Hi!
Don't know if anybody notes if I pick up this old thread.
To me, the diseases are hard to identify, too. It doesn't help that the medicines state which sickness they cure (green/white) if the spots themselves are not identifyable. They look rather golden than green or white.
I already spent much too much money on medicine. Nevertheless, I am not able to cure my Greenfin Spotanus :-( I tried each of the medicines several times without any effect.
