This fish is still sick. That is not typical behavior for a Corydoras. Can you describe his behavior in more detail. Also describe the conditons he is in/around. Things such as: Any chemicals or odors in the air around the tank, tap water quality unchanged, no chemical or metals in contact with the tank, anything new added to the tank recently, has salt been added to the water. Anything you can tell me will help.
