OK guys. I got tired of hearing all this arguing. So, I did some research. Here is what I found:
Don't go near the water By Alan Cantwell, Jr., M.D. A New Plague Endangers American Rivers A new microbe is stalking some of America's most important rivers and estuaries. Dubbed the "cell from hell," this microscopic one-celled organism has already been implicated in the death of billions of fish on the Eastern seaboard, and poses a serious health threat to fishermen and people exposed to these toxic waters.
Discovered a decade ago in the fish tanks of an aquatic laboratory headed by fish pathologist Dr. Edward Noga at the North Carolina School of Veterinary Medicine, this killing agent is not a bacterium or a virus, but has been identified as a dinoflagellate. Some species of dinoflagellates, or "dinos," are better known as "algae."
This "cell" is similar to the fungus that creates athletes foot.
Could there be a connection to cycling a tank with a shoe and this deadly desease? What about the Asia connection I eluded to before?
Here is another pretty good article:
