Well after 5 years I think I have gotten my first disease/ailment in one of my tanks. My opaline which is almost 3 years old has a light discoloration behind and slightly above one of its eyes. That spot has gone from bluish white to a light yellowish in color. Not sure if this is a sign of age, of perhaps the dreaded hole in the head that I have read and heard about. What do you all think? Yes I have already put him in a QT tank, but not sure if I should try to treat or leave alone and see what happens.
