Is your fish showing white spots, torn fins, swelling, cloudy eyes, unusual color, or changes in behavior? Take a clear photo and get practical fish health guidance in seconds. Fish Disease Identifier uses AI-assisted photo analysis to help aquarium owners understand a likely visible health issue, how urgent it may be, and what to check next. It is built for actionβnot just species identification. WHAT YOU GET β’ A likely condition based on visible symptoms β’ Clear confidence, severity, and contagiousness guidance β’ Immediate actions and signs to monitor β’ Possible causes and useful aquarium water checks β’ Treatment options to consider β’ Prevention tips for healthier fish and tanks β’ Scan history to revisit and compare earlier cases COMMON FISH HEALTH ISSUES The app can provide guidance for visible signs associated with common aquarium problems such as ich or white spot disease, fin rot, fungal and bacterial infections, velvet, dropsy, popeye, cloudy eye, ulcers, bloating, torn fins, and external parasites. HOW IT WORKS 1. Take or upload a clear photo of the affected fish. 2. Review the most likely condition and confidence level. 3. Check urgency, tank-care steps, treatment guidance, and prevention tips. 4. Save the result to your fish health history. MADE FOR AQUARIUM KEEPERS Whether you care for a betta, tropical fish, or a freshwater community aquarium, Fish Disease Identifier helps turn worrying symptoms into a clearer next step. Use it to organize observations, react earlier, and make more informed care decisions. For better results, use a sharp, well-lit photo with one fish clearly visible. Always check water quality and confirm that any treatment is safe for your fish species, plants, and invertebrates. IMPORTANT Results are AI-generated guidance based on visible signs and may be incomplete or incorrect. The app does not replace diagnosis or treatment by a qualified aquatic veterinarian. If symptoms are severe, rapidly worsening, or unclear, consult an aquatic veterinarian or experienced fish health professional.
