An interesting video regarding parasite ID

What I especially found interesting is that the narrator repeated the fact that a healthy, non-stressed fish, living with good water conditions will normally be able to build defenses against diseases. IOW, these critters are in your water and on your fish — they are present whether we like it or not. A stressed fish or a fish weakened by poor water quality is unable to build its natural defenses. THUS, THE REASON WE ARE ALWAYS PUSHING GOOD WATER QUALITY!

Great information! We used to do this in science class in school - go out and find a pond or puddle and look at a single drop of the water under the microscope. We'd see all kinds of things in there!
