FROM FRANK MAGALLANES:
In the past, I covered this topic in my old pira-news2000 email list. Fishman2 reminded that a similar post was made at another message board that was asking about the problem.
In the particular case:
A pirana may have half the body blackened giving it a two-toned appearance. This is most certainly related to nervous system damage and is connected with a type of stroke fish suffer from stress or other condition.
To my knowledge there are no known cures and can lead to mortality depending how bad the damage is.
