For a few months now, I have had 2 female Corydoras armatus living in a 75 gallon tetra community. Just 2, because that was all I could get at the time. I found them after all the others had been sold. It's become one of my favourites, but I confess, I haven't been seeing a lot of them. I love the tall dorsal.
But I haven't liked their situation - no Corys should ever be as isolated as a group of two. They are really social fish.
I dropped in to a specialty aquarium fish store a few weeks back, and bought small groups of 3 species of Corys. They, and some wild caught cf incolicana from another source came out of quarantine today. They are an undescribed species known as sp CW 123, or sometimes, the yellow Cory. Even though we don't know how Corys know each other, I took a chance their colouration would help with my armatus. The communication is probably chemical, but as a human, I hope it's visual too.
I also added tthe incolicana types.This was done last night.
Nothing replaces its own species for a Corydoras, but I can report that the armatus are suddenly magically visible, even at times swimming with the other two species. The Cory test is night-time, when species sleep in their own groups. Maybe someday, I'll find more armatus and be able to give them the company they deserve. But at least they feel okay swimming at the front of the glass now. That's progress.
