E.Coli is a common bacteria, a gram negative rod, found in the intestinal
tract of most animals, including humans. It is found in the water supplies
of almost any city to one tiny degree or another. As with most bacteria,
there are slight variations in strains around the country, some capable of
making you sick more or less than other strains. That's why you can drink
your local water without getting sick (you've built immunity to your local
strain), but if you travel to a distant city and drink their water, you can
get sick (because you don't have resistance to their strain). Sanitation
departments regularly check water supplies for the levels of these bacteria,
and make sure they are held to miniscule levels, but you are always getting a
few E. Coli bacterium in almost every glass of water you drink. Different
animals react differently to different bacteria. Diseases and bacteria which
would make, say, a Wolf sick, or which might kill an Aardvark, will usually
have little or no effect on, say, a human or a Raccoon. There are notable
exceptions, of course, but E.Coli tends to be more of a problem to humans
rather than animals. It is unlikely it would have any effect on fish, which
usually fall victim to other varieties of gram negative organisms. My
opinion would be to go ahead with your water changes and not to worry about
E.Coli affecting your fish.
