The only thing that I have implied is that when one buys a FH, the new owner needs to follow a simple preventative protocol such as outlined above. Doing so is not wasting time, in most cases it could very well mean having a fish that is alive for years to come, or not. No need for a scope, in fact, attempting to correctly ID pathogens under a microscope is often best left to experts in that field. A well educated guess trumps death every time, and in the vast majority of these cases those educated guesses result in a positive outcome. In this case, my educated guess comes from first hand experience with keeping FH that were imported from Bangkok etc, and arrived packing heat. I cured them all, without the need for a microscope. I must just be good at guessing. lol
