thanks for that info, it probably came from the showa.
i was always worried about yellowy noses and thought that if you had yellow heads it meant your stock would always have yellow heads but that fish cleared right up.
Hey I wonder how long it takes for the sumi in the head to finish? Is this always the last place for sumi to finish? I have noticed the same thing in showa.
