Please, help! Is my Albino Cory sick?

[kalabreeze]

just a headsup... there's no reason to isolate the healthy cories... the columnaris will affect all fish if caught, not just the corydoras.

I understand...I probably panicked after one cory died, other cory was swimming very fast and flicking, the other one was still on the bottom behind the plant. They seem to be fine now, I moved them back to the tank, I do not know what it was.
Corys always give me a scare, very funny little guys, my favorite fish
