How about a 100 pound fish hurtling themselves out of your pond directly at
your head every time you turn on the lights?
Here's some quotes:
"they are often seen breaking the water surface many meters ahead and along
the sides of our electrofishing boats. Asian carp have often entered our
boats without the use of dip nets. In fact, many of our staff members have
been hit multiple times by large jumping fish."
"Illinois residents along the Mississippi, Ohio and Illinois rivers have
been subjected to a strange sight in the past year-flying carp. It's not
unusual for bighead and silver carp to land in boats, occasionally bouncing
off shocked passengers, injuring drivers and, in some cases, causing damage
to the boats. These carp have a habit of jumping when disturbed..."
Seems like a bad choice of a pond pet to me, but these things are in the
Mississippi River valley now and headed for a river or lake near you. See
