Description
Quick answer: green corydoras (Corydoras aeneus) are the bronze cory, a hardy 6 cm catfish supplied at 2.5 to 2.8 cm. They are the most widely stocked cory in the trade because they ship well, eat anything and suit almost any community tank.
There is no clever angle to this fish. It is the volume line. Every shop needs a cory that costs little, survives the trip, works in a community tank and can be sold to someone who has never kept a catfish before. Aeneus does that better than anything else on the market.
Identification
A metallic bronze to green body with a pale belly, a dark band behind the dorsal fin and a slightly humped profile in mature females. Males are slimmer and more angular. Adults reach around 6 to 7 cm, so this is a medium cory rather than a dwarf.
Water parameters
They accept 22 to 27 degrees Celsius and pH 6.0 to 7.8, which covers most community tanks. A sand base protects the barbels, and a group of six or more keeps them visible. They eat sinking pellets, frozen food and leftover flake.
They are also long lived. A well kept group will be in the tank for years, which is a point worth making to a customer choosing between this and a cheaper, shorter lived alternative.
Wholesale supply
Aeneus is armoured and robust, which is why it ships in volume with low losses. Fish are fasted for 24 hours, bagged in oxygen and packed at standard density. Grading at 2.5 to 2.8 cm gives retail tanks an even size and a predictable price.

Longevity and tank mates
Aeneus is a long lived fish, often reaching ten years or more in a well kept tank. That matters for the sales conversation: it is not a replacement fish, it is a commitment. Tank mates should be peaceful and large enough not to be eaten, from tetras and rasboras to livebearers and small cichlids. Avoid aggressive bottom feeders and anything that guards a cave, because a cory that cannot feed properly will fade within weeks.
Frequently asked questions
Are green and bronze corydoras the same fish?
Yes. Both names refer to Corydoras aeneus, depending on the colour the fish shows under light.
How many should be kept together?
Six or more. They are social and show far more activity in a group.
Do they eat algae?
Not really. They are omnivores that need sinking food, not algae grazers.
