The Oscar is about 6-7" and has had hole in the head since 2 years ago. Is this contagious? I know it is caused by poor water conditions and was told that if I put it in a clean tank with clean fish, they will not get it. Just wanting to know. BTW I am going to try to post a vid of it in the future. A buddy of mine doesn't have the heart to dispose of it so I want to make use of it.
