Bronze cory
Corydoras aeneus
Corydoras aeneus is a hardy, active corydoras suitable for many calm communities. Its reputation as an easy fish does not remove two basic needs: living in a group and having safe substrate.
It constantly explores the bottom with its barbels, so sharp gravel and accumulated dirt are real problems.

Growth and behavior
Juvenile to adult
Juvenile
As a juvenile it feels safer in a group and usually uses the bottom with coordinated movement. An insufficient group can increase stress and erratic behavior.
Shift
The transition to adulthood usually brings more stable behavior when group size, space and parameters are suitable.
Adult
As an adult it keeps a strong social pattern and is more stable in adequate groups. In balanced communities it usually occupies the bottom without causing major conflict.

High risk
Astronotus ocellatus + Corydoras aeneus: there is a predation risk due to size difference, mouth capacity or feeding behavior.
Essential care
Keep a group, fine sand and well-oxygenated water. Avoid prolonged extremes, especially high heat when combined with species such as discus. Filtration should move water without disturbing the substrate too much.
