the best way to keep him mean is to put him in his life time tank while small and young. this way he won't have to experience a tank change. taking piranha out of the tank by net can reduce they're confidence and could take months before they get back to normal and sometimes will never be as agreesive as they once were. of course there are special cases of which this does not apply.
thanks for that info. Unfortunately hes not in his life time tank yet, but should be sometime next year. Hes in a 3ft now and will be going into a 6-7ft.
