Just theorizing, though. I know most places that have fish in their fountains now have
signs asking that pennies (or any coin) not be thrown in the water. I would assume this to
be the reason.

Pennies in the last decade or so have been made of copper plated zinc.

Neither is safe for fish.

And to make things more fun the presence of zinc significantly
increases the toxicity of copper...

That reminds me.

Little children sometimes swallow coins. The old penny, solid bronze,
was not too bad. The newer pennies with the zinc inside are deadly.
Remember that around the brats.

Hmmmm. While Zinc Toxicosis is nothing to sneer at, "deadly" is exaggerating
things a bit, methinks.
