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 action—not just species identification. WHAT YOU GET • A likely condition based on visible symptoms • Clear confidence, severity, and contagiousness guidance • Immediate actions and signs to monitor • Possible causes and useful aquarium water checks • Treatment options to consider • Prevention tips for healthier fish and tanks • 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.

I'm a retired Google engineer living in the Florida Keys. I love fishing, and I hate bad apps that are hard to use and sit behind paywalls. I started CatchReel to build a series of free apps that use cutting-edge AI for smarter fishing and boating. Fish101 is the first of the fleet. Snap a photo of any fish — Fish101 tells you what species it is, how good it tastes, and other fun facts about it. Free AI-based fish identifier for travelers, snorkelers, divers, anglers, aquarium-goers, and the curious. No signup. No ads. Completely free with no paid tier. Strong coverage of saltwater and freshwater sport fish, plus popular reef fish, public aquarium species, sharks, and rays. WHAT FISH101 DOES Take a photo of a fish (or pick one from your camera roll). In seconds, Fish101 identifies the species and shows you: • Common name and scientific name • A friendly description in plain English • Typical size, max size, max weight • Family and the region where it's found • Eating quality • A Wikipedia link if you want to dig deeper WHY FISH101 IS DIFFERENT Most fish ID apps are "free to download" but lock the real features behind a paid subscription. Fish101 is genuinely free. • Unlimited identifications — no daily caps, no quotas • No subscription, no premium tier, no upgrade prompts • No signup, no email, no account • No ads, no newsletters, no popups • No tracking — photos are processed and discarded; only your local history (which you control) stays on your phone Most fish ID apps are also based on older technology with limited species coverage, lower accuracy, and only one fish per photo. • Built on a cutting-edge AI model for fish identification • Identifies sport fish, reef fish, public-aquarium fish, sharks, rays, and commercial seafood • Saltwater and freshwater species from coasts around the world • Identifies multiple fish in a single photo WHO IT'S FOR • Travelers fishing or snorkeling somewhere new • Beach trips, public-aquarium visits, scuba dives • Anglers visiting a new region or trying saltwater for the first time • Curious kids and parents at the dock • Restaurant diners wondering what they ordered HOW TO USE IT 1. Open the app — straight to the camera 2. Snap a fish (or pick one from your photo library) 3. Get the species name and details in seconds 4. Save it to your history if you want to remember Fish101 is a utility, not a platform. One thing well: identify fish from a photo. No accounts, no walls, no nags.
