Very often, diseased fishes show a limited range of lesions, and most of these just mean the fish is sick. Apart from perhaps white spot disease, many clinical signs of illness such as skin ulcers, bloat, dropsy, pop-eye and flashing are not specific to any disease agent.
I often receive calls from clients who’d been to multiple places to get advice on what to do. Some good advice, and some less than optimal. But it’s often those who speak most convincingly that we tend to listen to… and perhaps to our detriment.
I’d like to share this comic strip from last week’s papers to illustrate what we fish keepers, and fish veterinarians deal with.
