I have purchased Edward Noga's textbook on Fish Disease and Treatment. It's a textbook for vets and complicated. However, there's plenty of information on diseases that affect tropical fish plus other conditions that adversely affect fish health with scientific explanations. A microscope would be an excellent aid as well. I look at the pictures and read the text about them and hope that my fish never get sick like that. Yuk.
