The Bronze Corydoras is a bottom dweller and rarely swims to the surface.
Over the years I have purchased several Bronze Corydoras for my community tanks, but somehow they have disappeared. Normally the Bronze Corydoras is considered an easy fish to keep and breed. They are a social species and should be kept in groups of at least 5 fish.
My own Bronze Corydoras has showed initial signs of spawning several times, but I haven't seen any eggs.
