and moving together across the tank floor.
Tank Requirements
These fish are extremely forgiving but perform best in a stable, well-maintained setup:
• Temperature: 72–78°F
• pH Range: 6.0–7.5
• Tank Size: 20 gallons minimum
• Substrate: Sand or smooth substrate preferred
• Environment: Driftwood, plants, and open bottom space
A soft substrate is important to protect their sensitive barbels as they forage.
Feeding
Green Corydoras are bottom feeders but should never be left to rely on leftovers alone.
• Sinking pellets and wafers
• Frozen foods (bloodworms, brine shrimp)
• Occasional live foods
They are eager eaters and will quickly learn feeding routines.
Breeding Overview
Green Corydoras are one of the easiest Cory species to breed in an aquarium setting.
• Egg layers — often triggered by water changes
• Females deposit eggs on glass, plants, or decor
• No parental care — eggs can be removed for raising
• Fry are hardy and grow steadily with proper care
This makes them an excellent choice for hobbyists interested in breeding and raising their own fish.
