Does anybody have a particular source to refer to for diseases? A book or website that is very detailed and has most, if not all common diseases. With decent pictures, too. I can't stand the "sketches" or "animations".
I have the Manual of Fish Health (Andrews, et al) which is useful, and has some good images. There's a lot of really good info in it on fish health and avoiding disease, written for hobbyists. Diagnosis info is good, but the treatment info can be a little vague if you're looking for a book that tells you to treat with a specific brand/med.
