    A good write-up by The Washington Post that shows this story isn’t just a one-off!

    “Far from being an innocuous domestic animal, a goldfish freed in fresh water is an invasive species, an organism that is introduced to an environment, can quickly reproduce, outcompete native species and destroy a habitat. And even though they get less attention than invasive organisms such as Asian carp or zebra mussels, goldfish appear to be a growing problem in bodies of water across the United States and around the world, triggering warnings from government officials in Virginia, Washington state, Australia, Canada and elsewhere.

    “A few goldfish might seem to some like a harmless addition to the local water body — but they’re not,” the Minnesota Department of Natural Resources advised this year."
