TankDoc: AI Fish Doctor

White spots or faded colors on your fish? Take a photo to explore possible causes and care steps with TankDoc. AI guidance is not a confirmed diagnosis.

PHOTO-BASED AI ASSESSMENT
Use a fish photo to explore possible problems and care suggestions. Results describe possibilities, not a confirmed diagnosis or a guaranteed treatment. Seek qualified help when a fish is getting worse.

SPECIES IDENTIFICATION AND CATALOGS
Get AI identification suggestions for fish, aquatic plants and invertebrates. Explore catalog care profiles and check identification results before relying on them. Compare tank mates with the fish compatibility tool, including temperature, water parameters and care conditions.

WATER TESTS AND PARAMETER HISTORY
Use the photo tool to help read a water test strip. Check the suggested readings against the strip manufacturer's color chart. Log pH and other water parameters, then view changes over time in charts.

EVERYDAY AQUARIUM CARE
Keep tanks, care notes and reminders in one place. Plan water changes and other maintenance tasks. Browse feeding, setup, water quality and disease guides as you build your aquarium care routine.

AI features require an internet connection. Usage limits and in-app purchases may apply; details are shown in the app. AI results can be wrong. TankDoc does not replace a qualified professional's assessment.

Keep an aquarium log to connect daily observations with water readings. Compare the care needs of aquarium species before choosing tank mates. Review your aquarium routine when water conditions change.
