Photo-based possible matches
Fish Disease Identifier uses a fish photo to suggest possible disease matches and practical next checks. It is designed as a starting point, not a final answer.
About
A fast starting point when a fish looks unhealthy
Fish Disease Identifier is built for aquarium owners who need a practical way to organize visible symptoms, possible causes, and next checks when a fish looks sick.
What the website covers
SickFish.app gives aquarium owners disease guides, symptom guides, and first-check resources. The mobile app is where photo scanning happens.
When to use it
Use it when you notice spots, torn fins, swelling, odd swimming, breathing changes, appetite loss, or a sudden decline in behavior.
Clear limits
Results may be wrong. Fish symptoms overlap, and photo quality, lighting, species differences, and tank conditions can change the interpretation.
Safety
Educational, not veterinary advice
Fish Disease Identifier can suggest likely matches from a photo, but it cannot confirm a disease, replace a veterinarian, promise an outcome, or choose medication for every tank.
For severe, worsening, or unclear symptoms, especially gasping, pineconing scales, open sores, collapse, or fast decline, consult an aquatic veterinarian or experienced aquarium professional.
Fish Disease Identifier provides educational guidance and possible matches from photos. Results are not veterinary advice and may be wrong. For severe, worsening, or unclear symptoms, consult an aquatic veterinarian or experienced aquarium professional.
Editorial responsibility
Fish Disease Identifier Editorial Team
Fish health guides are published under a collective editorial byline. The byline identifies the team responsible for researching, maintaining, and correcting the website content; it does not imply that a guide was examined or approved by a veterinarian.
Questions and corrections can be sent to niemiec.say@gmail.com. Material corrections are incorporated into the guide and its visible review date is updated when the content itself is reviewed again.
Editorial policy
How guides are prepared and reviewed
Guides begin with visible signs, urgent water and breathing checks, overlapping conditions, and conservative next steps. They avoid presenting a photograph or one symptom as a confirmed diagnosis.
Sources prioritize university extension material, veterinary manuals, and peer-reviewed research. Secondary aquarium references may provide practical context, but they do not replace stronger technical sources.
“Last content review” means the page was checked for clarity, consistency, safety language, and alignment with its cited sources. It is not a veterinary examination, diagnosis, certification, or personal treatment recommendation.
