Just a reminder that these are guidelines that have been set by the masters. A newbie would be advised to patiently study these different traits and to see as many fish as he could see before being able to differentiate between a kamfa and a zhen zou. Other experts would say that a simpler way of diffentiating between a kamfa and a zz is that if the fish has features which are predominantly amhipolus trimaculatus then it is a zz. If it looks more like a vieja then its a kamfa.
Here is a picture of a zz and a trimaculatus.
