sudden drops in temp can bring in ich. and the fish are coming out of a long period
with no food, so they are weak and their immune system is down if the water temp is
less than 55oF.
it is important to grab one of those fish and do the physical on it if it hasnt been
dead too long. the diagnosis is for live fish, but can do it on fresh dead

post mortem changes, the gills go white, the slime coat thicks up really fast. but
inside the fish possible to see if there is infection, if the liver is huge or gone,
etc. http://weloveteaching.com/puregold/d...e/gf_anat.html
