Excerpt from a Gerald Bassleer YouTube video on diagnosing fish diseases. In this opening segment the speaker asks whether correct diagnoses can be made with the naked eye, presents two fish images (or examples) and states he cannot tell without a microscope, indicating the video will show what to look for and that microscopy is needed for accurate diagnosis.
