I think it may have been an ammonia problem (which only affected the corys, and not the other fish, because corys are so super-sensitive.) I've been talking in another thread about this. I didn't have many fish in the tank before I got the corys, so I think the levels of bacteria dropped because the bioload was small. and when I bought a heap of corys, the ammonia suddenly peaked because there weren't enough bacteria to cope with them.
I'm not sure how I can solve this problem, as it seems likely to happen no matter what I do. But lots of water changes might help! anyway, at the moment I think I'd be overstocking if I got any more fish, so for now, no corys
