This tool evaluates symptoms of the most common
aquarium fish diseases and data about your tank and presents
possible causes.
Note that this site only performs the diagnostics among about top 40 conditions, but confirmation and treatment should be performed carefully.
Also, remember not to
over-treat and specially avoid using medicines on your main tank.
Tip: Well cared and balanced tanks, as well adapting new fish in separate tanks, are the best form to prevent disease.
