Hi, we have 3 Corydoras Juli and 3 Albino Corys. Do they school?
They might, but that's because: 1. There is danger near by. OR 2. There is no choice because there isn't more of there own species and they're social fish, so they'd start schooling with each other. They will enjoy having more of their own species so they can school with each other and they'd also show a more natural behavior.
