This fish passed away yesterday. Nothing I can do about that, but I want to know what killed him. Pictures are one day apart and his flesh disintegrated rapidly. Any thoughts on what this disease might have been? I feel terrible that we couldn’t save him in time.

Agree!Looks like it died from Duck Lip disease Columnaris.
Isn’t that contagious? All other fish are fine.
What are the symptoms?
