However,, if water quality is maintained at high standard and the pH,alkalinity,etc are suitable for the fish, many fish can fight off infections,bacteria,and or other pathogens. And it is also known that no mecications will help fish in poor water conditions so it really does pay to maintain the tank properly.
I completely agree. Well said. B.
