I'm not sure if it is the same thing or not but I had a similar thing happen to my Columbian tetras,only the black spots took on a vertical pattern.Only the Columbians were affected though.They both died,and I finally attributed it to the very high levels of nitrate that I had at that time.If my theory is correct,Columbian tetras have a low tolerance to high nitrate levels.
