Visible signs first
Symptoms like white spots, fuzzy growth, torn fins, or red gills are often easier to start with than guessing a disease name.
Symptom-first checks
Fish Symptom Checker
Start with what you can see: white spots, torn fins, cloudy eyes, swollen belly, gasping, clamped fins, unusual swimming, or appetite changes. Then compare possible causes and scan a photo if you need another starting point.
Fish Disease Identifier
Start with one clear photo.
Scan your fish and compare likely disease matches, possible causes, and next checks to consider.

Fast visible checks
- Choose the symptom that best matches what you see right now.
- Compare likely causes such as ich, fin rot, swim bladder trouble, parasites, or water-quality stress.
- Check recent water changes, new fish introductions, food changes, temperature, and water parameters.
- Use Fish Disease Identifier when you want photo-based possible matches and next checks.
Behavior matters
Floating sideways, gasping, rubbing, hiding, and not eating can change which possible causes deserve attention.
Water can mimic disease
Ammonia, nitrite, low oxygen, and temperature stress can look like illness, so water checks belong near the top of the process.
Scan when unsure
A clear photo can help the app suggest likely matches and organize practical next checks without replacing expert advice.
