It looks like many of those skulls full of mush that lined up in droves to see Disney's Finding Nemo have started flushing their fish down the toilet. While they are hoping to share with their pets the playful "Nemo" experience, they are actually sending them to watery graves. The LA Times notes:

Margie Valadez, a dispatcher for RotoRooter, is used to calls from upset customers whose watches, rings or even cell phones were accidentally flushed down the toilet. Lately, though, she's been taking calls from hysterical parents asking if plumbers can rescue fish.

"I hear kids crying in the background," she said. "But there's nothing we can do. They're gone."

Salt water fish are killed pretty quickly by the fresh water. (Even quicker if they have those blue tablets in there) Fresh water fish, may survive long enough to reach the grinder (last item).
